# GaiaChess NNUE networks
Neural networks (NNUE) for the [GaiaChess](https://github.com/jromang/gaiachess) UCI chess engine.
**Architecture (GaiaNet)**: 12 king buckets × 768 PST + filtered threat features (~41K inputs) → 640 → CReLU + pairwise → 16 → 32 → 1, with 8 output buckets. Trained with [Bullet](https://github.com/jw1912/bullet) on self-play data.
Files are append-only: a network file, once published, is never modified — engine releases pin an exact file name.
## Networks
| File | Engine version | Notes |
|------|----------------|-------|
| `gaianet-t1-1000.bin` | never shipped | archived for reproducibility: this network generated part of the training data used by its successors |
| `gaianet-t2-1000.bin` | 4.2.0 – 4.2.5 | previous default network |
| `gaianet-t3b-1000.bin` | unreleased | +12.0 ±9.5 Elo vs t2 (SPRT, 2588 games) |
| `gaianet-t3e-1100.bin` | unreleased (default in `main`) | current default network: t3b fine-tuned for 100 more superbatches at lr/10 |
## Usage
Networks are embedded into the engine at build time:
```bash
curl -L -o nets/gaianet-t3e-1100.bin \
"https://huggingface.co/jromanghf/gaiachess-networks/resolve/main/gaianet-t3e-1100.bin"
MODEL=nets/gaianet-t3e-1100.bin RUSTFLAGS="-C target-cpu=native" \
cargo build --release --features nnue
```
Or loaded at runtime through UCI: `setoption name EvalFile value <path>`.
## License
GPL-3.0-or-later, same as the engine.
