How builders describe it
Apache-licensed, locally runnable Jev-style decision models (0.8B, 4B, 9B on Qwen3.5) with released weights, training code, a System One-compatible server, frozen eval suites, and a playground.
Jared Palmer shipped Kev-0.5B: a tiny open-source Jev-like decision model with a TypeSafe-compatible API, based on Qwen2.5-0.5B, that you can train and run on a MacBook Pro. Model card and weights are on GitHub. — @jaredpalmer (643 likes)
The decision Jev makes
Benchmark questions with known answers, to check accuracy and confidence.
Where it fits
Head-to-head tests, calibration studies and independent research into how well Jev decides, how fast, and at what cost. All 682 benchmarks & research projects →
