5 projects put Jev to work as the decision engine inside agents

The author surveys real projects built with Jev and argues the bigger story isn't Jev itself but its role inside agents as a lightweight decision layer:
- browser-use/jev-ultrafast (16.6k stars): Jev picks the next browser action without an expensive LLM call — booked Zürich → London on Google Flights in 7.1s including text generation.
- tamaratran/fast-jev-compaction (6.5k stars): uses Jev to decide which context stays and what gets dropped.
- TheoLeeCJ/SemIf (4k stars): open-source local implementation of Jev-style decision making.
- jarrodwatts/jev-trader (2.1k stars): real-time trading loop choosing between buy, sell, or wait.
- kerpopule/hermes-jev-skills (670 stars): Jev for routing, memory, compaction, and skill selection.
Key takeaway: swapping some LLM calls for a small decision component can slash agent cost and latency.
