What is llm.c?

llm.c is a framework for training Large Language Models (LLMs) using pure C and CUDA without PyTorch or cPython.

By using llm.c, you can train LLMs about 7% faster than with PyTorch.

Since "llm" in "llm.c" is a Large Language Model and ".c" is an extension for C source files, the name of the framework like the filename of C source files is good!

As of July 2024, llm.c will focus on pretraining (especially GPT-2 and GPT-3 reproduction) and parallel PyTorch reference implementation in train_gpt2.py.

In the future, llm.c may be used in state-of-the-art ChatGPT training.

llm.c is available as open source on GitHub.

The open source license is MIT License.

Projects to Run llm.c in Other Languages and Environments

Projects to run llm.c in other languages and environments is underway.

More details can be found on the official llm.c page.

The projects as of July 2024 are as follows.

  • AMD support
  • C#
  • CUDA C++
  • Go
  • Java
  • Metal
  • Mojo
  • OpenCL
  • Rust
  • Swift
  • Zig

Summary

We introduced "llm.c," a framework for training Large Language Models (LLMs) in C language.

We hope that llm.c will lead to the widespread use of C language in generative AI!
