DreamDojo 2B · GR-1
DreamDojo 2B · GR-1 is a 2-billion-parameter action-conditioned video world model designed for humanoid robotics simulation, visual model-predictive control, and large-scale rollout data augmentation.
Example usage
DreamDojo 2B · GR-1 runs on the Dream Engine inference stack and is accessible via the typed Python SDK. Generate an API key, set it as DREAM_API_KEY in your shell, and you’re ready to roll out.
