Meta has built a prototype humanoid with Fourier in about three months, and the two are already working on a second version. The robot, known internally as Max, weighs about 48kg (106 pounds) and stands about 1.5 metres tall. It runs on Nvidia’s Jetson Thor chip and includes a face screen, built-in speakers and five-fingered hands capable of picking up small objects. Meta’s robotics team travelled to China to collaborate with Fourier, with Li-Chen Miller, Meta’s vice president of product for robotics, spending almost two months at Fourier’s Shanghai factory. Meta demonstrated Max to staff at an internal robotics summit in late August. Work on Max 2 began in September, and the second version is slated to feature a new torso, better hands, a projector and extra sensors to help with stairs. Meta frames humanoids as a physical form for Muse, its AI agent, with interest in using them for household tasks. Nvidia recently agreed to invest $3 billion in Meta and expand collaboration on Muse. Meta has been expanding its robotics capabilities, including acquiring Assured Robot Intelligence in May, a move that brought AI software for robots into its fold. Fourier is based in Shanghai and unveiled GR-3, described as a “care-bot,” in August 2025. The tech landscape for humanoid development includes other players pursuing home and factory robots, such as Tesla’s Optimus and Agility’s Digit 5, with rival Chinese makers pursuing AI self-improvement for robots. Meta has not announced a launch date for a humanoid product.
