Jev arrives on OpenRouter in beta

OpenRouter announced Jev's beta availability on September 18, 2026. It says Typesafe's model takes an app's state plus a typed question and returns a typed decision with a probability attached, rather than generating text. Reported uses include checking citations, ranking news feeds and investigating agent failures. A browser-agent creator says finding flights with Browser Use and Jev took 7 seconds and cost $0.0039. Beyond those tests, one user proposes leaving generation to a language model while Jev handles judgment calls: choosing models or tools, deciding whether to retry and flagging tasks for human review.
