π0.5: A General-Purpose AI Model Enabling Robots to Clean New Homes

Physical Intelligence has developed π0.5, a robotic foundation model capable of generalizing complex cleaning tasks, such as tidying a kitchen or bedroom, to entirely new environments. Unlike previous robots limited to controlled settings, π0.5 leverages co-training on diverse heterogeneous data, including multimodal data and data from various robots, to learn diverse skills and understand their semantic context. Experiments show π0.5 can perform multiple tasks in unseen homes, exhibiting human-like flexibility and resourcefulness despite occasional failures. This represents a significant step toward truly generalizable physical intelligence.
