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's first System One model, Jev, is now available on the B.AI API. Designed for high-speed structured decision-making inside software, Jev does not generate text.
