About JevAbout Jev

Official & Getting Started

Primary sources from TypeSafe: the launch announcement, documentation, quickstart, and console.

Start here when a Jev detail affects code or architecture. These links lead to TypeSafe's own launch material, documentation, quickstart, and console, so they are the best place to confirm the current request contract, model names, access status, and terminology. Read the System One overview before treating Jev like a chat model: the application supplies state and typed questions, while ordinary code owns thresholds and side effects. Because Jev is new, provider behavior can change faster than third-party tutorials. Recheck the official source immediately before implementing a production workflow.
