TypeSafe AI launches Jev, a decision-focused AI 193x faster and 444x cheaper than ChatGPT

Jev’s architecture, called System One Models, avoids text generation entirely, outputting structured decisions (e.g., ‘Yes/No’ with probability) instead of human-readable responses. This design eliminates latency from text generation and reduces costs by bypassing reinforcement learning from human feedback (RLHF), which TypeSafe AI says introduces inconsistencies. Early use cases include real-time email sorting, CAPTCHA solving, and automated moderation. However, a demo of Jev handling 2,015 foreign exchange trades in 125 seconds (an average of 220 milliseconds per trade) resulted in a –3.8% loss, highlighting that speed alone doesn’t guarantee profitability. The company emphasizes Jev’s role in shifting AI from conversational tools to automated decision-making systems.
