NVIDIA adds four open-weight Cosmos 3 Nano checkpoints

On November 5, 2026, NVIDIA added four open-weight checkpoints to its Cosmos 3 world model family. All four are post-trained examples of Cosmos 3 Nano with 16B trainable parameters.

NVIDIA adds four open-weight Cosmos 3 Nano checkpoints

Access and requirements

The checkpoints are downloadable, and the OpenMDW1.1 license permits commercial and non-commercial use under its terms. NVIDIA says the open weights and post-training recipes give a shared starting point for adapting the models.

Sim-Bimanual requires Linux, an NVIDIA GPU, Docker and the NVIDIA Container Toolkit. The server downloads weights and clients fetch sample inputs. The published vLLM-Omni setup was tested on one GB200, which the source says is not a minimum-memory specification. NVIDIA has not published pricing or minimum memory requirements.

What it means for creators and sellers

These checkpoints deal with simulated multi-camera, LiDAR and two-arm robot data, not with ad or social clip production. Creators who need camera-consistent synthetic footage or test data may find the multi-view Transfer-Auto output worth checking.

Closed-loop interaction requires a simulation runtime and a WSM renderer to update controls from driving inputs. The source notes that a successful short run verifies execution, not convergence, and that measuring where the models faithfully support policy learning and evaluation remains hard. Anyone testing them should check timing alignment: the source states T transitions need T+1 observations.
