AI Models

Former OpenAI researchers launched Jev, a model that decides

It chooses instead of writing text. It costs $0.042 per million tokens.

TypeSafe AI launched Jev on September 15 with $40 million in seed funding led by DCVC. The model returns choices and probabilities instead of text. It charges $0.042 per million input tokens, and output is free.

Jev returns a choice and a probability in under a second

How the model works inside is still a secret.

Jev reads a piece of text and answers questions whose possible answers the developer defines. It can pick an option, rate something on a scale, or give the chance that a statement is true. TypeSafe has not published the model’s design or size.

Agents & Apps

Developers use Jev as a fast judge inside their apps

It is far cheaper than big models, but not always as accurate.

Early testers use Jev to route requests, check risky agent actions, and grade other models’ work. Vercel reports faster and more accurate safety checks. In one email test, Google’s Gemini was slightly more accurate but 10 to 20 times more expensive.
