# Model Card for 3D Diffuser Actor

<!-- Provide a quick summary of what the model is/does. -->

A robot manipulation policy that marries diffusion modeling with 3D scene representations.
3D Diffuser Actor is trained and evaluated on [RLBench](https://github.com/stepjam/RLBench) or [CALVIN](https://github.com/mees/calvin) simulation.
We release all code, checkpoints, and details involved in training these models.

## Model Details

The models released are the following:

| Benchmark | Embedding dimension | Diffusion timestep |
|------|------|------|
| [RLBench (PerAct)]() | 120 | 100 |
| [RLBench (GNFactor)]() | 120| 100 |
| [CALVIN]() | 192 | 25 |
