Show HN: ZigFormer – An LLM implemented in pure Zig

4•habedi0•1h ago
Hi everyone,

I've made an early version of ZigFormer, a small LLM implemented in Zig with no dependencies on external ML frameworks like PyTorch or JAX. ZigFormer is modelled after a textbook LLM (like GPT-2 from OpenAI) and can be used as a Zig library as well as a standalone application to train a model and chat with it.

This was mainly an educational project. I'm sharing it here in case others find it interesting or useful.

Link to the project: https://github.com/CogitatorTech/zigformer
