maia-1100 (Lc0 fine-tune)

config.yaml: The config file was originally downloaded from: https://github.com/CSSLab/maia-chess/blob/master/move_prediction/replication-configs/final/1100_final.yaml
The model was originally downloaded from: https://github.com/CSSLab/maia-chess/releases/download/v1.0/maia-1100.pb.gz

Use with ChessNets

python

from chessnets.pipelines.lc0 import Lc0Pipeline

pipeline = Lc0Pipeline.from_pretrained("shermansiu/maia-1100")
predictions = pipeline("1. e4 e5")

Checkpoint artifacts

config.json: canonical, fully materialized ChessNets architecture config
model.safetensors: decoded float32 PyTorch tensors
provenance.json: source and conversion hashes
original/model.pb.gz: original Lc0 protobuf checkpoint
training/original_lczero_training_config.yaml: original training config

The learned protobuf weight layers used LINEAR16 encoding. Conversion decoded those values into float32 tensors; it cannot restore precision already lost in the source encoding.

Intended use and limitations

This Maia-1 network is intended to imitate moves from its target human rating group. It is a move-prediction model, not a calibrated estimate of an individual player's strength.

Review legal moves and probabilities in context. Outputs are not guarantees of playing strength, fairness, or suitability for high-stakes decisions.
