Jev launches: a System One model for decisions
TypeSafe founder Diogo Almeida introduces Jev, its RLCD training method, and its focus on software decisions. The post includes a 2:56 launch video.

TypeSafe AI (Jev)'s new module turns typed questions into calibrated probabilities in ~100 ms. Using the same createChatCompletionWithJSON call with only the service and model ID changed, it delivers the same verdict 3.4x faster and 3.5x cheaper.
