Ars Technica interviews MIT's Vincent Sitzmann, Runway CTO Anastasis Germanidis, and World Labs co-founder Ben Mildenhall to explain the definition of world models, the diverging technical approaches, and the questions that remain unsettled.
Hugging Face LeRobot has released v0.6.0: pip install lerobot no longer includes dataset and training dependencies by default, requiring extras to be added as needed; GR00T N1.5 has been replaced by N1.7; and the minimum PyTorch version has been raised to 2.7.
Why it matters: The release notes list specific breaking changes and migration methods, so developers in the middle of upgrading can use them to check their installation, configuration, and training workflows.
Reachy Mini, a collaboration between Pollen Robotics and Hugging Face, features the Conversation App, enabling fluent conversation, to-do list management, task reminders, and discussions about music. The robot has long-term memory across sessions and vision capabilities, allowing it to recognize what users show it. It is aimed at home AI companionship, and purchases can be made at reachy-mini.ai.
Hugging Face has released the LeRobot Humanoid full-stack project, with a pair of humanoid robot legs priced at $2,500, built from 3D-printed parts and off-the-shelf components. The release includes a bill of materials, 3D printing files, wiring documentation, assembly instructions, and software tools for calibrating and controlling the robot both on the physical body and in simulation.
Why it matters: The original text explains the hardware cost, the open materials, and the simulation-to-real design loop, which can be used to assess the impact of a low-cost humanoid platform on research workflows.
Hugging Face has released LeRobot v0.5.1, which includes multiple fixes and feature updates. Key changes include a modular refactor that splits LeRobotDataset into DatasetReader and DatasetWriter.
Hugging Face LeRobot releases v0.4.4, adding support for OpenArm, OpenArm Mini, and G1 teleoperation, as well as damiao and RobStride CAN motor drivers, and expanding the camera API with CLI support for configuring camera backends.
Hugging Face has released LeRobot v0.4.3, adding the Unitree G1, OMX robot, and Earth Rover Mini Plus integrations and the NVIDIA IsaacLab-Arena environment, along with policies such as X-VLA, wallx, and PiFast.
Hugging Face LeRobot released v0.4.2, adding RTC real-time chunking for Pi0, Smolvla, and Pi0.5, and making parallel encoding the default across all platforms.
Hugging Face's robot learning library LeRobot has released v0.4.1, an upgrade from v0.4.0. Key updates include adding EnvHub support for loading environments from the hub, adding libero to the pypi package, fixing a training data access bottleneck to speed up training, and fixing a critical bug in dataset_tools. This version also includes a video_key spelling fix, dependency upgrades, and installation documentation updates.
