GuppyLM

GuppyLM is a tiny language model that pretends to be a fish named Guppy. It speaks in short, lowercase sentences about water, food, light, and tank life. It doesn't understand human abstractions like money, phones, or politics — and it's not trying to.

It's trained from scratch on 60K synthetic conversations across 60 topics, runs on a single GPU in ~5 minutes, and produces a model small enough to run in a browser.
