Cosmos3 Nano Sim Bimanual generates video in response to arm movements and gripper controls. Start with an image of the supported robot and scene, describe the task, and steer its arms while watching the generated observations. Use it to build an interactive manipulation playground: reach across a table, open or close a gripper, and reset the scene to explore another movement.

Supported embodiments

The hosted checkpoint supports AgiBot. Other robot embodiments are not supported by supplying a different starting image or substituting their actions. Choose the embodiment guide for input conventions and integration details. The model predicts visual evolution rather than exposing a physics engine’s state or task-success scores. Its held-controller interface is suited to interactive exploration; custom-policy evaluation requires a compatible action mapping and validation of the generated dynamics. For runnable Python code, see the AgiBot simulation examples in the Reactor Cookbook. Already have a physics simulator? Use Cosmos3 Nano Sim Transfer to render that simulator’s depth observations instead.
