transfering data format between image/

Pointcloud/video etc

Roles: Sim → Real, Real → Real. Training data augmentation and generation, conditional future prediction based on actions

Cosmos Policy (fine-tuned predict)

Method and results for single-stage fine-tuning of Cosmos-Predict2 for visuomotor control + planning. Based on Cosmos-Predict2-2B-Video2World, so unlike 2.5, it does not use flow matching. imitation learning + supervised fine-tuning policy

Latent frame injection

Robot proprioception / action chunk / value are inserted as "image frame-like" latent frames into the sequence, allowing the video model's existing diffusion learning mechanism to jointly model all modalities.

Model outputs: (1) action chunk, (2) future state (image + proprioception), (3) value (expected reward of future state) generated simultaneously.
