TypeSafe AI's Jev lands on AI Gateway: decisions without token-by-token text, up to 193.6x faster in vendor tests
TypeSafe AI's probabilistic decision model Jev is now available on Vercel AI Gateway, letting an application hand in a state and get back typed Choice, Score and Boolean answers with probabilities. Regular language models generate text one token at a time for the application to parse and validate; Jev evaluates all declared questions in parallel and returns structured answers directly. TypeSafe reports Jev was up to 193.6x faster and 444.6x cheaper than LLMs on its workflow evaluations, for uses such as picking the next tool in an agent loop, deciding whether to continue or stop, scoring risk, and verifying outputs.
