ODE-based continuous time generation + UniPC solver used, not DDPM / Score matching
Cosmos Transfer
built on top of Cosmos-Predict2.5, 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.
