Jev is everywhere. But I think the real opportunity goes deeper. coding agents make constant decisions. many of them don’t need a frontier model. that adds extra model calls, token usage, and latency. so I built System1Code, a Rust-native, decision-first coding agent harness. same bug-fix task. same codebase. Rust executes. Jev chooses. your frontier model handles the hard parts. same fix. all tests passed. fewer decisions sent to the frontier model. open source ↓
