Diogo Almeida, a former OpenAI researcher, has launched TypeSafe AI with a new model called Jev designed specifically for software workflows rather than conversational interaction. Unlike chatbots that generate text and require JSON parsing workarounds, Jev returns type-safe structured outputs in milliseconds with zero schema hallucination, positioning itself as a System 1 semantic reflex optimized for routing, classification, and decision-making tasks in production systems.
