Kev is a family of small decision models built on Qwen3.5 and based on the architecture described in [Jev's Architecture Unmasked](https://archerhume.com/posts/jevs-architecture-unmasked). You can use the pretrained weights or train your own. The API matches TypeSafe's [System One](https://docs.typesafe.ai/api), so you can point their Python SDK at your local server.

## Highlights

- 0.8B, 4B, and 9B models, with training code and evaluation data.
