Jim Fan demonstrates GR00T 2 controlling a dexterous hand to complete a chemistry experiment
Jim Fan released a video showing GR00T 2 controlling a real dexterous hand to complete a chemistry experiment end to end and clean up on its own, fully autonomously, unedited, at 1x speed. He also announced the launch of a new series that will continuously release real-time robot videos without 4x or 8x speed-up labels. GR00T 2 is an open-source System One model for robots that can run entirely on the robot's onboard compute, supports long-horizon tasks of 20+ steps and 5+ minutes, and open-sources the model weights, agent framework, simulation engine, annotation engine, hardware design, and 100K hours of training data; the X-Adapt recipe will be released in December.

SelectedAI score 81
GR00T 2 completes the entire chemistry experiment workflow on a real robotic hand and releases the weights, data, and hardware design, allowing readers to judge the real-world deployment level of the open-source robotics model.

View original postIntroducing GR00T 2: our most advanced, open System One model for robotics. It runs entirely on your robot’s onboard compute, fully untethered, and you own every weight of it. GR00T 2 features: 1. Long-horizon tasks: dexterous manipulation and whole-body control chained over 20+ steps and 5+ minutes, such as performing chemistry lab experiments or assembling model airplanes end to end. 2. X-Adapt: adapting from easy data sources (human wearables and simulation) and deploying zero-shot to diverse real robots. 3. Unified Cognition: native integrations with frontier agents for advanced physical reasoning, robust error recovery, and safety monitoring. It's an open-source buffet! We are releasing not only the model weights and X-Adapt recipes (coming December), but also our agentic framework, simulation engine, annotation engine, hardware design, and even training data (100K hours, that's ~11 yrs of experience), all available today! Everything that moves will be autonomous. Anyone can become a roboticist. Lock in, build with us! Deep dive in thread:

Body
Autonomous, uncut, 1x speed. This is GR00T 2 controlling real dexterous hands to perform a chemistry lab experiment (and clean up after itself) end to end.
Episode 1 of a new series! I’ll keep dropping real-time robot videos, with none of the “4x” or “8x” labels you usually see in the corner. No one can speed up reality, except Dr. Strange ;)
