Researchers have developed Cortex, a compact behavior-cloning policy for the game Quake, utilizing frozen visual features from a DINOv3 encoder. Trained on a subset of the Pixels2Play corpus, Cortex achieved notable progress in gameplay, reaching specific game milestones and securing kills within short episodes. Comparisons with other released models like P2P-150M and NitroGen suggest Cortex's potential, though limitations in sample size and interfaces exist. The study also explored the impact of visual token density and optimization length on performance, identifying covariate shift as a remaining challenge. AI
