What Is Jev 1.14?
Jev 1.14 is the second public version of Jev, the System One decision model from TypeSafe AI. Like Jev 1.13, it does not generate text: it returns typed answers, a yes/no with a probability, a choice from a defined set, or a score, with calibrated probabilities for routing, classification and other decision points in an application. It was released on 14 October 2026 and is available on AI/ML API as typesafe/jev-1.14.
What Changed From Jev 1.13
- Quality: TypeSafe describes 1.14 as better across the board, with the largest gains in languages other than English.
- Images: image input, experimental in 1.13, is extended in 1.14 and remains marked experimental.
- Box questions: a new question type,
box, asks where something is in an image.
Pinned Version vs the typesafe/jev Alias
typesafe/jev-1.14 always runs version 1.14. The alias typesafe/jev points to the newest Jev release and resolves to 1.14 today, but will move when TypeSafe ships the next version. Use the pinned id when probabilities feed fixed thresholds. Jev 1.14 is also the decision model behind the Jev Router on AI/ML API.

Use cases

Classification and moderation in multilingual products, where TypeSafe reports the largest improvement over 1.13.
Decisions about images: yes/no or choice questions about what an image shows, and Box questions that locate an object in the image.
Scoring content or requests on a defined scale and acting on the score in code, without parsing generated text.
