Before you dive in
What you’ll find in the original
- Install the TypeSafe extra, set TYPESAFE_API_KEY, and use typesafe:jev-latest or a versioned model identifier.
- Express each decision as a typed field; Pydantic AI turns field descriptions, enums, and boolean criteria into parallel Jev questions.
- Pin the model after tuning thresholds, respect option/context limits, and fall back for generation, arithmetic, adversarial text, or uncertain routes.
Worth knowing
The page explicitly warns that Jev can confidently answer badly; teams should measure accuracy and hand-off rates on their own labelled data.
