A whole AI lab, small enough to read.

mini-lab trains a tiny language model, serves it behind an OpenAI-compatible API, and bills every token from prepaid credits. Every piece is open source and short enough to read in an afternoon.

Tell me a story about a dog.

Once upon a time, there was a little dog named Max. Max loved to run in the park with his red ball. One day, the ball rolled into a pond, and a kind duck pushed it back to him. Max wagged his tail and they played all afternoon.

How the lab fits together

Four stages, one Python package. Each stage feeds the next.

1 Train

A small GPT-style transformer learns short children's stories and arithmetic, on a laptop.

2 Serve

An inference server with a KV cache and continuous batching streams tokens as they are sampled.

minilab/inference
3 Meter

An OpenAI-compatible gateway checks API keys, enforces rate limits and bills every token.

minilab/api
4 Use

This platform: API keys, prepaid credits, usage, logs, a playground and a chat app.
