Chinese students found 2,170 real world uses for Jev, and it’s already replacing thousands of unnecessary LLM decisions
1 → 1,865 new repos appeared after launch and 305 existing projects added Jev. The new repos picked up 43,750 stars in one week
2 → 77% of projects use Jev for attribute judgment, 52% for scoring and ranking, 31% for action selection, and some for routing, filtering and model selection
3 → 36.8% use all three interfaces (Choice, Noul and Score), so one system can hand Jev several kinds of decisions
4 → The paper walks through real workflows: browser automation, code review triage, trimming tool history, model routing, risk gates on tool calls, and a controller for a Mario emulator
5 → Most of these are tiny calls: pick a tool, check an action, route a request, decide what context to keep. Jev handles them without another expensive LLM call
Jev is starting to look like a cheap decision primitive for AI agents
