openjev
An independent System One decision server compatible with Jev’s API, running an open DiffusionGemma model.
Where Jev makes the decision
Accepts Jev-style state and Noul, Choice, and Score questions, producing probabilities with a local model.
Why it matters
Lets existing TypeSafe SDKs connect to a self-hosted compatible service.
Claims & evidence
This is a protocol-compatible implementation, not the Jev model, an official product, or TypeSafe inference. Speed, calibration, and compatibility have not been independently retested.
About Jev
Jev is TypeSafe AI's System One decision model: it returns typed scores and choices (not free text), so agents can route, filter and gate at low latency and cost.
