Jev: AI Decision Engine

Project photo 1

Jev is an AI system that makes typed decisions and probabilities based on state, contrasting with traditional AI models that generate text.

Pattern Jev AI decision models

Most AI models generate text Jev by @typesafeai takes a different approach: State → typed decisions + probabilities No paragraphs. No JSON parsing. No retrying because the model returned the wrong format And the numbers are interesting: → 193.6× faster → 444.6× cheaper → $42 / billion input tokens → ~70–500ms response time TypeSafe reports these results across its System One workflow evaluations The interesting part isn't replacing GPT/Claude It's using Jev for the millions of tiny decisions inside an AI system: • Should I retry? • Which tool should I call? • Should I escalate? • Is this risky? • Which route should I take? Then let the expensive LLM handle the actual generation LLMs generate. Jev decides That's a pretty interesting architecture for AI agents
