minichess-gpt

A small neural chess engine that runs in the browser. It looks at the current board, searches ahead, and plays one legal move.

Full-precision weights. Prefer this when the browser can use a GPU.

What's in this repo

This is a browser chess engine package (chess-gpt-package-v1), not a Transformers checkpoint.

A compatible runner loads:

browser/manifest.json — file list and hashes
browser/entry.js — search and move picker
the ONNX net named in that manifest

Use

Point a chess-gpt-compatible runner at burrowdweller/minichess-gpt-final-fp32. It calls loadPackage → newGame → chooseMove({ history, legalMoves }) and must return one of those legal moves.

The net is small on purpose. Strength comes from searching at move time.
