ByteDance has introduced an AI "brain" for robots

The TikTok-owning company ByteDance has introduced a system that acts as the "brain" for robots. It allows for the execution of household tasks such as hanging clothes or cleaning off a table.

GR-3 is a large vision-language-action model that enables bots to follow natural language commands and perform universal tasks with unfamiliar objects. They can operate in new conditions or with abstract concepts related to size and spatial relationships.

The video published on the website demonstrates how the lab's two-armed robot ByteMini can insert a hanger into a shirt and place it on a rack.

🚀🚀🚀 Ever wondered what it takes for robots to handle real-world household tasks? long-horizon execution, deformable object dexterity, and unseen object generalization — meet GR-3, ByteDance Seed’s new Vision-Language-Action (VLA) model!

In a separate technical report, the team stated that the bot handles short-sleeved clothing, although "all items in the training data were long."

Thanks to the GR-3 robot, it can execute commands to select a specific item from several and place it in the designated location.

The system is capable of recognizing an object not only by its name but also by its size (, for example, "large plate" ), or by spatial attributes (, for example, "to the left" ). It can fully carry out the task of "clearing the dining table" with a single command.

To train the model, ByteDance used a multi-component approach that included:

• joint training on large data sets in "image-text" format;
• fine-tuning on information about human action trajectories collected using VR devices;
• imitation learning setup on data about Android movements.

"We hope that the GR-3 will be a step towards creating universal robots that can assist people in their daily lives," the team stated.

Recall that in January, the startup Perplexity AI announced its intention to acquire the American TikTok. The firm sent ByteDance a proposal to combine Perplexity, TikTok U.S., and new capital partners into a single legal structure.
