Chess Engine - GoKawiil

Independent developer releases open-source 'Jevlike' model mimicking TypeSafe's Jev

A developer built an open-source model that mimics TypeSafe's proprietary Jev system, which scores a variable list of text options in a single pass rather than generating answers word-by-word. The project, released without official documentation from TypeSafe, includes working demos where the same attention-based scoring head selects Doom combat moves and chess moves from image inputs, along with checkpoints, code and a rendering pipeline to visualize decision traces.

Stockfish 19 chess engine released with universal binaries and new NNUE network

The Stockfish team has released version 19 of its open-source chess engine, claiming an Elo gain of up to 44 points over version 18 and a win rate more than three times its loss rate in test matches. The update introduces a new SFNNv16 neural network architecture, retires a secondary network added in version 16.1, and switches to universal binaries that auto-detect CPU features instead of requiring manual selection between AVX2, AVX-512 and similar builds. The release also adds native support for RISC-V and LoongArch processors.
