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 introduces Jev, a System One model focused on making bounded decisions inside software, avoiding unnecessary text generation by LLMs.
Stop generating text when all you need is a decision! Jev is TypeSafe AI’s first “System One” model, built for a part of AI systems that we currently keep forcing generative LLMs to handle: making bounded decisions inside software. Think about what happens during an agent run.
