TypeSafe AI Launches Jev, a Decision-Only Model That Cuts AI Agent Costs by 444x

TypeSafe AI has unveiled Jev, a System One model designed to separate expensive reasoning from fast, structured decisions—running up to 193 times faster and 444 times cheaper than frontier LLMs on classification tasks. The model represents a fundamental shift in how AI agents and decision loops are architected, moving cost-heavy inference out of every decision branch and routing requests through a lightweight, type-safe classifier instead.
