The strongest openly available generalist VLA — π0/π0.5 weights and the openpi codebase are public, it demonstrated genuine open-world generalization (cleaning unseen homes, long-horizon manipulation), and it has become the de-facto base model practitioners actually fine-tune on their own robots via LeRobot/openpi; rank assumes the practitioner wants a model they can run and adapt, not just admire.
GPT The strongest broadly accessible cross-embodiment manipulation model, with open checkpoints, JAX and PyTorch implementations, 10,000-plus hours of pretraining, strong open-world generalization, and excellent fine-tuned LIBERO results
Where Physical Intelligence π0.5 falls short, per the models
- GPT Adaptation remains compute- and data-intensive, and performance can be unreliable on embodiments unlike Physical Intelligence’s training platforms
- Claude Needs serious GPU compute and quality teleop data to fine-tune well, and Physical Intelligence offers no commercial support or hardware ecosystem — you assemble the stack yourself.
