TypeSafe AI (co-founded by former OpenAI engineer Diogo Almeida) has released Jev, a specialized decision-making AI model that trades flexibility for extreme speed (70-500ms response time) and cost-effectiveness ($0.0042 per million tokens—100-500× cheaper than standard LLMs). While limited to choice selection, scoring, and binary agreement tasks, Jev is positioned for guardrails, complex decision workflows, and large-scale data transformation. Currently closed beta.
