Jev lands on Vercel AI Gateway and OpenRouter
On 16 September 2026, Vercel shipped TypeSafe AI’s Jev on AI Gateway. Changelog model id: typesafe-ai/jev. AI SDK 7 exposes it through experimental_evaluate — Choice, Score, and Boolean over a shared state, with typed answers and probabilities (no text parse step).
OpenRouter lists the live model as typesafe/jev-1.13 — $0.042 / $0 per 1M tokens (input / output), 32K context (page checked 19 Sep 2026). That same week OpenRouter and TypeSafe also posted explainers / handshake notes.
A Vercel post claimed ~13% of AI Gateway teams used Jev on day one (2× the GPT-5.6 family, 6× Fable 5.1). That adoption figure is unverified beyond the tweet — not independently verified by ModelSystem.One.
Workflow multiples in the changelog (up to 193.6× faster / 444.6× cheaper vs LLMs) remain TypeSafe vendor claims.
