Jev-Style
<!-- mcp-name: io.github.lawrence3699/jev-style -->
Small, calibrated decision models you run on your own machine, plus the tooling to put them to work in AI agents.
New in 0.3.0: Jev-Style-2B-Decision-v3. It scores 73.6 % on the 231 public items of JevBench v1.4.1 (self-run with the official harness on the GGUF F16 build, not an official board entry), 9.5 points above the 0.8B and the highest among the Qwen3.5-2B-family systems on the board. Its lead over decider-2b (71.0 %) is inside the 95 % confidence interval, 42 of the 82 board systems score higher, and hosted Jev is well ahead at 86.6 %. Try it in your browser, or run it locally with jev-style serve --release 2b. The default release is still the 0.8B, so existing setups get the same model as before.
Jev-Style is a family of small decision models built on Qwen3.5. The current releases are Jev-Style-2B-Decision-v3 (1.27 GB at 4-bit) and Jev-Style-0.8B-Decision-v3 (0.53 GB at 4-bit, the default); both, with every build and demo, are in the v3 collection. You give a model text or JSON and some typed questions, and it returns a calibrated probability for every option in one forward pass. The server's API follows the public systemone request shape, so clients written for Jev-compatible servers can call your laptop instead.
This repository is the part that makes the model useful day to day:
Shortened. The full README is on GitHub.
