LeRobot v0.4.0 Released With Support for Large Datasets and VLA Model Integration

Hugging Face announced on October 24, 2025, that it had released LeRobot v0.4.0, an open-source framework for robot learning. The new version introduces Datasets v3.0, which supports large datasets; integration of VLA models such as Physical Intelligence’s pi0.5 and NVIDIA’s GR00T N1.5; and a plugin system for hardware integration.

For developers working with large-scale robot-learning data, Datasets v3.0’s new format for partitioned episodes and streaming support are important because they enable the framework to handle datasets larger than 400 GB. Integration of pi0.5 and GR00T N1.5 also makes it easier to evaluate and train VLA models within the same framework.
