New: every message picks a fast or a slow model

Jev

Jev is TypeSafe AI's System One API for discovering available models and evaluating structured state with Noul, Choice, and Score questions.

What agents can do

Actions2

  • Evaluate state

    Evaluate one shared state against one or more named Noul, Choice, or Score questions in parallel; each call performs usage-priced inference.

  • List models

    List the Jev model names and aliases available to the connected account for use in evaluations.

How it connects

You paste an API key from Jev on a page Composio hosts, so the key never passes through Definable.

Keep the connection to yourself or share it with your workspace. Any action that writes or sends can wait for your approval.
