Jev: The ChatGPT Co-Creator's System One Model Can't Talk

Diogo Almeida, who co-invented RLHF and InstructGPT at OpenAI, spent two years building Jev: a System One model that cannot generate text, only typed decisions with calibrated confidence. TypeSafe AI prices input at $0.042/MTok, output free, running 70-500ms. Automation needs a model it can trust, not one that talks.
