LLaMA.NET

.NET library to run LLaMA using ggerganov/llama.cpp.

Build 🧰

To build the library, you need to have CMake and Python installed. Then, run the following commands at the root of the repository.

# Pull the submodules
git submodule update --init --recursive

# Build and prepare the C++ library
python scripts/build_llama_cpp.py

Then, build the .NET library using dotnet:

# Build the .NET library
dotnet build LLaMA.NET/LLaMA.NET.csproj

The built library should be located at LLaMA.NET/bin/Debug/netXXXX/LLaMA.NET.dll.

Currently only Linux is supported. Work is being done to dynamically load the C++ library on other platforms.

Usage 📖

Model Preparation

To use the library, you need to have a model. It needs to be converted to a binary format that can be loaded by the library. See llama.cpp/README.md for more information on how to convert a model.

The model directory should contain the following files:

• ggml-model-q4_0.bin: The model file.
• params.json: The model parameters.
• tokenizer.model: The tokenizer model.

Inference

To run inference, you need to load a model and create a runner. The runner can then be used to run inference on a prompt.

using LLaMA.NET;

LLaMAModel model = LLaMAModel.FromPath("/path/to/your/ggml-model-q4_0.bin");
LLaMARunner runner = model.CreateRunner()
    .WithThreads(8);

var res = runner.WithPrompt(" This is the story of a man named ")
    .Infer(out _, nTokensToPredict = 50);
Console.Write(res);

model.Dispose();
