SQL, meet a little common sense.

Ask your tables for “customers about to cancel.” Filter and rank rows by what they actually mean.

A DIFFERENT KIND OF AI

The next move.
Without the monologue.

A Jev AI agent puts quick decisions to work. Jev picks, scores, and sorts. Code takes action. Other models step in when the job needs planning or words.

A few things
worth knowing.

The useful bits, minus the jargon.

What is a Jev AI agent?

An agent that uses TypeSafe’s Jev model to make decisions during a task: choosing an action, evaluating an item, or routing work. Tools execute the actions; another language model can handle planning and writing.

Can I run these agents here?

Right now, you can explore the community demos and visit their original projects. Try takes you to JevFlow’s early-access page for the experience you picked. Hosted agents are not available here yet.

Does Jev write text or see screenshots?

Jev returns structured choices, scores, and truth probabilities from text-based state. In these projects, surrounding tools handle browser observations, game state, and execution. Other models can handle text generation.

Are these official Jev projects?

JevFlow is independent. These projects were built by community developers, with author and source links on every card. Jev itself is made by TypeSafe.

Is every decision correct?

No. A structured answer can still be wrong. Good agent workflows validate actions, check outcomes, and send uncertain cases for review. A compelling demo is not a reliability guarantee.

Where can I find the API and pricing?

For current model access, documentation, and pricing, visit TypeSafe’s official website. Running a full agent may also involve browser, hosting, and other model costs. Visit TypeSafe ↗
