Jev - Fast, structured AI decisions for software automation

by
•
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.

Hey PH community 👋

Excited to hunt Jev today.

Jev from Typesafe is taking over the tech community like the first launches of ChatGPT, Claude Code, and the drops that made everyone stop and rebuild what they were shipping.

Jev is now open to everyone. No waitlist. Start in the console:

Jev is TypeSafe AI's System One model for typed decisions, not chat. You send unstructured state and get Choice, Score, and Noul answers with calibrated probabilities your software can act on. Parallel sampling lands those judgments in about 70 to 500ms, roughly 20 to 200x faster and 40 to 400x cheaper than comparable LLM workflows, with output tokens free.

I luckily had early access via the Netlify AI Gateway, traded some sleep this weekend, and built an arcade for Typesafe's Jev. [Not one but 7]() interactive games that show what it can do.

Release blog with the receipts:

Tagging if you're here.

Give the console a spin, try a game, and tell the team which decisions you want to automate with Jev 🚀
