Cassini is a UCI chess engine for NVIDIA GPUs. It runs a PUCT tree search guided by a 188M-parameter transformer that evaluates positions. Earlier versions were called ChessMamba and used Mamba state-space layers. Some identifiers in the code still carry that name (the ChessMamba class, MambaGM, the CM_* environment variables).  Version 6.0 was first published as Saturn 6.0 and renamed, since another engine already has that name. Current version: Cassini 6.0 (network v6, training step 1,200,000). Author: Pranav Prasanna Cassini 6.0 download from page
