## Summary

Jim Fan posts an uncut, real-time video of GR00T 2 controlling dexterous hands to complete a chemistry lab experiment and clean up afterward. The quoted announcement says GR00T 2 runs fully on the robot's onboard compute, with model weights and X-Adapt recipes due in December and other components available today.

## Why it matters

The quoted announcement details an open model's untethered onboard deployment, long-horizon task chaining, and released training data, useful for judging robotics open-source practice.

## Post

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 ;)

## Quoted post @DrJimFan

> Introducing 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!
