From the Hugging Face model README
mini-chessformer-v1
A Chessformer chess engine for the browser: it reads the 64 squares, searches with MCTS, and plays one legal move.
The original Chessformer-lite release, about 7.6 million parameters.
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 hashesbrowser/entry.js— search and move picker- the ONNX net named in that manifest
Use
Point a chess-gpt-compatible runner at burrowdweller/mini-chessformer-v1. 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.
