What JEPA sees

Structured observations from the simulator: nearby agents, obstacle ranges, motion, and the goal. Camera pixels are not fed to this checkpoint.

Select an agent.

Choices

Raw JEPA scores appear after its first decision.

Environment API

The world exposes seeded reset, fixed simulation steps, observations, rewards, and per-agent termination. These are environment hooks; playing does not update model weights.
