Real-time Doom demo powered by Jev
A game demo shows real-time decisions. Diogo says it makes about ten Jev calls per second; the post includes a 2:43 video.

Every 0.2 s Jev answers three questions (move? jump? fire?), with real odds shown in the sidebar; under one on-screen anti-dithering rule, 7 of 10 runs reach the end but none win yet.
Claude Opus 5 built a platformer. Jev plays it. Every 0.2 s Jev answers 3 questions (move? jump? fire?); the sidebar shows its real odds. With one on-screen rule against dithering, 7 of 10 runs reach the end. None win yet.
