### AI overview

The article introduces Jev, a transformer-based AI model from TypeSafe AI that produces calibrated decisions rather than text. It is designed to help AI agents choose tools and retries, with low cost and fast responses, and has been integrated by platforms including Vercel, Cloudflare, LangChain, and Langfuse.

### Source excerpt

Early signs suggest Jev is gaining traction among developers, with a surge in demand last week causing TypeSafe AI to briefly lose the ability to serve users from its API.
