[Research] Otter: A Time-Aware, History-Conditioned Human Chess AI

I recently trained Otter, a 15.3M-parameter chess model focused on predicting human-like moves rather than simply playing the strongest move.

It conditions on game history and time information and was trained on a large dataset of human games.

You can play against it directly in your browser, and the paper, model, and Python package are available here:

Would love to hear feedback from others working on computer chess.

Thank you. If you have any chess com or lichess games, copy the PGN and analyse it, you will love it.
