What is llama2.c?

llama2.c is a C library that can infer LLaMA 2.

llama2.c is developed under the influence of llama.cpp.

If you are interested in llama.cpp, please click the following.

llama2.c is available as open source on GitHub.

The open source license is MIT License.

The features and limitations of llama2.c are as follows

  • The ability to train the LLaMA 2 LLM architecture in PyTorch and infer LLaMA 2 with a file "run.c" of about 700 lines written in pure C
  • Super-simple, minimal and educational compared to llama.cpp
  • (As of August 2024) only fp32 models can be inferred, so it is not possible to load models larger than 7B or to quantize the modelssp

Projects that Run llama2.c in Other Languages and Environments

Projects are underway to run llama2.c in other languages and environments.

Details are given on the official llama2.c page.

The main projects are as follows.

  • C language
    • llama3.c (@jameswdelancey): Ported version of llama2.c with LLaMA 3 8B base and instructions
  • C++ language

Introductory Videos of llama2.c

These are introductory videos of llama2.c.

Summary

We introduced llama2.c, a library for inferring LLaMA 2 in C language.

We hope that more people will be influenced by llama2.c to learn C language!
