How to get access to Jev

This site issues a jv_live_ key against a live account instantly, so you can call the model within minutes of signing up — self-serve, no setup.

There are two ways to get Jev access. The official route is to sign in at typesafe.ai and use your own keys. The faster route is to sign up here, buy a small credit pack, and receive a jv_live_ key that works against the same hosted System One model immediately — plus ready-made workflow endpoints on the same key.

Signing up and getting a key

• Sign up and open the dashboard
• Buy a credit pack — small is fine to start, credit does not expire
• Copy your jv_live_ key from the dashboard
• Send your first decision to the API and you are live

Your first call after sign up

Once you have Jev access, a decision is one request: POST https://jevtypesafeai.com/api/v1/decide with your jv_live_ key in the header, a model, the state you want judged, and a map of questions. You get back a typed answer with calibrated probabilities in roughly 70–500ms. The same key works from the playground, from code, and through the MCP server.

Do you need to sign up to try it?

No — you can run live decisions in the browser playground before you sign up, to confirm Jev fits your case. Sign up when you want a jv_live_ key of your own for code. Either way access is instant and self-serve, and it costs only usage — about $0.001 per decision, billed by input tokens ($0.42 per million, output free).

Is there still a Jev waitlist?

Jev initially launched in limited, waitlist-gated early access. That is no longer a barrier: direct access to Jev is now open and self-serve, so there is no Jev waitlist to join. You can create an official key at console.typesafe.ai, or get an instant hosted jv_live_ key here and start calling the model right away.
