Jevosaurus

Meet Jevosaurus, a dino run by a small decision model. It plays the Chrome dino game. Each time an obstacle comes near, the game is described in a few lines of text and the model answers one question: jump, duck or keep running? Everything runs in this tab on WebGPU.

Jevosaurus Index

Every model plays the same three seeded courses with the word prompt, up to 60 seconds each. Real time: the game keeps running while the model thinks, so speed matters. Turn-based: every answer lands instantly, so only judgment counts. Scores are averaged over the courses.
