Profile

I ported Karpathy's microgpt [1] to TypeScript. It implements a complete GPT-2 architecture (autograd, tokenizer, multi-head attention, RMSNorm, and Adam optimizer), all in ~500 lines with zero runtime dependencies. It runs natively in the browser, no Python runtime or backend needed.You can try it in the playground: https://microgpt-ts.vercel.app/playgroundThere are preset datasets (baby names, Pokemon, company names, movie titles, etc.) or you can paste your own text. The playground shows live loss curves as the model trains, and you can step through generation one token at a time to see the probability distribution at each step.One difference from Karpathy's original is style.
