Jev is TypeSafe AI's System One frontier model: unstructured state in, typed probabilistic decisions out. Instead of generating text, Jev returns Choice, Score, and Noul answers with calibrated probabilities your code can act on. Parallel sampling delivers ~70-500ms responses, about 20-200x faster and 40-400x cheaper than comparable LLM workflows, with output tokens free. Now available to everyone at console.typesafe.ai with no waitlist.

It looks amazing! Looking forward to having different town languages. I'd love to test some pt-BR texts
Nice job
The typed output approach is really interesting, especially Choice, Score, and Null being directly actionable by code.
typed decisions instead of prompt spaghetti, love it 👌 whats the latency like in practise?
The calibrated probabilities are interesting how does Jev handle decisions when the model’s confidence is low?
Congrats on the launch! The speed and cost numbers are wild
Quick question: which languages/SDKs can call Jev right now?
Is this the same team behind the previous version? I’ve been testing Jev quite a bit lately, and it’s genuinely an impressive product, fast, structured, and very practical for automation. Happy to support the launch!
