Jevman compares decision models across 100 Pac-Man games each

opper.ai Editor score 6/10

The benchmark has jev, kev, clef, and several GPT models play 100 games each, with results on a leaderboard and code available to run other models. It offers a reproducible game-based comparison, though its value for broader agent evaluation is unclear.

What
Jevman benchmarks AI decision models playing Pac-Man against the classic scripted ghosts.
How
The game sends maze state as JSON to a model endpoint, which returns direction probabilities; late answers use a backup rule.
Why it matters
Recorded, replayable games and CI score checks give engineers a way to inspect and verify model evaluations.
