Jev — A Decision Engine for Live Software States
Jev turns a structured situation into choices and probabilities that software can use immediately.
- For
- Developers building agents and state-driven software
- Worth noticing
- The page separates action selection from text entry, with examples spanning DOM nodes, game state, card play, and SQL types.
Field notes
The page frames Jev as a structured evaluation call rather than a conversational assistant: developers define the situation, questions, and possible choices, then receive probabilities for application logic. Its examples emphasize low-latency state reading, including roughly ten DOOM decisions per second and browser automation that assigns DOM selection to Jev while reserving text entry for a smaller model. The page also catalogs projects using Jev for context compaction, DuckDB queries, simulated driving, games, and staged code review.
