Vercel: what is Jev?
Vercel's explainer frames Jev around Kahneman's System One, shows how to structure bounded decisions and separate evidence from questions, and points to the AI SDK evaluate API and the `@ai-sdk/typesafe-ai` provider.
Notes
Explainer: type safety guarantees schema conformance; example probabilities are illustrative.
