# Long-WAM RoboTwin2.0-IDM

Long-WAM policy weights for RoboTwin2.0.
IDM predicts actions after generating future-video latents.

## Download

```bash
hf download Efficient-Large-Model/Long-WAM-RoboTwin2.0-IDM --local-dir ./weights/Long-WAM-RoboTwin2.0-IDM
```

## Inference

Load `model.pt` with the matching Long-WAM runtime, using `config.yaml` and
the supplied `dataset_stats.json` for preprocessing and normalization.

P48 context uses 48 past control steps plus the current observation, encoded into four clean latent frames.

Generate two future-video latents using 4 steps (imagination sigma 0.9), then predict a 32-step action chunk using 10 action steps.
Replan every 24 executed actions. Reset history at the start of each episode.

The matching inference runtime and base-model VAE/text assets are required
separately. This release contains weights and inference settings only;
optimizer states and training artifacts are not included.
