FastOPD

Researchers have proposed FastOPD, a new framework that compresses large foundation vision-language-action models into lightweight versions suitable for real-world robot deployment. The approach uses efficient on-policy distillation, allowing small models to learn directly from a big model's behavior. The work was released as a paper on arXiv in the robotics category, and early discussion is focused on whether it makes advanced robot policies cheaper and easier to run on hardware.
