Jev: AI Decision Engine

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
