Kev 1.0 pins a four-size family of Jev-style open decision models
Kev 1.0 pins checkpoints, model cards and evaluations for 0.8B, 4B, 9B and 27B decision models compatible with TypeSafe's System One API.
What happened
Event details
Released on October 1, Kev 1.0 versions the existing 0.8B, 4B, 9B and 27B checkpoints, cards, evaluation suites and serving code. No models were newly trained for this versioned release. The self-hostable project continues its Jev-inspired direction with a TypeSafe-compatible interface. Its release documents evaluation scope and limitations; the results do not establish universal superiority over Jev.
Assessment
Why it matters
Provides a reproducible, multi-size open-source baseline and deployment alternatives for Jev-style decisions.
