π0.5 cleans kitchens and bedrooms in homes not seen during training

Physical Intelligence/π model family

π0.5, a vision-language-action model from Physical Intelligence, generalizes to new home environments after training on ~100 homes. A mobile manipulator running it cleaned kitchens and bedrooms in entirely new homes, performing multi-stage 10–15 minute tasks.

• π0.5 trained on ~100 homes, successfully generalizes to unseen 101st home without additional fine-tuning.
• Demonstrated tasks include cleaning kitchens, tidying bedrooms, and multi-stage chores lasting 10–15 minutes.
• Co-trained on diverse data: robot demos from multiple platforms, web data, and language labels for open-world generalization.
• Represents progress on embodied AI's hardest challenge: robust operation in new physical environments.
