At a glance
Jev is a developer model that TypeSafe AI released in September 2026. It is not a model that writes text like ChatGPT, and when you give it an input (text, JSON, etc.) and a question, it returns only structured decisions such as a yes/no probability, one of the choices, or a score. It suits automation that repeats short decisions in large volumes, such as classifying customer inquiries, detecting fraudulent transactions, content review, and choosing the next action of an AI agent.
