gemma4.c
An open-source educational project that implements the complete inference pipeline of the Gemma model series in approximately 700 lines of pure C. It covers core LLM inference modules including tokenization, embeddings, attention, KV cache, and quantization, with the goal of helping developers gain a transparent understanding of large language model internals.
Timeline (last 90 days)
A developer implemented the complete inference pipeline for the Gemma series of models from scratch in approximately 700 lines of pure C code.
The goal of this project is not to build a high-performance inference engine, but to construct an implementation that is small enough, transparent enough, and fully comprehensible.
The implementation covers core LLM inference components including Tokenization, Embeddings, Attention, RoPE, KV Cache, MLPs, Quantization, and Sampling.
The author wrote a validator targeting Hugging Face Transformers to check stage by stage whether the C implementation exhibits numerical deviation.
This project is positioned for understanding and education, not production deployment.
The open-source project repository is located at github.com/ryanssenn/gemma4.c.
