Description
GR-Dexter is a robot foundation model from ByteDance Seed, the AI research team of TikTok’s parent company. The team introduced it in December 2025 to tackle one of robotics’ hardest problems: dexterous hands. Most robot models control simple two-finger grippers. GR-Dexter, however, controls two human-like hands with five fingers each. It’s a vision-language-action model, so it turns camera images and spoken instructions into precise hand movements. In addition, it builds on ByteDance’s earlier GR-3 model.
ByteDance paired the model with its own ByteDexter robotic hand, which has touch sensors in the fingertips. The team trained GR-Dexter on several kinds of data. These include remote-controlled robot demonstrations, data from other robots and videos of people using their hands. As a result, the model copes well with objects and instructions it has never seen. For example, it tidied makeup items, used a vacuum and served bread. Moreover, it stayed reliable when the scene changed in unexpected ways.
