### System Prompt Handling

We appreciate the feedback received from our community regarding our system prompt handling.  
In response, we have implemented stronger support for system prompts.  
To achieve optimal results, we recommend always including a system prompt that clearly outlines the bot's purpose, even if it is minimal.

### Basic Instruct Template (V7)

```
<s>[SYSTEM_PROMPT] <system prompt>[/SYSTEM_PROMPT][INST] <user message>[/INST] <assistant response></s>[INST] <user message>[/INST]
```

**Be careful with subtle missing or trailing white spaces!**

*Please make sure to use [mistral-common](https://github.com/mistralai/mistral-common) as the source of truth*

## Usage

The model can be used with the following frameworks

- [`vllm`](https://github.com/vllm-project/vllm): See [here](#vLLM)
  
### vLLM

We recommend using Pixtral-Large-Instruct-2411 with the [vLLM library](https://github.com/vllm-project/vllm)
to implement production-ready inference pipelines with Pixtral-Large-Instruct-2411.

**_Installation_**

Make sure you install [`vLLM >= v0.6.4.post1`](https://github.com/vllm-project/vllm/releases/tag/v0.6.4.post1):

```
pip install --upgrade vllm
```

Also make sure you have [`mistral_common >= 1.5.0`](https://github.com/mistralai/mistral-common/releases/tag/v1.5.0) installed:

```
pip install --upgrade mistral_common
```

You can also make use of a ready-to-go [docker image](https://github.com/vllm-project/vllm/blob/main/Dockerfile) or on the [docker hub](https://hub.docker.com/layers/vllm/vllm-openai/latest/images/sha256-55a88146a4da0b6e193431b5b1d3492dfd7bebdc16919df4d031273e85a6157c?context=explore).


#### Server (Image)
We recommend to use Pixtral-Large-Instruct-2411 in a server/client setting. 

1. Spin up a server:

```
vllm serve mistralai/Pixtral-Large-Instruct-2411 --tokenizer_mode mistral --limit_mm_per_prompt 'image=10' --tensor-parallel-size 8
```

2. And ping the client:

```py
import requests
import json
from huggingface_hub import hf_hub_download
from datetime import datetime, timedelta

url = "http://<your-server-url>:8000/v1/chat/completions"
headers = {"Content-Type": "application/json", "Authorization": "Bearer token"}

model = "mistralai/Pixtral-Large-Instruct-2411"


def load_system_prompt(repo_id: str, filename: str) -> str:
    file_path = hf_hub_download(repo_id=repo_id, filename=filename)
    with open(file_path, "r") as file:
        system_prompt = file.read()
    today = datetime.today().strftime("%Y-%m-%d")
    yesterday = (datetime.today() - timedelta(days=1)).strftime("%Y-%m-%d")
    model_name = repo_id.split("/")[-1]
    return system_prompt.format(name=model_name, today=today, yesterday=yesterday)


SYSTEM_PROMPT = load_system_prompt(model, "SYSTEM_PROMPT.txt")

image_url = "https://huggingface.co/datasets/patrickvonplaten/random_img/resolve/main/europe.png"

messages = [
    {"role": "system", "content": SYSTEM_PROMPT},
    {
        "role": "user",
        "content": [
            {
                "type": "text",
                "text": "Which of the depicted countries has the best food? Which the second and third and fourth? Name the country, its color on the map and one its city that is visible on the map, but is not the capital. Make absolutely sure to only name a city that can be seen on the map.",
            },
            {"type": "image_url", "image_url": {"url": image_url}},
        ],
    },
]

data = {"model": model, "messages": messages}

response = requests.post(url, headers=headers, data=json.dumps(data))
print(response.json()["choices"][0]["message"]["content"])
# Determining which country has the "best" food can be subjective and depends on personal preferences. However, based on popular culinary reputations, here are some countries known for their cuisine:

#1. **Italy** (Brown) - Known for its pasta, pizza, and diverse regional dishes.
#   - City: Milan

#2. **France** (Dark Brown) - Renowned for its fine dining, pastries, and wine.
#   - City: Lyon

#3. **Spain** (Yellow) - Famous for tapas, paella, and a variety of seafood dishes.
#   - City: Barcelona

#4. **Greece** (Yellow) - Known for its Mediterranean cuisine, including moussaka, souvlaki, and fresh seafood.
#   - City: Thessaloniki

#These rankings are based on general culinary reputations and can vary widely depending on individual tastes.
```

#### Server (Text-only)

You can also ping the client with a text-only example. The following example 
shows how the system prompt can be used to make sure the model always knows
the current date.

```py
import requests
import json
from huggingface_hub import hf_hub_download
from datetime import datetime, timedelta

url = "http://<your-server-url>:8000/v1/chat/completions"
headers = {"Content-Type": "application/json", "Authorization": "Bearer token"}

model = "mistralai/Pixtral-Large-Instruct-2411"


def load_system_prompt(repo_id: str, filename: str) -> str:
    file_path = hf_hub_download(repo_id=repo_id, filename=filename)
    with open(file_path, "r") as file:
        system_prompt = file.read()
    today = datetime.today().strftime("%Y-%m-%d")
    yesterday = (datetime.today() - timedelta(days=1)).strftime("%Y-%m-%d")
    model_name = repo_id.split("/")[-1]
    return system_prompt.format(name=model_name, today=today, yesterday=yesterday)


SYSTEM_PROMPT = load_system_prompt(model, "SYSTEM_PROMPT.txt")

image_url = "https://huggingface.co/datasets/patrickvonplaten/random_img/resolve/main/europe.png"

messages = [
    {"role": "system", "content": SYSTEM_PROMPT},
    {
        "role": "user",
        "content": "Without browsing the web, how many days ago was Mistral founded?"
    },
]

data = {"model": model, "messages": messages}

response = requests.post(url, headers=headers, data=json.dumps(data))
print(response.json()["choices"][0]["message"]["content"])
# Mistral AI was founded in April 2023. Since the current date is November 18, 2024, we can calculate the number of days between April 2023 and November 18, 2024.

#First, calculate the days from April 2023 to the end of 2023:
#- April: 27 days (30 - 3)
#- May: 31 days
#- June: 30 days
#- July: 31 days
#- August: 31 days
#- September: 30 days
#- October: 31 days
#- November: 30 days
#- December: 31 days

#Total days from April 2023 to December 31, 2023: 27 + 31 + 30 + 31 + 31 + 30 + 31 + 30 + 31 = 272 days

#Next, calculate the days from January 1, 2024, to November 18, 2024:
#- January: 31 days
#- February: 29 days (2024 is a leap year)
#- March: 31 days
#- April: 30 days
#- May: 31 days
#- June: 30 days
#- July: 31 days
#- August: 31 days
#- September: 30 days
#- October: 31 days
#- November: 18 days

#Total days from January 1, 2024, to November 18, 2024: 31 + 29 + 31 + 30 + 31 + 30 + 31 + 31 + 30 + 31 + 18 = 323 days

#Adding the two periods together:
#272 days (from April 2023 to December 2023) + 323 days (from January 2024 to November 18, 2024) = 595 days

#Therefore, Mistral AI was founded 595 days ago from November 18, 2024.
