Long-WAM RoboCasa-GR1 2.4s

Long-WAM policy weights for RoboCasa GR1 with 2.4 seconds of observation history. The duration denotes the history window, not the model parameter count or action chunk.

History and inference

P48 uses 48 past control steps plus the current observation: 2.4 seconds at 20 Hz. Sample history every four control steps; 13 RGB frames encode into 4 clean latent frames.

Load model.pt with the matching Long-WAM RoboCasa GR1 runtime and config.yaml. Use the supplied dataset_stats.json for the GR1 action normalization and state/action adapter. Input is the single ego_view RGB camera (256×256, preprocessed to 224×224), with 58-D model proprioception and 29-D actions.

Generate two future-video latents using 4 video denoising steps (sigma 0.9), then predict a 16-step action chunk using 10 action denoising steps. Execute 16 actions before replanning. Record observations at every 20-Hz control step; repeat the earliest available frame when history is short, and reset history at each episode boundary.

The matching runtime, GR1 simulator/assets, Wan VAE and task text embeddings are required separately. This release contains weights and inference settings only, without optimizer states or training artifacts.
