100-word summary
Hugging Face and Nvidia just published a guide showing how to teach Cosmos Predict 2.5 to generate robot training videos using only 92 examples. The trick is LoRA adapters, which freeze the base model and train tiny add-on layers instead. That lets robotics labs customize the video model on a single 80GB GPU rather than renting a server farm. One team trained theirs in 2.5 hours, then generated synthetic robot arm footage by feeding it a starting frame and a text prompt. The catch: you still need serious hardware, and results vary with dataset size. But suddenly, creating fake training data for physical robots doesn't require Pixar-level resources.
