Common examples of these types of applications include:\n\u2753 Question Answering over specific documents\nDocumentation\nEnd-to-end Example: Question Answering over Notion Database\n\ud83d\udcac Chatbots\nDocumentation\nEnd-to-end Example: Chat-LangChain\n\ud83e\udd16 Agents\nDocumentation\nEnd-to-end Example: GPT+WolframAlpha\nGetting Started#\nCheckout the below guide for a walkthrough of how to get started using LangChain to create an Language Model application.\nGetting Started Documentation\nModules#\nThere are several main modules that LangChain provides support for.\nFor each module we provide some examples to get started, how-to guides, reference docs, and conceptual guides.\nThese modules are, in increasing order of complexity:\nPrompts: This includes prompt management, prompt optimization, and prompt serialization.\nLLMs: This includes a generic interface for all LLMs, and common utilities for working with LLMs.\nDocument Loaders: This includes a standard interface for loading documents, as well as specific integrations to all types of text data sources.\nUtils: Language models are often more powerful when interacting with other sources of knowledge or computation. This can include Python REPLs, embeddings, search engines, and more. LangChain provides a large collection of common utils to use in your application.", "source": "https://langchain.readthedocs.io/en/latest/index.html"} {"id": "9c04de564ed3-1", "text": "Chains: Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.\nIndexes: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.\nAgents: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.\nMemory: Memory is the concept of persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.\nChat: Chat models are a variation on Language Models that expose a different API - rather than working with raw text, they work with messages. LangChain provides a standard interface for working with them and doing all the same things as above.\nUse Cases#\nThe above modules can be used in a variety of ways. LangChain also provides guidance and assistance in this. Below are some of the common use cases LangChain supports.\nAgents: Agents are systems that use a language model to interact with other tools. These can be used to do more grounded question/answering, interact with APIs, or even take actions.\nChatbots: Since language models are good at producing text, that makes them ideal for creating chatbots.\nData Augmented Generation: Data Augmented Generation involves specific types of chains that first interact with an external datasource to fetch data to use in the generation step. Examples of this include summarization of long pieces of text and question/answering over specific data sources.", "source": "https://langchain.readthedocs.io/en/latest/index.html"} {"id": "9c04de564ed3-2", "text": "Question Answering: Answering questions over specific documents, only utilizing the information in those documents to construct an answer. A type of Data Augmented Generation.\nSummarization: Summarizing longer documents into shorter, more condensed chunks of information. A type of Data Augmented Generation.\nQuerying Tabular Data: If you want to understand how to use LLMs to query data that is stored in a tabular format (csvs, SQL, dataframes, etc) you should read this page.\nEvaluation: Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.\nGenerate similar examples: Generating similar examples to a given input. This is a common use case for many applications, and LangChain provides some prompts/chains for assisting in this.\nCompare models: Experimenting with different prompts, models, and chains is a big part of developing the best possible application. The ModelLaboratory makes it easy to do so.\nReference Docs#\nAll of LangChain\u2019s reference documentation, in one place.

we do not think we have a perfect solution.\nSo we very much welcome feedback, contributions, integrations, and thoughts on this.\nHere is what we have for each problem so far:\n# 1: Lack of data\nWe have started LangChainDatasets a Community space on Hugging Face.\nWe intend this to be a collection of open source datasets for evaluating common chains and agents.", "source": "https://langchain.readthedocs.io/en/latest/use_cases/evaluation.html"} {"id": "72fe806493dd-1", "text": "We intend this to be a collection of open source datasets for evaluating common chains and agents.\nWe have contributed five datasets of our own to start, but we highly intend this to be a community effort.\nIn order to contribute a dataset, you simply need to join the community and then you will be able to upload datasets.\nWe\u2019re also aiming to make it as easy as possible for people to create their own datasets.\nAs a first pass at this, we\u2019ve added a QAGenerationChain, which given a document comes up\nwith question-answer pairs that can be used to evaluate question-answering tasks over that document down the line.\nSee this notebook for an example of how to use this chain.\n# 2: Lack of metrics\nWe have two solutions to the lack of metrics.\nThe first solution is to use no metrics, and rather just rely on looking at results by eye to get a sense for how the chain/agent is performing.\nTo assist in this, we have developed (and will continue to develop) tracing, a UI-based visualizer of your chain and agent runs.\nThe second solution we recommend is to use Language Models themselves to evaluate outputs.\nFor this we have a few different chains and prompts aimed at tackling this issue.\nThe Examples#\nWe have created a bunch of examples combining the above two solutions to show how we internally evaluate chains and agents when we are developing.\nIn addition to the examples we\u2019ve curated, we also highly welcome contributions here.\nTo facilitate that, we\u2019ve included a template notebook for community members to use to build their own examples.\nThe existing examples we have are:\nQuestion Answering (State of Union): An notebook showing evaluation of a question-answering task over a State-of-the-Union address.\nQuestion Answering (Paul Graham Essay): An notebook showing evaluation of a question-answering task over a Paul Graham essay.", "source": "https://langchain.readthedocs.io/en/latest/use_cases/evaluation.html"} {"id": "72fe806493dd-2", "text": "SQL Question Answering (Chinook): An notebook showing evaluation of a question-answering task over a SQL database (the Chinook database).\nAgent Vectorstore: An notebook showing evaluation of an agent doing question answering while routing between two different vector databases.\nAgent Search + Calculator: An notebook showing evaluation of an agent doing question answering using a Search engine and a Calculator as tools.\nOther Examples#\nIn addition, we also have some more generic resources for evaluation.\nQuestion Answering: An overview of LLMs aimed at evaluating question answering systems in general.\nData Augmented Question Answering: An end-to-end example of evaluating a question answering system focused on a specific document (a VectorDBQAChain to be precise).

sources\nAdditional Related Resources\nQuestion Answering#\nQuestion answering in this context refers to question answering over your document data.\nFor question answering over other types of data, like SQL databases or APIs, please see here\nFor question answering over many documents, you almost always want to create an index over the data.\nThis can be used to smartly access the most relevant documents for a given question, allowing you to avoid having to pass all the documents to the LLM (saving you time and money).\nSee this notebook for a more detailed introduction to this, but for a super quick start the steps involved are:\nLoad Your Documents\nfrom langchain.document_loaders import TextLoader\nloader = TextLoader('../state_of_the_union.txt')\nSee here for more information on how to get started with document loading.\nCreate Your Index\nfrom langchain.indexes import VectorstoreIndexCreator\nindex = VectorstoreIndexCreator().from_loaders([loader])\nThe best and most popular index by far at the moment is the VectorStore index.\nQuery Your Index\nquery = \"What did the president say about Ketanji Brown Jackson\"\nindex.query(query)\nAlternatively, use query_with_sources to also get back the sources involved\nquery = \"What did the president say about Ketanji Brown Jackson\"\nindex.query_with_sources(query)\nAgain, these high level interfaces obfuscate a lot of what is going on under the hood, so please see this notebook for a lower level walkthrough.\nDocument Question Answering#\nQuestion answering involves fetching multiple documents, and then asking a question of them.\nThe LLM response will contain the answer to your question, based on the content of the documents.\nThe recommended way to get started using a question answering chain is:\nfrom

However, there are many instances where you may want the language model to generate text based not on generic data but rather on specific data. Some common examples of this include:\nSummarization of a specific piece of text (a website, a private document, etc.)\nQuestion answering over a specific piece of text (a website, a private document, etc.)\nQuestion answering over multiple pieces of text (multiple websites, multiple private documents, etc.)\nUsing the results of some external call to an API (results from a SQL query, etc.)\nAll of these examples are instances when you do not want the LLM to generate text based solely on the data it was trained over, but rather you want it to incorporate other external data in some way. At a high level, this process can be broken down into two steps:\nFetching: Fetching the relevant data to include.\nAugmenting: Passing the data in as context to the LLM.\nThis guide is intended to provide an overview of how to do this. This includes an overview of the literature, as well as common tools, abstractions and chains for doing this.\nRelated Literature#\nThere are a lot of related papers in this area. Most of them are focused on end-to-end methods that optimize the fetching of the relevant data as well as passing it in as context. These are a few of the papers that are particularly relevant:\nRAG: Retrieval Augmented Generation.", "source": "https://langchain.readthedocs.io/en/latest/use_cases/combine_docs.html"} {"id": "51c56b9b1fdb-1", "text": "RAG: Retrieval Augmented Generation.\nThis paper introduces RAG models where the parametric memory is a pre-trained seq2seq model and the non-parametric memory is a dense vector index of Wikipedia, accessed with a pre-trained neural retriever.\nREALM: Retrieval-Augmented Language Model Pre-Training.\nTo capture knowledge in a more modular and interpretable way, this paper augments language model pre-training with a latent knowledge retriever, which allows the model to retrieve and attend over documents from a large corpus such as Wikipedia, used during pre-training, fine-tuning and inference.\nHayStack: This is not a paper, but rather an open source library aimed at semantic search, question answering, summarization, and document ranking for a wide range of NLP applications. The underpinnings of this library are focused on the same fetching and augmenting concepts discussed here, and incorporate some methods in the above papers.\nThese papers/open-source projects are centered around retrieval of documents, which is important for question-answering tasks over a large corpus of documents (which is how they are evaluated). However, we use the terminology of Data Augmented Generation to highlight that retrieval from some document store is only one possible way of fetching relevant data to include. Other methods to fetch relevant data could involve hitting an API, querying a database, or just working with user provided data (eg a specific document that they want to summarize).\nLet\u2019s now deep dive on the two steps involved: fetching and augmenting.\nFetching#\nThere are many ways to fetch relevant data to pass in as context to a LM, and these methods largely depend\non the use case.\nUser provided: In some cases, the user may provide the relevant data, and no algorithm for fetching is needed.\nAn example of this is for summarization of specific documents: the user will provide the document to be summarized,", "source": "https://langchain.readthedocs.io/en/latest/use_cases/combine_docs.html"} {"id": "51c56b9b1fdb-2", "text": "and task the language model with summarizing it.\nDocument Retrieval: One of the more common use cases involves fetching relevant documents or pieces of text from\na large corpus of data. A common example of this is question answering over a private collection of documents.\nAPI Querying: Another common way to fetch data is from an API query. One example of this is WebGPT like system,\nwhere you first query Google (or another search API) for relevant information, and then those results are used in\nthe generation step. Another example could be querying a structured database (like SQL) and then using a language model\nto synthesize those results.\nThere are two big issues to deal with in fetching:\nFetching small enough pieces of information\nNot fetching too many pieces of information (e.g. fetching only the most relevant pieces)\nText Splitting#\nOne big issue with all of these methods is how to make sure you are working with pieces of text that are not too large.\nThis is important because most language models have a context length, and so you cannot (yet) just pass a\nlarge document in as context. Therefore, it is important to not only fetch relevant data but also make sure it is in\nsmall enough chunks.\nLangChain provides some utilities to help with splitting up larger pieces of data. This comes in the form of the TextSplitter class.\nThe class takes in a document and splits it up into chunks, with several parameters that control the\nsize of the chunks as well as the overlap in the chunks (important for maintaining context).\nSee this walkthrough for more information.\nRelevant Documents#\nA second large issue related fetching data is to make sure you are not fetching too many documents, and are only fetching\nthe documents that are relevant to the query/question at hand. There are a few ways to deal with this.", "source": "https://langchain.readthedocs.io/en/latest/use_cases/combine_docs.html"} {"id": "51c56b9b1fdb-3", "text": "One concrete example of this is vector stores for document retrieval, often used for semantic search or question answering.\nWith this method, larger documents are split up into\nsmaller chunks and then each chunk of text is passed to an embedding function which creates an embedding for that piece of text.\nThose are embeddings are then stored in a database. When a new search query or question comes in, an embedding is\ncreated for that query/question and then documents with embeddings most similar to that embedding are fetched.\nExamples of vector database companies include Pinecone and Weaviate.\nAlthough this is perhaps the most common way of document retrieval, people are starting to think about alternative\ndata structures and indexing techniques specifically for working with language models. For a leading example of this,\ncheck out LlamaIndex - a collection of data structures created by and optimized\nfor language models.\nAugmenting#\nSo you\u2019ve fetched your relevant data - now what? How do you pass them to the language model in a format it can understand?\nFor a detailed overview of the different ways of doing so, and the tradeoffs between them, please see\nthis documentation\nUse Cases#\nLangChain supports the above three methods of augmenting LLMs with external data.\nThese methods can be used to underpin several common use cases, and they are discussed below.\nFor all three of these use cases, all three methods are supported.\nIt is important to note that a large part of these implementations is the prompts\nthat are used. We provide default prompts for all three use cases, but these can be configured.\nThis is in case you discover a prompt that works better for your specific application.\nQuestion-Answering\nSummarization\nprevious\nGenerate Examples\nnext\nQuestion Answering\n Contents\n \nOverview\nRelated Literature\nFetching\nText Splitting\nRelevant Documents\nAugmenting\nUse Cases\nBy Harrison Chase", "source": "https://langchain.readthedocs.io/en/latest/use_cases/combine_docs.html"} {"id": "51c56b9b1fdb-4", "text": "Text Splitting\nRelevant Documents\nAugmenting\nUse Cases\nBy Harrison Chase\n \n \u00a9 Copyright 2023, Harrison Chase.\n \n Last updated on Mar 22, 2023.", "source": "https://langchain.readthedocs.io/en/latest/use_cases/combine_docs.html"} {"id": "c14da507fa0e-0", "text": ".md\n.pdf\nSummarization\nSummarization#\nSummarization involves creating a smaller summary of multiple longer documents.\nThis can be useful for distilling long documents into the core pieces of information.\nThe recommended way to get started using a summarization chain is:\nfrom langchain.chains.summarize import load_summarize_chain\nchain = load_summarize_chain(llm, chain_type=\"map_reduce\")\nchain.run(docs)\nThe following resources exist:\nSummarization Notebook: A notebook walking through how to accomplish this task.\nAdditional related resources include:\nUtilities for working with Documents: Guides on how to use several of the utilities which will prove helpful for this task, including Text Splitters (for splitting up long documents).\nCombineDocuments Chains: A conceptual overview of specific types of chains by which you can accomplish this task.\nData Augmented Generation: An overview of data augmented generation, which is the general concept of combining external data with LLMs (of which this is a subset).\nprevious\nQuestion Answering\nnext\nQuerying Tabular Data\nBy Harrison Chase\n \n \u00a9 Copyright 2023, Harrison Chase.\n \n Last updated on Mar 22, 2023.", "source": "https://langchain.readthedocs.io/en/latest/use_cases/summarization.html"} {"id": "0a060ca34199-0", "text": ".md\n.pdf\nQuerying Tabular Data\n Contents \nDocument Loading\nQuerying\nChains\nAgents\nQuerying Tabular Data#\nLots of data and information is stored in tabular data, whether it be csvs, excel sheets, or SQL tables.\nThis page covers all resources available in LangChain for working with data in this format.\nDocument Loading#\nIf you have text data stored in a tabular format, you may want to load the data into a Document and then index it as you would\nother text/unstructured data.

A user\u2019s interactions with a language model are captured in the concept of ChatMessages, so this boils down to ingesting, capturing, transforming and extracting knowledge from a sequence of chat messages. There are many different ways to do this, each of which exists as its own memory type.\nIn general, for each type of memory there are two ways to understanding using memory. These are the standalone functions which extract information from a sequence of messages, and then there is the way you can use this type of memory in a chain.\nMemory can return multiple pieces of information (for example, the most recent N messages and a summary of all previous messages). The returned information can either be a string or a list of messages.\nIn this notebook, we will walk through the simplest form of memory: \u201cbuffer\u201d memory, which just involves keeping a buffer of all prior messages. We will show how to use the modular utility functions here, then show how it can be used in a chain (both returning a string as well as a list of messages).\nChatMessageHistory#\nOne of the core utility classes underpinning most (if not all) memory modules is the ChatMessageHistory class. This is a super lightweight wrapper which exposes convienence methods for saving Human messages, AI messages, and then fetching them all.\nYou may want to use this class directly if you are managing memory outside of a chain.\nfrom langchain.memory import ChatMessageHistory\nhistory = ChatMessageHistory()\nhistory.add_user_message(\"hi!\")\nhistory.add_ai_message(\"whats up?\")\nhistory.messages\n[HumanMessage(content='hi!', additional_kwargs={}),", "source": "https://langchain.readthedocs.io/en/latest/modules/memory/getting_started.html"} {"id": "fa88bc0d832e-1", "text": "history.messages\n[HumanMessage(content='hi!', additional_kwargs={}),\n AIMessage(content='whats up?', additional_kwargs={})]\nConversationBufferMemory#\nWe now show how to use this simple concept in a chain. We first showcase ConversationBufferMemory which is just a wrapper around ChatMessageHistory that extracts the messages in a variable.\nWe can first extract it as a string.\nfrom langchain.memory import ConversationBufferMemory\nmemory = ConversationBufferMemory()\nmemory.chat_memory.add_user_message(\"hi!\")\nmemory.chat_memory.add_ai_message(\"whats up?\")\nmemory.load_memory_variables({})\n{'history': 'Human: hi!\\nAI: whats up?'}\nWe can also get the history as a list of messages\nmemory = ConversationBufferMemory(return_messages=True)\nmemory.chat_memory.add_user_message(\"hi!\")\nmemory.chat_memory.add_ai_message(\"whats up?\")\nmemory.load_memory_variables({})\n{'history': [HumanMessage(content='hi!', additional_kwargs={}),\n AIMessage(content='whats up?', additional_kwargs={})]}\nUsing in a chain#\nFinally, let\u2019s take a look at using this in a chain (setting verbose=True so we can see the prompt).\nfrom langchain.llms import OpenAI\nfrom langchain.chains import ConversationChain\nllm = OpenAI(temperature=0)\nconversation = ConversationChain(\n llm=llm, \n verbose=True, \n memory=ConversationBufferMemory()\n)\nconversation.predict(input=\"Hi there!\")\n> Entering new ConversationChain chain...\nPrompt after formatting:\nThe following is a friendly conversation between a human and an AI.

This can be done easily by first converting the messages to normal python dictionaries, saving those (as json or something) and then loading those. Here is an example of doing that.\nimport json\nfrom langchain.memory import ChatMessageHistory\nfrom langchain.schema import messages_from_dict, messages_to_dict\nhistory = ChatMessageHistory()\nhistory.add_user_message(\"hi!\")\nhistory.add_ai_message(\"whats up?\")\ndicts = messages_to_dict(history.messages)\ndicts\n[{'type': 'human', 'data': {'content': 'hi!', 'additional_kwargs': {}}},\n {'type': 'ai', 'data': {'content': 'whats up?', 'additional_kwargs': {}}}]\nnew_messages = messages_from_dict(dicts)\nnew_messages\n[HumanMessage(content='hi!', additional_kwargs={}),\n AIMessage(content='whats up?', additional_kwargs={})]\nAnd that\u2019s it for the getting started!

For this notebook, it is important to understand the distinction we draw between agents and tools. An agent is the LLM powered decision maker that decides which actions to take and in which order. Tools are various instruments (functions) an agent has access to, through which an agent can interact with the outside world. When people generally use agents, they primarily talk about using an agent WITH tools. However, when we talk about serialization of agents, we are talking about the agent by itself. We plan to add support for serializing an agent WITH tools sometime in the future.\nLet\u2019s start by creating an agent with tools as we normally do:\nfrom langchain.agents import load_tools\nfrom langchain.agents import initialize_agent\nfrom langchain.llms import OpenAI\nllm = OpenAI(temperature=0)\ntools = load_tools([\"serpapi\", \"llm-math\"], llm=llm)\nagent = initialize_agent(tools, llm, agent=\"zero-shot-react-description\", verbose=True)\nLet\u2019s now serialize the agent.

So if that step requires multiple inputs, they need to be parsed from that. Therefor, the currently supported way to do this is write a smaller wrapper function that parses that a string into multiple inputs.\nFor a concrete example, let\u2019s work on giving an agent access to a multiplication function, which takes as input two integers. In order to use this, we will tell the agent to generate the \u201cAction Input\u201d as a comma separated list of length two. We will then write a thin wrapper that takes a string, splits it into two around a comma, and passes both parsed sides as integers to the multiplication function.\nfrom langchain.llms import OpenAI\nfrom langchain.agents import initialize_agent, Tool\nHere is the multiplication function, as well as a wrapper to parse a string as input.\ndef multiplier(a, b):\n return a * b\ndef parsing_multiplier(string):\n a, b = string.split(\",\")\n return multiplier(int(a), int(b))\nllm = OpenAI(temperature=0)\ntools = [\n Tool(\n name = \"Multiplier\",\n func=parsing_multiplier,\n description=\"useful for when you need to multiply two numbers together.

This decorator can be used to quickly create a Tool from a simple function. The decorator uses the function name as the tool name by default, but this can be overridden by passing a string as the first argument. Additionally, the decorator will use the function\u2019s docstring as the tool\u2019s description.\nfrom langchain.agents import tool\n@tool\ndef search_api(query: str) -> str:\n \"\"\"Searches the API for the query.\"\"\"\n return \"Results\"\nsearch_api\nTool(name='search_api', description='search_api(query: str) -> str - Searches the API for the query.', return_direct=False, verbose=False, callback_manager=, func=, coroutine=None)\nYou can also provide arguments like the tool name and whether to return directly.\n@tool(\"search\", return_direct=True)\ndef search_api(query: str) -> str:\n \"\"\"Searches the API for the query.\"\"\"\n return \"Results\"\nsearch_api", "source": "https://langchain.readthedocs.io/en/latest/modules/agents/examples/custom_tools.html"} {"id": "b5b0408ee424-4", "text": "\"\"\"Searches the API for the query.\"\"\"\n return \"Results\"\nsearch_api\nTool(name='search', description='search(query: str) -> str - Searches the API for the query.', return_direct=True, verbose=False, callback_manager=, func=, coroutine=None)\nModify existing tools#\nNow, we show how to load existing tools and just modify them.

When a user wants information on songs, You want the Agent to use the custom tool more than the normal Search tool. But the Agent might prioritize a normal Search tool.\nThis can be accomplished by adding a statement such as Use this more than the normal search if the question is about Music, like 'who is the singer of yesterday?' or 'what is the most popular song in 2022?' to the description.\nAn example is below.\n# Import things that are needed generically\nfrom langchain.agents import initialize_agent, Tool\nfrom langchain.llms import OpenAI\nfrom langchain import LLMMathChain, SerpAPIWrapper\nsearch = SerpAPIWrapper()\ntools = [\n Tool(\n name = \"Search\",\n func=search.run,\n description=\"useful for when you need to answer questions about current events\"\n ),\n Tool(\n name=\"Music Search\",\n func=lambda x: \"'All I Want For Christmas Is You' by Mariah Carey.\", #Mock Function\n description=\"A Music search engine.

The first type shows how to create a custom LLMChain, but still use an existing agent class to parse the output. The second shows how to create a custom agent class.\nCustom LLMChain#\nThe first way to create a custom agent is to use an existing Agent class, but use a custom LLMChain. This is the simplest way to create a custom Agent. It is highly reccomended that you work with the ZeroShotAgent, as at the moment that is by far the most generalizable one.\nMost of the work in creating the custom LLMChain comes down to the prompt. Because we are using an existing agent class to parse the output, it is very important that the prompt say to produce text in that format.

It is a string of text that is used to generate a response from the language model.\nPrompt Templates#\nPromptTemplates are a way to create prompts in a reproducible way. They contain a template string, and a set of input variables. The template string can be formatted with the input variables to generate a prompt. The template string often contains instructions to the language model, a few shot examples, and a question to the language model.\nPromptTemplates generically have a format method that takes in variables and returns a formatted string.\nThe most simple implementation of this is to have a template string with some variables in it, and then format it with the incoming variables.\nMore complex iterations dynamically construct the template string from few shot examples, etc.\nTo learn more about PromptTemplates, see Prompt Templates.\nAs an example, consider the following template string:\n\"\"\"\nPredict the capital of a country.\nCountry: {country}\nCapital:\n\"\"\"\nInput Variables#\nInput variables are the variables that are used to fill in the template string. In the example above, the input variable is country.\nGiven an input variable, the PromptTemplate can generate a prompt by filling in the template string with the input variable. For example, if the input variable is United States, the template string can be formatted to generate the following prompt:\n\"\"\"\nPredict the capital of a country.\nCountry: United States\nCapital:\n\"\"\"\nFew Shot Examples#", "source": "https://langchain.readthedocs.io/en/latest/modules/prompts/key_concepts.html"} {"id": "260d71273e1f-1", "text": "Country: United States\nCapital:\n\"\"\"\nFew Shot Examples#\nFew shot examples refer to in-context examples that are provided to a language model as part of a prompt. The examples can be used to help the language model understand the context of the prompt, and as a result generate a better response. Few shot examples can contain both positive and negative examples about the expected response.\nBelow, we list out some few shot examples that may be relevant for the task of predicting the capital of a country.\nCountry: United States\nCapital: Washington, D.C.\nCountry: Canada\nCapital: Ottawa\nTo learn more about how to provide few shot examples, see Few Shot Examples.\nExample selection#\nIf there are multiple examples that are relevant to a prompt, it is important to select the most relevant examples. Generally, the quality of the response from the LLM can be significantly improved by selecting the most relevant examples. This is because the language model will be able to better understand the context of the prompt, and also potentially learn failure modes to avoid.\nTo help the user with selecting the most relevant examples, we provide example selectors that select the most relevant based on different criteria, such as length, semantic similarity, etc. The example selector takes in a list of examples and returns a list of selected examples, formatted as a string. The user can also provide their own example selector.

The JSON string can be saved to a file, and then loaded back into a PromptTemplate using the deserialize method.

For more information, see Custom Prompt Templates.\nNote\nCurrently, the template should be formatted as a Python f-string. We also support Jinja2 templates (see Using Jinja templates). In the future, we will support more templating languages such as Mako.\nLoad a prompt template from LangChainHub#\nLangChainHub contains a collection of prompts which can be loaded directly via LangChain.\nfrom langchain.prompts import load_prompt\nprompt = load_prompt(\"lc://prompts/conversation/prompt.json\")\nprompt.format(history=\"\", input=\"What is 1 + 1?\")\nYou can read more about LangChainHub and the prompts available with it here.\nPass few shot examples to a prompt template#\nFew shot examples are a set of examples that can be used to help the language model generate a better response.\nTo generate a prompt with few shot examples, you can use the FewShotPromptTemplate.

This can make it easy to share, store, and version prompts. This notebook covers how to do that in LangChain, walking through all the different types of prompts and the different serialization options.\nAt a high level, the following design principles are applied to serialization:\nBoth JSON and YAML are supported. We want to support serialization methods that are human readable on disk, and YAML and JSON are two of the most popular methods for that. Note that this rule applies to prompts. For other assets, like Examples, different serialization methods may be supported.\nWe support specifying everything in one file, or storing different components (templates, examples, etc) in different files and referencing them. For some cases, storing everything in file makes the most sense, but for others it is preferrable to split up some of the assets (long templates, large examples, reusable components). LangChain supports both.\nThere is also a single entry point to load prompts from disk, making it easy to load any type of prompt.\n# All prompts are loaded through the `load_prompt` function.\nfrom langchain.prompts import load_prompt\nPromptTemplate#\nThis section covers examples for loading a PromptTemplate.\nLoading from YAML#\nThis shows an example of loading a PromptTemplate from YAML.\n!cat simple_prompt.yaml\n_type: prompt\ninput_variables:\n [\"adjective\", \"content\"]\ntemplate: \n Tell me a {adjective} joke about {content}.\nprompt = load_prompt(\"simple_prompt.yaml\")", "source": "https://langchain.readthedocs.io/en/latest/modules/prompts/examples/prompt_serialization.html"} {"id": "4981211d3af7-1", "text": "prompt = load_prompt(\"simple_prompt.yaml\")\nprint(prompt.format(adjective=\"funny\", content=\"chickens\"))\nTell me a funny joke about chickens.\nLoading from JSON#\nThis shows an example of loading a PromptTemplate from JSON.\n!cat simple_prompt.json\n{\n \"_type\": \"prompt\",\n \"input_variables\": [\"adjective\", \"content\"],\n \"template\": \"Tell me a {adjective} joke about {content}.\"\n}\nprompt = load_prompt(\"simple_prompt.json\")\nprint(prompt.format(adjective=\"funny\", content=\"chickens\"))\nTell me a funny joke about chickens.\nLoading Template from a File#\nThis shows an example of storing the template in a separate file and then referencing it in the config.

Like other methods, it can make sense to \u201cpartial\u201d a prompt template - eg pass in a subset of the required values, as to create a new prompt template which expects only the remaining subset of values.\nLangChain supports this in two ways: we allow for partially formatted prompts (1) with string values, (2) with functions that return string values. These two different ways support different use cases. In the documentation below we go over the motivations for both use cases as well as how to do it in LangChain.\nPartial With Strings#\nOne common use case for wanting to partial a prompt template is if you get some of the variables before others. For example, suppose you have a prompt template that requires two variables, foo and baz. If you get the foo value early on in the chain, but the baz value later, it can be annoying to wait until you have both variables in the same place to pass them to the prompt template. Instead, you can partial the prompt template with the foo value, and then pass the partialed prompt template along and just use that. Below is an example of doing this:\nfrom langchain.prompts import PromptTemplate\nprompt = PromptTemplate(template=\"{foo}{bar}\", input_variables=[\"foo\", \"bar\"])\npartial_prompt = prompt.partial(foo=\"foo\");\nprint(partial_prompt.format(bar=\"baz\"))\nfoobaz\nYou can also just initialize the prompt with the partialed variables.\nprompt = PromptTemplate(template=\"{foo}{bar}\", input_variables=[\"bar\"], partial_variables={\"foo\": \"foo\"})\nprint(prompt.format(bar=\"baz\"))\nfoobaz\nPartial With Functions#", "source": "https://langchain.readthedocs.io/en/latest/modules/prompts/examples/partial.html"} {"id": "2d2ff4b69a87-1", "text": "print(prompt.format(bar=\"baz\"))\nfoobaz\nPartial With Functions#\nThe other common use is to partial with a function. The use case for this is when you have a variable you know that you always want to fetch in a common way. A prime example of this is with date or time. Imagine you have a prompt which you always want to have the current date. You can\u2019t hard code it in the prompt, and passing it along with the other input variables is a bit annoying. In this case, it\u2019s very handy to be able to partial the prompt with a function that always returns the current date.\nfrom datetime import datetime\ndef _get_datetime():\n now = datetime.now()\n return now.strftime(\"%m/%d/%Y, %H:%M:%S\")\nprompt = PromptTemplate(\n template=\"Tell me a {adjective} joke about the day {date}\", \n input_variables=[\"adjective\", \"date\"]\n);\npartial_prompt = prompt.partial(date=_get_datetime)\nprint(partial_prompt.format(adjective=\"funny\"))\nTell me a funny joke about the day 02/27/2023, 22:15:16\nYou can also just initialize the prompt with the partialed variables, which often makes more sense in this workflow.\nprompt = PromptTemplate(\n template=\"Tell me a {adjective} joke about the day {date}\", \n input_variables=[\"adjective\"],\n partial_variables={\"date\": _get_datetime}\n);\nprint(prompt.format(adjective=\"funny\"))\nTell me a funny joke about the day 02/27/2023, 22:15:16\n Contents\n \nPartial With Strings\nPartial With Functions\nBy Harrison Chase\n \n \u00a9 Copyright 2023, Harrison Chase.\n \n Last updated on Mar 22, 2023.", "source": "https://langchain.readthedocs.io/en/latest/modules/prompts/examples/partial.html"} {"id": "eab1382e11f7-0", "text": ".ipynb\n.pdf\nExample Selectors\n Contents \nLengthBased ExampleSelector\nSimilarity ExampleSelector\nMaximal Marginal Relevance ExampleSelector\nNGram Overlap ExampleSelector\nExample Selectors#\nIf you have a large number of examples, you may need to select which ones to include in the prompt.

But many times you may want to get more structured information than just text back. This is where output parsers come in.\nOutput parsers are classes that help structure language model responses. There are two main methods an output parser must implement:\nget_format_instructions() -> str: A method which returns a string containing instructions for how the output of a language model should be formatted.\nparse(str) -> Any: A method which takes in a string (assumed to be the response from a language model) and parses it into some structure.\nAnd then one optional one:\nparse_with_prompt(str) -> Any: A method which takes in a string (assumed to be the response from a language model) and a prompt (assumed to the prompt that generated such a response) and parses it into some structure. The prompt is largely provided in the event the OutputParser wants to retry or fix the output in some way, and needs information from the prompt to do so.\nBelow we go over some examples of output parsers.\nfrom langchain.prompts import PromptTemplate, ChatPromptTemplate, HumanMessagePromptTemplate\nfrom langchain.llms import OpenAI\nfrom langchain.chat_models import ChatOpenAI\nPydanticOutputParser#\nThis output parser allows users to specify an arbitrary JSON schema and query LLMs for JSON outputs that conform to that schema.\nKeep in mind that large language models are leaky abstractions!

custom prompt templates needed?\nCreating a Custom Prompt Template\nUse the custom prompt template\nCreate a custom prompt template#\nLet\u2019s suppose we want the LLM to generate English language explanations of a function given its name. To achieve this task, we will create a custom prompt template that takes in the function name as input, and formats the prompt template to provide the source code of the function.\nWhy are custom prompt templates needed?#\nLangChain provides a set of default prompt templates that can be used to generate prompts for a variety of tasks. However, there may be cases where the default prompt templates do not meet your needs. For example, you may want to create a prompt template with specific dynamic instructions for your language model. In such cases, you can create a custom prompt template.\nTake a look at the current set of default prompt templates here.\nCreating a Custom Prompt Template#\nThere are essentially two distinct prompt templates available - string prompt templates and chat prompt templates. String prompt templates provides a simple prompt in string format, while chat prompt templates produces a more structured prompt to be used with a chat API.\nIn this guide, we will create a custom prompt using a string prompt template.\nTo create a custom string prompt template, there are two requirements:\nIt has an input_variables attribute that exposes what input variables the prompt template expects.\nIt exposes a format method that takes in keyword arguments corresponding to the expected input_variables and returns the formatted prompt.\nWe will create a custom prompt template that takes in the function name as input and formats the prompt to provide the source code of the function. To achieve this, let\u2019s first create a function that will return the source code of a function given its name.\nimport inspect\ndef get_source_code(function_name):\n # Get the source code of the function\n return inspect.getsource(function_name)", "source": "https://langchain.readthedocs.io/en/latest/modules/prompts/examples/custom_prompt_template.html"} {"id": "af991fe39863-1", "text": "# Get the source code of the function\n return inspect.getsource(function_name)\nNext, we\u2019ll create a custom prompt template that takes in the function name as input, and formats the prompt template to provide the source code of the function.\nfrom langchain.prompts import StringPromptTemplate\nfrom pydantic import BaseModel, validator\nclass FunctionExplainerPromptTemplate(StringPromptTemplate, BaseModel):\n \"\"\" A custom prompt template that takes in the function name as input, and formats the prompt template to provide the source code of the function. \"\"\"\n @validator(\"input_variables\")\n def validate_input_variables(cls, v):\n \"\"\" Validate that the input variables are correct. \"\"\"\n if len(v) != 1 or \"function_name\" not in v:\n raise ValueError(\"function_name must be the only input_variable.\")\n return v\n def format(self, **kwargs) -> str:\n # Get the source code of the function\n source_code = get_source_code(kwargs[\"function_name\"])\n # Generate the prompt to be sent to the language model\n prompt = f\"\"\"\n Given the function name and source code, generate an English language explanation of the function.\n Function Name: {kwargs[\"function_name\"].__name__}\n Source Code:\n {source_code}\n Explanation:\n \"\"\"\n return prompt\n \n def _prompt_type(self):\n return \"function-explainer\"\nUse the custom prompt template#\nNow that we have created a custom prompt template, we can use it to generate prompts for our task.\nfn_explainer = FunctionExplainerPromptTemplate(input_variables=[\"function_name\"])\n# Generate a prompt for the function \"get_source_code\"\nprompt = fn_explainer.format(function_name=get_source_code)\nprint(prompt)", "source": "https://langchain.readthedocs.io/en/latest/modules/prompts/examples/custom_prompt_template.html"} {"id": "af991fe39863-2", "text": "prompt = fn_explainer.format(function_name=get_source_code)\nprint(prompt)\n Given the function name and source code, generate an English language explanation of the function.\n Function Name: get_source_code\n Source Code:\n def get_source_code(function_name):\n # Get the source code of the function\n return inspect.getsource(function_name)\n Explanation:\n \nprevious\nHow-To Guides\nnext\nCreate a custom example selector\n Contents\n \nWhy are custom prompt templates needed?\nCreating a Custom Prompt Template\nUse the custom prompt template\nBy Harrison Chase\n \n \u00a9 Copyright 2023, Harrison Chase.\n \n Last updated on Mar 22, 2023.", "source": "https://langchain.readthedocs.io/en/latest/modules/prompts/examples/custom_prompt_template.html"} {"id": "2ae267bfd258-0", "text": ".md\n.pdf\nKey Concepts\n Contents \nDocument\nLoader\nUnstructured\nKey Concepts#\nDocument#\nThis class is a container for document information.

For example, the model trained on the News\nNavigator dataset [17] has been incorporated in the model hub.\nBeyond DL models, LayoutParser also promotes the sharing of entire doc-\nument digitization pipelines. For example, sometimes the pipeline requires the\ncombination of multiple DL models to achieve better accuracy. Currently, pipelines\nare mainly described in academic papers and implementations are often not pub-\nlicly available.

A subtype of this type of chain is the SimpleSequentialChain, where all subchains have only one input and one output,\nand the output of one is therefore used as sole input to the next chain.\nPrompt Selectors#\nOne thing that we\u2019ve noticed is that the best prompt to use is really dependent on the model you use.\nSome prompts work really good with some models, but not great with others.\nOne of our goals is provide good chains that \u201cjust work\u201d out of the box.\nA big part of chains like that is having prompts that \u201cjust work\u201d.\nSo rather than having a default prompt for chains, we are moving towards a paradigm where if a prompt is not explicitly\nprovided we select one with a PromptSelector. This class takes in the model passed in, and returns a default prompt.\nThe inner workings of the PromptSelector can look at any aspect of the model - LLM vs ChatModel, OpenAI vs Cohere, GPT3 vs GPT4, etc.\nDue to this being a newer feature, this may not be implemented for all chains, but this is the direction we are moving.\nprevious\nAsync API for Chain\nnext\nChains\n Contents\n \nChains\nSequential Chain\nPrompt Selectors\nBy Harrison Chase\n \n \u00a9 Copyright 2023, Harrison Chase.\n \n Last updated on Mar 22, 2023.", "source": "https://langchain.readthedocs.io/en/latest/modules/chains/key_concepts.html"} {"id": "d57d64d9234d-0", "text": ".rst\n.pdf\nHow-To Guides\nHow-To Guides#\nA chain is made up of links, which can be either primitives or other chains.\nPrimitives can be either prompts, llms, utils, or other chains.\nThe examples here are all end-to-end chains for specific applications.\nThey are broken up into three categories:\nGeneric Chains: Generic chains, that are meant to help build other chains rather than serve a particular purpose.\nUtility Chains: Chains consisting of an LLMChain interacting with a specific util.\nAsynchronous: Covering asynchronous functionality.\nIn addition to different types of chains, we also have the following how-to guides for working with chains in general:\nLoad From Hub: This notebook covers how to load chains from LangChainHub.\nprevious\nGetting Started\nnext\nGeneric Chains\nBy Harrison Chase\n \n \u00a9 Copyright 2023, Harrison Chase.\n \n Last updated on Mar 22, 2023.", "source": "https://langchain.readthedocs.io/en/latest/modules/chains/how_to_guides.html"} {"id": "d197a81a4053-0", "text": ".rst\n.pdf\nUtility Chains\nUtility Chains#\nA chain is made up of links, which can be either primitives or other chains.\nPrimitives can be either prompts, llms, utils, or other chains.\nThe examples here are all end-to-end chains for specific applications, focused on interacting an LLMChain with a specific utility.\nLLMMath\nLinks Used: Python REPL, LLMChain\nNotes: This chain takes user input (a math question), uses an LLMChain to convert it to python code snippet to run in the Python REPL, and then returns that as the result.\nExample Notebook\nPAL\nLinks Used: Python REPL, LLMChain\nNotes: This chain takes user input (a reasoning question), uses an LLMChain to convert it to python code snippet to run in the Python REPL, and then returns that as the result.\nPaper\nExample Notebook\nSQLDatabase Chain\nLinks Used: SQLDatabase, LLMChain\nNotes: This chain takes user input (a question), uses a first LLM chain to construct a SQL query to run against the SQL database, and then uses another LLMChain to take the results of that query and use it to answer the original question.\nExample Notebook\nAPI Chain\nLinks Used: LLMChain, Requests\nNotes: This chain first uses a LLM to construct the url to hit, then makes that request with the Requests wrapper, and finally runs that result through the language model again in order to product a natural language response.\nExample Notebook\nLLMBash Chain\nLinks Used: BashProcess, LLMChain\nNotes: This chain takes user input (a question), uses an LLM chain to convert it to a bash command to run in the terminal, and then returns that as the result.\nExample Notebook\nLLMChecker Chain\nLinks Used: LLMChain", "source": "https://langchain.readthedocs.io/en/latest/modules/chains/utility_how_to.html"} {"id": "d197a81a4053-1", "text": "Example Notebook\nLLMChecker Chain\nLinks Used: LLMChain\nNotes: This chain takes user input (a question), uses an LLM chain to answer that question, and then uses other LLMChains to self-check that answer.\nExample Notebook\nLLMRequests Chain\nLinks Used: Requests, LLMChain\nNotes: This chain takes a URL and other inputs, uses Requests to get the data at that URL, and then passes that along with the other inputs into an LLMChain to generate a response.

We will learn how to create a chain, add components to it, and run it.\nIn this tutorial, we will cover:\nUsing a simple LLM chain\nCreating sequential chains\nCreating a custom chain\nWhy do we need chains?#\nChains allow us to combine multiple components together to create a single, coherent application. For example, we can create a chain that takes user input, formats it with a PromptTemplate, and then passes the formatted response to an LLM. We can build more complex chains by combining multiple chains together, or by combining chains with other components.\nQuery an LLM with the LLMChain#\nThe LLMChain is a simple chain that takes in a prompt template, formats it with the user input and returns the response from an LLM.\nTo use the LLMChain, first create a prompt template.\nfrom langchain.prompts import PromptTemplate\nfrom langchain.llms import OpenAI\nllm = OpenAI(temperature=0.9)\nprompt = PromptTemplate(\n input_variables=[\"product\"],\n template=\"What is a good name for a company that makes {product}?\",\n)\nWe can now create a very simple chain that will take user input, format the prompt with it, and then send it to the LLM.\nfrom langchain.chains import LLMChain\nchain = LLMChain(llm=llm, prompt=prompt)\n# Run the chain only specifying the input variable.\nprint(chain.run(\"colorful socks\"))\nRainbow Socks Co.", "source": "https://langchain.readthedocs.io/en/latest/modules/chains/getting_started.html"} {"id": "e6adc41d17b7-1", "text": "print(chain.run(\"colorful socks\"))\nRainbow Socks Co.\nYou can use a chat model in an LLMChain as well:\nfrom langchain.chat_models import ChatOpenAI\nfrom langchain.prompts.chat import (\n ChatPromptTemplate,\n HumanMessagePromptTemplate,\n)\nhuman_message_prompt = HumanMessagePromptTemplate(\n prompt=PromptTemplate(\n template=\"What is a good name for a company that makes {product}?\",\n input_variables=[\"product\"],\n )\n )\nchat_prompt_template = ChatPromptTemplate.from_messages([human_message_prompt])\nchat = ChatOpenAI(temperature=0.9)\nchain = LLMChain(llm=chat, prompt=chat_prompt_template)\nprint(chain.run(\"colorful socks\"))\nRainbow Threads\nThis is one of the simpler types of chains, but understanding how it works will set you up well for working with more complex chains.\nCombine chains with the SequentialChain#\nThe next step after calling a language model is to make a series of calls to a language model. We can do this using sequential chains, which are chains that execute their links in a predefined order. Specifically, we will use the SimpleSequentialChain. This is the simplest type of a sequential chain, where each step has a single input/output, and the output of one step is the input to the next.\nIn this tutorial, our sequential chain will:\nFirst, create a company name for a product.

Moderation chains are useful for detecting text that could be hateful, violent, etc. This can be useful to apply on both user input, but also on the output of a Language Model. Some API providers, like OpenAI, specifically prohibit you, or your end users, from generating some types of harmful content. To comply with this (and to just generally prevent your application from being harmful) you may often want to append a moderation chain to any LLMChains, in order to make sure any output the LLM generates is not harmful.\nIf the content passed into the moderation chain is harmful, there is not one best way to handle it, it probably depends on your application. Sometimes you may want to throw an error in the Chain (and have your application handle that). Other times, you may want to return something to the user explaining that the text was harmful. There could even be other ways to handle it! We will cover all these ways in this notebook.\nIn this notebook, we will show:\nHow to run any piece of text through a moderation chain.\nHow to append a Moderation chain to a LLMChain.\nfrom langchain.llms import OpenAI\nfrom langchain.chains import OpenAIModerationChain, SequentialChain, LLMChain, SimpleSequentialChain\nfrom langchain.prompts import PromptTemplate\nHow to use the moderation chain#\nHere\u2019s an example of using the moderation chain with default settings (will return a string explaining stuff was flagged).\nmoderation_chain = OpenAIModerationChain()\nmoderation_chain.run(\"This is okay\")\n'This is okay'\nmoderation_chain.run(\"I will kill you\")", "source": "https://langchain.readthedocs.io/en/latest/modules/chains/examples/moderation.html"} {"id": "d78e22b0d39c-1", "text": "'This is okay'\nmoderation_chain.run(\"I will kill you\")\n\"Text was found that violates OpenAI's content policy.\"\nHere\u2019s an example of using the moderation chain to throw an error.\nmoderation_chain_error = OpenAIModerationChain(error=True)\nmoderation_chain_error.run(\"This is okay\")\n'This is okay'\nmoderation_chain_error.run(\"I will kill you\")\n---------------------------------------------------------------------------\nValueError Traceback (most recent call last)\nCell In[7], line 1\n----> 1 moderation_chain_error.run(\"I will kill you\")\nFile ~/workplace/langchain/langchain/chains/base.py:138, in Chain.run(self, *args, **kwargs)\n 136 if len(args) != 1:\n 137 raise ValueError(\"`run` supports only one positional argument.\")\n--> 138 return self(args[0])[self.output_keys[0]]\n 140 if kwargs and not args:\n 141 return self(kwargs)[self.output_keys[0]]\nFile ~/workplace/langchain/langchain/chains/base.py:112, in Chain.__call__(self, inputs, return_only_outputs)\n 108 if self.verbose:\n 109 print(\n 110 f\"\\n\\n\\033[1m> Entering new {self.__class__.__name__} chain...\\033[0m\"\n 111 )\n--> 112 outputs = self._call(inputs)\n 113 if self.verbose:\n 114 print(f\"\\n\\033[1m> Finished {self.__class__.__name__} chain.\\033[0m\")\nFile ~/workplace/langchain/langchain/chains/moderation.py:81, in OpenAIModerationChain._call(self, inputs)\n 79 text = inputs[self.input_key]", "source": "https://langchain.readthedocs.io/en/latest/modules/chains/examples/moderation.html"} {"id": "d78e22b0d39c-2", "text": "79 text = inputs[self.input_key]\n 80 results = self.client.create(text)\n---> 81 output = self._moderate(text, results[\"results\"][0])\n 82 return {self.output_key: output}\nFile ~/workplace/langchain/langchain/chains/moderation.py:73, in OpenAIModerationChain._moderate(self, text, results)\n 71 error_str = \"Text was found that violates OpenAI's content policy.\"\n 72 if self.error:\n---> 73 raise ValueError(error_str)\n 74 else:\n 75 return error_str\nValueError: Text was found that violates OpenAI's content policy.\nHere\u2019s an example of creating a custom moderation chain with a custom error message.

It has a few distinct differences from the LLMCheckerChain, in that it doesn\u2019t have any assumtions to the format of the input text (or summary).\nAdditionally, as the LLMs like to hallucinate when fact checking or get confused by context, it is sometimes beneficial to run the checker multiple times. It does this by feeding the rewritten \u201cTrue\u201d result back on itself, and checking the \u201cfacts\u201d for truth. As you can see from the examples below, this can be very effective in arriving at a generally true body of text.\nYou can control the number of times the checker runs by setting the max_checks parameter.

This can be done with the .save method, and specifying a file path with a json or yaml extension.\nfrom langchain import PromptTemplate, OpenAI, LLMChain\ntemplate = \"\"\"Question: {question}\nAnswer: Let's think step by step.\"\"\"\nprompt = PromptTemplate(template=template, input_variables=[\"question\"])\nllm_chain = LLMChain(prompt=prompt, llm=OpenAI(temperature=0), verbose=True)\nllm_chain.save(\"llm_chain.json\")\nLet\u2019s now take a look at what\u2019s inside this saved file\n!cat llm_chain.json\n{\n \"memory\": null,\n \"verbose\": true,\n \"prompt\": {\n \"input_variables\": [\n \"question\"\n ],\n \"output_parser\": null,\n \"template\": \"Question: {question}\\n\\nAnswer: Let's think step by step.\",\n \"template_format\": \"f-string\"\n },\n \"llm\": {\n \"model_name\": \"text-davinci-003\",\n \"temperature\": 0.0,\n \"max_tokens\": 256,\n \"top_p\": 1,\n \"frequency_penalty\": 0,\n \"presence_penalty\": 0,\n \"n\": 1,\n \"best_of\": 1,\n \"request_timeout\": null,", "source": "https://langchain.readthedocs.io/en/latest/modules/chains/generic/serialization.html"} {"id": "8cb86c0c5032-1", "text": "\"best_of\": 1,\n \"request_timeout\": null,\n \"logit_bias\": {},\n \"_type\": \"openai\"\n },\n \"output_key\": \"text\",\n \"_type\": \"llm_chain\"\n}\nLoading a chain from disk#\nWe can load a chain from disk by using the load_chain method.\nfrom langchain.chains import load_chain\nchain = load_chain(\"llm_chain.json\")\nchain.run(\"whats 2 + 2\")\n> Entering new LLMChain chain...\nPrompt after formatting:\nQuestion: whats 2 + 2\nAnswer: Let's think step by step.\n> Finished chain.\n' 2 + 2 = 4'\nSaving components separately#\nIn the above example, we can see that the prompt and llm configuration information is saved in the same json as the overall chain. Alternatively, we can split them up and save them separately. This is often useful to make the saved components more modular. In order to do this, we just need to specify llm_path instead of the llm component, and prompt_path instead of the prompt component.\nllm_chain.prompt.save(\"prompt.json\")\n!cat prompt.json\n{\n \"input_variables\": [\n \"question\"\n ],\n \"output_parser\": null,\n \"template\": \"Question: {question}\\n\\nAnswer: Let's think step by step.\",\n \"template_format\": \"f-string\"\n}\nllm_chain.llm.save(\"llm.json\")\n!cat llm.json\n{\n \"model_name\": \"text-davinci-003\",\n \"temperature\": 0.0,\n \"max_tokens\": 256,\n \"top_p\": 1,\n \"frequency_penalty\": 0,", "source": "https://langchain.readthedocs.io/en/latest/modules/chains/generic/serialization.html"} {"id": "8cb86c0c5032-2", "text": "\"top_p\": 1,\n \"frequency_penalty\": 0,\n \"presence_penalty\": 0,\n \"n\": 1,\n \"best_of\": 1,\n \"request_timeout\": null,\n \"logit_bias\": {},\n \"_type\": \"openai\"\n}\nconfig = {\n \"memory\": None,\n \"verbose\": True,\n \"prompt_path\": \"prompt.json\",\n \"llm_path\": \"llm.json\",\n \"output_key\": \"text\",\n \"_type\": \"llm_chain\"\n}\nimport json\nwith open(\"llm_chain_separate.json\", \"w\") as f:\n json.dump(config, f, indent=2)\n!cat llm_chain_separate.json\n{\n \"memory\": null,\n \"verbose\": true,\n \"prompt_path\": \"prompt.json\",\n \"llm_path\": \"llm.json\",\n \"output_key\": \"text\",\n \"_type\": \"llm_chain\"\n}\nWe can then load it in the same way\nchain = load_chain(\"llm_chain_separate.json\")\nchain.run(\"whats 2 + 2\")\n> Entering new LLMChain chain...\nPrompt after formatting:\nQuestion: whats 2 + 2\nAnswer: Let's think step by step.\n> Finished chain.\n' 2 + 2 = 4'\nprevious\nSequential Chains\nnext\nTransformation Chain\n Contents\n \nSaving a chain to disk\nLoading a chain from disk\nSaving components separately\nBy Harrison Chase\n \n \u00a9 Copyright 2023, Harrison Chase.\n \n Last updated on Mar 22, 2023.", "source": "https://langchain.readthedocs.io/en/latest/modules/chains/generic/serialization.html"} {"id": "e8cad34e8972-0", "text": ".ipynb\n.pdf\nTransformation Chain\nTransformation Chain#\nThis notebook showcases using a generic transformation chain.\nAs an example, we will create a dummy transformation that takes in a super long text, filters the text to only the first 3 paragraphs, and then passes that into an LLMChain to summarize those.\nfrom langchain.chains import TransformChain, LLMChain, SimpleSequentialChain\nfrom langchain.llms import OpenAI\nfrom langchain.prompts import PromptTemplate\nwith open('../../state_of_the_union.txt') as f:\n state_of_the_union = f.read()\ndef transform_func(inputs: dict) -> dict:\n text = inputs[\"text\"]\n shortened_text = \"\\n\\n\".join(text.split(\"\\n\\n\")[:3])\n return {\"output_text\": shortened_text}\ntransform_chain = TransformChain(input_variables=[\"text\"], output_variables=[\"output_text\"], transform=transform_func)\ntemplate = \"\"\"Summarize this text:\n{output_text}\nSummary:\"\"\"\nprompt = PromptTemplate(input_variables=[\"output_text\"], template=template)\nllm_chain = LLMChain(llm=OpenAI(), prompt=prompt)\nsequential_chain = SimpleSequentialChain(chains=[transform_chain, llm_chain])\nsequential_chain.run(state_of_the_union)\n' The speaker addresses the nation, noting that while last year they were kept apart due to COVID-19, this year they are together again.

This is particularly useful when you want to take the output from one call and use it as the input to another.\nIn this notebook we will walk through some examples for how to do this, using sequential chains. Sequential chains are defined as a series of chains, called in deterministic order. There are two types of sequential chains:\nSimpleSequentialChain: The simplest form of sequential chains, where each step has a singular input/output, and the output of one step is the input to the next.\nSequentialChain: A more general form of sequential chains, allowing for multiple inputs/outputs.\nSimpleSequentialChain#\nIn this series of chains, each individual chain has a single input and a single output, and the output of one step is used as input to the next.\nLet\u2019s walk through a toy example of doing this, where the first chain takes in the title of an imaginary play and then generates a synopsis for that title, and the second chain takes in the synopsis of that play and generates an imaginary review for that play.\n%load_ext dotenv\n%dotenv\ncannot find .env file\nfrom langchain.llms import OpenAI\nfrom langchain.chains import LLMChain\nfrom langchain.prompts import PromptTemplate\n# This is an LLMChain to write a synopsis given a title of a play.\nllm = OpenAI(temperature=.7)\ntemplate = \"\"\"You are a playwright.

In this next example, we will experiment with more complex chains that involve multiple inputs, and where there also multiple final outputs.\nOf particular importance is how we name the input/output variable names. In the above example we didn\u2019t have to think about that because we were just passing the output of one chain directly as input to the next, but here we do have worry about that because we have multiple inputs.\n# This is an LLMChain to write a synopsis given a title of a play and the era it is set in.\nllm = OpenAI(temperature=.7)\ntemplate = \"\"\"You are a playwright.

How is this index getting created?\nA lot of the magic is being hid in this VectorstoreIndexCreator. What is this doing?\nThere are three main steps going on after the documents are loaded:\nSplitting documents into chunks\nCreating embeddings for each document\nStoring documents and embeddings in a vectorstore\nLet\u2019s walk through this in code\ndocuments = loader.load()\nNext, we will split the documents into chunks.", "source": "https://langchain.readthedocs.io/en/latest/modules/indexes/getting_started.html"} {"id": "1795792d35ec-2", "text": "documents = loader.load()\nNext, we will split the documents into chunks.\nfrom langchain.text_splitter import CharacterTextSplitter\ntext_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)\ntexts = text_splitter.split_documents(documents)\nWe will then select which embeddings we want to use.\nfrom langchain.embeddings import OpenAIEmbeddings\nembeddings = OpenAIEmbeddings()\nWe now create the vectorstore to use as the index.\nfrom langchain.vectorstores import Chroma\ndb = Chroma.from_documents(texts, embeddings)\nRunning Chroma using direct local API.\nUsing DuckDB in-memory for database.

LangChain supports four of the more common ones - and\nwe are actively looking to include more, so if you have any ideas please reach out! Note that there is not\none best method - the decision of which one to use is often very context specific. In order from simplest to\nmost complex:\nStuffing#\nStuffing is the simplest method, whereby you simply stuff all the related data into the prompt as context\nto pass to the language model. This is implemented in LangChain as the StuffDocumentsChain.\nPros: Only makes a single call to the LLM. When generating text, the LLM has access to all the data at once.\nCons: Most LLMs have a context length, and for large documents (or many documents) this will not work as it will result in a prompt larger than the context length.\nThe main downside of this method is that it only works on smaller pieces of data. Once you are working\nwith many pieces of data, this approach is no longer feasible. The next two approaches are designed to help deal with that.\nMap Reduce#\nThis method involves running an initial prompt on each chunk of data (for summarization tasks, this", "source": "https://langchain.readthedocs.io/en/latest/modules/indexes/combine_docs.html"} {"id": "3b75d7ce3247-1", "text": "This method involves running an initial prompt on each chunk of data (for summarization tasks, this\ncould be a summary of that chunk; for question-answering tasks, it could be an answer based solely on that chunk).\nThen a different prompt is run to combine all the initial outputs. This is implemented in the LangChain as the MapReduceDocumentsChain.\nPros: Can scale to larger documents (and more documents) than StuffDocumentsChain. The calls to the LLM on individual documents are independent and can therefore be parallelized.\nCons: Requires many more calls to the LLM than StuffDocumentsChain. Loses some information during the final combined call.\nRefine#\nThis method involves running an initial prompt on the first chunk of data, generating some output.\nFor the remaining documents, that output is passed in, along with the next document,\nasking the LLM to refine the output based on the new document.\nPros: Can pull in more relevant context, and may be less lossy than MapReduceDocumentsChain.\nCons: Requires many more calls to the LLM than StuffDocumentsChain. The calls are also NOT independent, meaning they cannot be paralleled like MapReduceDocumentsChain. There is also some potential dependencies on the ordering of the documents.\nMap-Rerank#\nThis method involves running an initial prompt on each chunk of data, that not only tries to complete a\ntask but also gives a score for how certain it is in its answer. The responses are then\nranked according to this score, and the highest score is returned.\nPros: Similar pros as MapReduceDocumentsChain. Requires fewer calls, compared to MapReduceDocumentsChain.\nCons: Cannot combine information between documents. This means it is most useful when you expect there to be a single simple answer in a single document.\n Contents\n \nStuffing\nMap Reduce\nRefine\nMap-Rerank\nBy Harrison Chase", "source": "https://langchain.readthedocs.io/en/latest/modules/indexes/combine_docs.html"} {"id": "3b75d7ce3247-2", "text": "Stuffing\nMap Reduce\nRefine\nMap-Rerank\nBy Harrison Chase\n \n \u00a9 Copyright 2023, Harrison Chase.\n \n Last updated on Mar 22, 2023.", "source": "https://langchain.readthedocs.io/en/latest/modules/indexes/combine_docs.html"} {"id": "7573557c0053-0", "text": ".ipynb\n.pdf\nFAISS\n Contents \nSimilarity Search with score\nSaving and loading\nMerging\nFAISS#\nThis notebook shows how to use functionality related to the FAISS vector database.\nfrom langchain.embeddings.openai import OpenAIEmbeddings\nfrom langchain.text_splitter import CharacterTextSplitter\nfrom langchain.vectorstores import FAISS\nfrom langchain.document_loaders import TextLoader\nfrom langchain.document_loaders import TextLoader\nloader = TextLoader('../../state_of_the_union.txt')\ndocuments = loader.load()\ntext_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)\ndocs = text_splitter.split_documents(documents)\nembeddings = OpenAIEmbeddings()\ndb = FAISS.from_documents(docs, embeddings)\nquery = \"What did the president say about Ketanji Brown Jackson\"\ndocs = db.similarity_search(query)\nprint(docs[0].page_content)\nTonight.

By default, the HyDE class comes with some default prompts to use (see the paper for more details on them), but we can also create our own.\nfrom langchain.llms import OpenAI\nfrom langchain.embeddings import OpenAIEmbeddings\nfrom langchain.chains import LLMChain, HypotheticalDocumentEmbedder\nfrom langchain.prompts import PromptTemplate\nbase_embeddings = OpenAIEmbeddings()\nllm = OpenAI()\n# Load with `web_search` prompt\nembeddings = HypotheticalDocumentEmbedder.from_llm(llm, base_embeddings, \"web_search\")\n# Now we can use it as any embedding class!\nresult = embeddings.embed_query(\"Where is the Taj Mahal?\")\nMultiple generations#\nWe can also generate multiple documents and then combine the embeddings for those.

In recent years, LLMs have made significant advances in a variety of natural language processing tasks, including language translation, text generation, and sentiment analysis.\n\\subsection{History of LLMs}\nThe earliest LLMs were developed in the 1980s and 1990s, but they were limited by the amount of data that could be processed and the computational power available at the time. In the past decade, however, advances in hardware and software have made it possible to train LLMs on massive datasets, leading to significant improvements in performance.\n\\subsection{Applications of LLMs}\nLLMs have many applications in industry, including chatbots, content creation, and virtual assistants. They can also be used in academia for research in linguistics, psychology, and computational linguistics.\n\\end{document}\n\"\"\"\nlatex_splitter = LatexTextSplitter(chunk_size=400, chunk_overlap=0)\ndocs = latex_splitter.create_documents([latex_text])\ndocs\nPython Code Text Splitter#\nPythonCodeTextSplitter splits text along python class and method definitions.

There are lots of Embedding providers (OpenAI, Cohere, Hugging Face, etc) - this class is designed to provide a standard interface for all of them.\nEmbeddings create a vector representation of a piece of text. This is useful because it means we can think about text in the vector space, and do things like semantic search where we look for pieces of text that are most similar in the vector space.\nThe base Embedding class in LangChain exposes two methods: embed_documents and embed_query. The largest difference is that these two methods have different interfaces: one works over multiple documents, while the other works over a single document. Besides this, another reason for having these as two separate methods is that some embedding providers have different embedding methods for documents (to be searched over) vs queries (the search query itself).\nOpenAI#\nLet\u2019s load the OpenAI Embedding class.\nfrom langchain.embeddings import OpenAIEmbeddings\nembeddings = OpenAIEmbeddings()\ntext = \"This is a test document.\"\nquery_result = embeddings.embed_query(text)\ndoc_result = embeddings.embed_documents([text])\nLet\u2019s load the OpenAI Embedding class with first generation models (e.g. text-search-ada-doc-001/text-search-ada-query-001).

For a more detailed walkthrough of these types, please see this notebook.\nThere are two ways to load different chain types. First, you can specify the chain type argument in the from_chain_type method. This allows you to pass in the name of the chain type you want to use. For example, in the below we change the chain type to map_reduce.\nchain = VectorDBQAWithSourcesChain.from_chain_type(OpenAI(temperature=0), chain_type=\"map_reduce\", vectorstore=docsearch)\nchain({\"question\": \"What did the president say about Justice Breyer\"}, return_only_outputs=True)\n{'answer': ' The president honored Justice Stephen Breyer for his service.\\n',\n 'sources': '30-pl'}\nThe above way allows you to really simply change the chain_type, but it does provide a ton of flexibility over parameters to that chain type. If you want to control those parameters, you can load the chain directly (as you did in this notebook) and then pass that directly to the the VectorDBQA chain with the combine_documents_chain parameter. For example:\nfrom langchain.chains.qa_with_sources import load_qa_with_sources_chain\nqa_chain = load_qa_with_sources_chain(OpenAI(temperature=0), chain_type=\"stuff\")\nqa = VectorDBQAWithSourcesChain(combine_documents_chain=qa_chain, vectorstore=docsearch)\nqa({\"question\": \"What did the president say about Justice Breyer\"}, return_only_outputs=True)\n{'answer': ' The president honored Justice Stephen Breyer for his service.\\n',\n 'sources': '30-pl'}\nprevious\nVector DB Question/Answering\nnext\nVector DB Text Generation\n Contents\n \nChain Type\nBy Harrison Chase", "source": "https://langchain.readthedocs.io/en/latest/modules/indexes/chain_examples/vector_db_qa_with_sources.html"} {"id": "95c4f7c73985-2", "text": "next\nVector DB Text Generation\n Contents\n \nChain Type\nBy Harrison Chase\n \n \u00a9 Copyright 2023, Harrison Chase.\n \n Last updated on Mar 22, 2023.", "source": "https://langchain.readthedocs.io/en/latest/modules/indexes/chain_examples/vector_db_qa_with_sources.html"} {"id": "b6792bab5f8e-0", "text": ".ipynb\n.pdf\nChat Vector DB\n Contents \nReturn Source Documents\nChat Vector DB with search_distance\nChat Vector DB with map_reduce\nChat Vector DB with Question Answering with sources\nChat Vector DB with streaming to stdout\nget_chat_history Function\nChat Vector DB#\nThis notebook goes over how to set up a chain to chat with a vector database.

Language Model Application\nQuickstart Guide#\nThis tutorial gives you a quick walkthrough about building an end-to-end language model application with LangChain.\nInstallation#\nTo get started, install LangChain with the following command:\npip install langchain\nEnvironment Setup#\nUsing LangChain will usually require integrations with one or more model providers, data stores, apis, etc.\nFor this example, we will be using OpenAI\u2019s APIs, so we will first need to install their SDK:\npip install openai\nWe will then need to set the environment variable in the terminal.\nexport OPENAI_API_KEY=\"...\"\nAlternatively, you could do this from inside the Jupyter notebook (or Python script):\nimport os\nos.environ[\"OPENAI_API_KEY\"] = \"...\"\nBuilding a Language Model Application#\nNow that we have installed LangChain and set up our environment, we can start building our language model application.\nLangChain provides many modules that can be used to build language model applications. Modules can be combined to create more complex applications, or be used individually for simple applications.\nLLMs: Get predictions from a language model\nThe most basic building block of LangChain is calling an LLM on some input.\nLet\u2019s walk through a simple example of how to do this.\nFor this purpose, let\u2019s pretend we are building a service that generates a company name based on what the company makes.\nIn order to do this, we first need to import the LLM wrapper.\nfrom langchain.llms import OpenAI\nWe can then initialize the wrapper with any arguments.\nIn this example, we probably want the outputs to be MORE random, so we\u2019ll initialize it with a HIGH temperature.\nllm = OpenAI(temperature=0.9)\nWe can now call it on some input!", "source": "https://langchain.readthedocs.io/en/latest/getting_started/getting_started.html"} {"id": "f7dce668e0ea-1", "text": "We can now call it on some input!\ntext = \"What would be a good company name for a company that makes colorful socks?\"\nprint(llm(text))\nFeetful of Fun\nFor more details on how to use LLMs within LangChain, see the LLM getting started guide.\nPrompt Templates: Manage prompts for LLMs\nCalling an LLM is a great first step, but it\u2019s just the beginning.\nNormally when you use an LLM in an application, you are not sending user input directly to the LLM.\nInstead, you are probably taking user input and constructing a prompt, and then sending that to the LLM.\nFor example, in the previous example, the text we passed in was hardcoded to ask for a name for a company that made colorful socks.\nIn this imaginary service, what we would want to do is take only the user input describing what the company does, and then format the prompt with that information.\nThis is easy to do with LangChain!\nFirst lets define the prompt template:\nfrom langchain.prompts import PromptTemplate\nprompt = PromptTemplate(\n input_variables=[\"product\"],\n template=\"What is a good name for a company that makes {product}?\",\n)\nLet\u2019s now see how this works! We can call the .format method to format it.\nprint(prompt.format(product=\"colorful socks\"))\nWhat is a good name for a company that makes colorful socks?\nFor more details, check out the getting started guide for prompts.\nChains: Combine LLMs and prompts in multi-step workflows\nUp until now, we\u2019ve worked with the PromptTemplate and LLM primitives by themselves. But of course, a real application is not just one primitive, but rather a combination of them.\nA chain in LangChain is made up of links, which can be either primitives like LLMs or other chains.", "source": "https://langchain.readthedocs.io/en/latest/getting_started/getting_started.html"} {"id": "f7dce668e0ea-2", "text": "The most core type of chain is an LLMChain, which consists of a PromptTemplate and an LLM.\nExtending the previous example, we can construct an LLMChain which takes user input, formats it with a PromptTemplate, and then passes the formatted response to an LLM.\nfrom langchain.prompts import PromptTemplate\nfrom langchain.llms import OpenAI\nllm = OpenAI(temperature=0.9)\nprompt = PromptTemplate(\n input_variables=[\"product\"],\n template=\"What is a good name for a company that makes {product}?\",\n)\nWe can now create a very simple chain that will take user input, format the prompt with it, and then send it to the LLM:\nfrom langchain.chains import LLMChain\nchain = LLMChain(llm=llm, prompt=prompt)\nNow we can run that chain only specifying the product!\nchain.run(\"colorful socks\")\n# -> '\\n\\nSocktastic!'\nThere we go! There\u2019s the first chain - an LLM Chain.\nThis is one of the simpler types of chains, but understanding how it works will set you up well for working with more complex chains.\nFor more details, check out the getting started guide for chains.\nAgents: Dynamically call chains based on user input\nSo far the chains we\u2019ve looked at run in a predetermined order.\nAgents no longer do: they use an LLM to determine which actions to take and in what order. An action can either be using a tool and observing its output, or returning to the user.\nWhen used correctly agents can be extremely powerful. In this tutorial, we show you how to easily use agents through the simplest, highest level API.\nIn order to load agents, you should understand the following concepts:", "source": "https://langchain.readthedocs.io/en/latest/getting_started/getting_started.html"} {"id": "f7dce668e0ea-3", "text": "In order to load agents, you should understand the following concepts:\nTool: A function that performs a specific duty.

This should be a string that references a support agent class. Because this notebook focuses on the simplest, highest level API, this only covers using the standard supported agents. If you want to implement a custom agent, see the documentation for custom agents (coming soon).\nAgents: For a list of supported agents and their specifications, see here.\nTools: For a list of predefined tools and their specifications, see here.\nFor this example, you will also need to install the SerpAPI Python package.\npip install google-search-results\nAnd set the appropriate environment variables.\nimport os\nos.environ[\"SERPAPI_API_KEY\"] = \"...\"\nNow we can get started!\nfrom langchain.agents import load_tools\nfrom langchain.agents import initialize_agent\nfrom langchain.llms import OpenAI\n# First, let's load the language model we're going to use to control the agent.\nllm = OpenAI(temperature=0)\n# Next, let's load some tools to use.

But often, you may want a chain or agent to have some concept of \u201cmemory\u201d so that it may remember information about its previous interactions. The clearest and simple example of this is when designing a chatbot - you want it to remember previous messages so it can use context from that to have a better conversation. This would be a type of \u201cshort-term memory\u201d. On the more complex side, you could imagine a chain/agent remembering key pieces of information over time - this would be a form of \u201clong-term memory\u201d. For more concrete ideas on the latter, see this awesome paper.\nLangChain provides several specially created chains just for this purpose. This notebook walks through using one of those chains (the ConversationChain) with two different types of memory.\nBy default, the ConversationChain has a simple type of memory that remembers all previous inputs/outputs and adds them to the context that is passed. Let\u2019s take a look at using this chain (setting verbose=True so we can see the prompt).\nfrom langchain import OpenAI, ConversationChain\nllm = OpenAI(temperature=0)\nconversation = ConversationChain(llm=llm, verbose=True)\nconversation.predict(input=\"Hi there!\")\n> Entering new chain...\nPrompt after formatting:\nThe following is a friendly conversation between a human and an AI.
