| # Hyperion-Chess | |
| Chess engine for [AI Chessathon 2026](https://aichessathon.com). | |
| ## Overview | |
| Hyperion-Chess is a competition-grade Python chess agent combining: | |
| - **Iterative deepening alpha-beta** with quiescence search | |
| - **Numba-jitted PST evaluation** (Phase 1) | |
| - **Micro-NNUE** int8 weights (Phase 3, trained locally on SF-labelled FENs) | |
| - **4-man Syzygy tablebases** for perfect endgames within the 50 MB zip cap | |
| - **Dynamic time management** for 120s + 0.5s control | |
| ## Source code | |
| GitHub: [shahaman098/hyperion-chess](https://github.com/shahaman098/hyperion-chess) | |
| ## Weights (coming soon) | |
| | File | Description | | |
| |---|---| | |
| | `nnue.npz` | Quantized Micro-NNUE (768→128×2→32→1) | | |
| | Syzygy 4-man | Endgame tablebase (too large for HF; shipped in competition zip) | | |
| ## Usage | |
| This is a **competition submission**, not a pip package. The platform imports `agent.get_move(fen, time_left_ms)`. | |
| ```python | |
| import agent | |
| move = agent.get_move("rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1", 120_000) | |
| # → "e2e4" | |
| ``` | |
| ## Training | |
| Training scripts live in the GitHub repo under `training/`. Positions may be labelled with Stockfish at train time (allowed by competition rules); only self-trained weights ship in the zip. | |
