Get started

Jev from TypeSafe AI is now available on AI Gateway .

Jev is a probabilistic decision model for software: state goes in, typed Choice, Score, and Boolean answers come out.

Regular language models generate text one token at a time, which the application then parses and validates. Jev evaluates all declared questions in parallel and returns typed answers plus probabilities directly. That removes unnecessary text generation and makes it straightforward to automate clear cases while routing uncertain ones to review.

TypeSafe reports Jev was up to 193.6x faster and 444.6x cheaper than LLMs on its workflow evaluations.…
