Fast, structured AI decisions for software automation
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.
Jev is an AI decision-making tool from TypeSafe AI that provides structured outputs for software automation, delivering rapid responses in 70-500ms. It offers probabilistic choices and scores, significantly faster and more cost-effective than traditional LLM workflows, with no output token fees.
Scored deterministically. Only candidates that fire a story trigger are sent to a model, so this one has no written angle.
Gaps in our data, not findings about the product. Their weight is redistributed across the 6 we did measure.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
Overall, the community is excited about Jev's speed and reliability, with strong interest in practical applications.
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: https://console.typesafe.ai 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](https://jevarcade.netlify.app/) interactive games that show what it can do. Typesafe's open access post: https://x.com/typesafeai/status/... Release blog with the receipts: https://typesafe.ai/blog/introdu... Tagging @diogo_almeida if you're here. Give the console a spin, try a game, and tell the team which decisions you want to automate with Jev 🚀
I've been following this team for a while and it's pretty exciting to see it taking the internet by storm. The model itself is pretty good. We're evaluating it internally and it's super impressive! So fast. For uses as a classifier it’s just…better. More reliable, way faster and cheaper. Doesn’t do chat or code They post trained LLMs to work like machines instead of please humans (“RLCD” vs RLHF) It outputs json. Categories and probabilities. Not tokens in sequence. And it outputs huge jsons nearly instantly and for free.
Hey @thisiskp_ , congrats on the launch! Excited to try it out.
The calibrated probabilities are interesting how does Jev handle decisions when the model’s confidence is low?
