MolmoAct-2 lineage hub — bimanual manipulation base family from Ai2. Not directly deployable; pick a fine-tune below.



MolmoAct-2 is Ai2's vision-language-action model trained on diverse bimanual manipulation data. The MolmoAct-2 base is **not directly deployable** — Ai2 designed it as a lineage anchor from which per-embodiment fine-tunes are derived. Each fine-tune carries its own contract (state shape, camera layout, action horizon) suited to its hardware. \[source: [https://huggingface.co/allenai/MolmoAct2](https://huggingface.co/allenai/MolmoAct2)]

Pass the fine-tune's tag to `Robot(model=...)`. Passing `"molmoact2"` (the base tag) raises `BaseNotDeployableError` with the list of available fine-tunes.

```python
import newt

# This raises BaseNotDeployableError — use a fine-tune tag instead.
# robot = newt.Robot(model="molmoact2")

# Use the SO-101 fine-tune:
robot = newt.Robot(model="so101", ...)
```
