What is GGML?
GGML is a tensor library for machine learning to enable large models and high performance on commodity hardware. Development of ggml is underway for a more efficient format and new k-quant method, so it is not stable. Read more at GGUF documentation.
Model Weights Offered
| Model | Size(GB) | Description | Performance |
|---|---|---|---|
| jindo-7b-instruct | 12.6 | original model weight | |
| jindo-7b-instruct.ggmlv3.f16.bin | 12.5 | model weight converted to ggml f16 format | |
| jindo-7b-instruct.ggmlv3.q4_0.bin | 3.73 | 4-bit quantization in super-blocks containing 8 blocks, each block having 32 weights. Scales and mins are quantized with 6 bits. | Legacy |

Inference
To perform inference using the danielpark/ko-llama-2-jindo-7b-instruct-ggml weights fine-tuned with llama2 on CPU or GPU,
you need to set up the appropriate installation and configuration on your system. Please refer to the llama.cpp repository,
the langchain's documentation, and follow the guides for various dependency software as needed. 
Using LLaMA CPP module in Lang-Chain
$ pip install langchain ctransformers llama-cpp-python
from langchain.llms import LlamaCpp
from langchain import PromptTemplate, LLMChain
from langchain.callbacks.manager import CallbackManager
from langchain.callbacks.streaming_stdout import StreamingStdOutCallbackHandler
CPU
# Make sure the model path is correct for your system!
llm = LlamaCpp(
model_path="./models/jindo-7b-instruct-ggml-model-f16.bin",
input={"temperature": 0.75, "max_length": 2000, "top_p": 1},
callback_manager=callback_manager,
verbose=True,
)
GPU
If the installation with BLAS backend was correct, you will see an BLAS = 1 indicator in model properties.
Two of the most important parameters for use with GPU are:
- n_gpu_layers - determines how many layers of the model are offloaded to your GPU.
- n_batch - how many tokens are processed in parallel.
n_gpu_layers = 40 # Change this value based on your model and your GPU VRAM pool.
n_batch = 512 # Should be between 1 and n_ctx, consider the amount of VRAM in your GPU.
# Make sure the model path is correct for your system!
llm = LlamaCpp(
model_path="./models/jindo-7b-instruct-ggml-model-f16.bin",
n_gpu_layers=n_gpu_layers,
n_batch=n_batch,
callback_manager=callback_manager,
verbose=True,
)
Metal
n_gpu_layers = 1 # Metal set to 1 is enough.
n_batch = 512 # Should be between 1 and n_ctx, consider the amount of RAM of your Apple Silicon Chip.
# Make sure the model path is correct for your system!
llm = LlamaCpp(
model_path="./models/jindo-7b-instruct-ggml-model-f16.bin",
n_gpu_layers=n_gpu_layers,
n_batch=n_batch,
f16_kv=True, # MUST set to True, otherwise you will run into problem after a couple of calls
callback_manager=callback_manager,
verbose=True,
)
Using C Transformers module in Lang-Chain
from langchain.llms import CTransformers
llm = CTransformers(model="./models/jindo-7b-instruct-ggml-model-f16.bin", model_type='llama')
print(llm('LLM Jindo is going to'))
Web Demo
I implement the web demo using several popular tools that allow us to rapidly create web UIs.
| model | web ui | quantinized |
|---|---|---|
| danielpark/ko-llama-2-jindo-7b-instruct. | using gradio on colab | - |
| danielpark/ko-llama-2-jindo-7b-instruct-4bit-128g-gptq | using text-generation-webui on colab | gptq |
| danielpark/ko-llama-2-jindo-7b-instruct-ggml | koboldcpp-v1.38 | ggml |

CLI Inference using Quntinized Weight
To use the program with the desired settings, execute the following command:
./main -t <number_of_cpu_cores> -ngl <number_of_layers_to_offload> -m ko-llama-2-jindo-7b-instruct-ggml.bin --color -c 2048 --temp 0.7 --repeat_penalty 1.1 -n -1 -p "### Instruction: Write a story about llamas\n### Response:"
Please make the following changes:
- Replace
<number_of_cpu_cores>with the number of physical CPU cores you have. For example, if your system has 8 cores/16 threads, use-t 8. - Replace
<number_of_layers_to_offload>with the number of layers to offload to the GPU. If you don't have GPU acceleration, you can remove the-nglargument. - If you want to have a chat-style conversation, replace the
-p "<PROMPT>"argument with-i -ins.
