- Introducing System One Models and Jev
The article announces the release of System One Models and Jev, new AI frameworks designed to improve reasoning efficiency and reduce computational costs.
- Jev means structured output is interesting again
The author contends that Jev’s speed comes from simple single‑token structured output, suggesting the technique is easily replicable and not a major breakthrough.
Takes
made a little daycare simulator with jev where you control the chaos of the room using toys, snacks and nap-time blankets. little rascals will get FERAL. (Astra modeled all the assets in Blender first)

WTF Is Jev? 9 Things People Are Already Building With It
@mvanhorn
Here's a prompt you can (should!) throw in your codebase to surface interesting ways Jev can be integrated. --- A new AI model/tool has just been released. Deep research what its capabilities are and potential ways we could use it within this product. https://typesafe.ai https://typesafe.ai/blog/introducing-system-one-models-and-jev https://evals.typesafe.ai You should perform web searching to figure out as much as you can about Jev and what it's capable of as of Sept 2026. Don't just look at how to replace/optimize current features, but what *new* things we could do on either the customer-facing side or the backend and admin side. --- Have fun!

Breaking: Browser Use + Jev = Ultrafast ⚡ Findings flights took 7s and cost only $0.0039 🤯 > new action space every step > DOM state space > small LLM fallback to type (this video is at 1x speed btw) Built a tiny open source browser agent. try it below ↓
