Jarrod Watts points out that TypeSafe AI's Jev model, which many users don't yet have direct access to, is already available to everyone through the Vercel AI Gateway.
Jev is positioned as a "System One" evaluation model: it evaluates shared state against typed questions and returns choices, scores, and boolean probabilities, supporting classification, routing, rubric-based assessment, and automated verification, with multiple questions evaluated in parallel within a single request. Input pricing is $0.04 per 1M tokens, callable via experimentalevaluate in the ai SDK.
