# Meta reportedly builds humanoid prototype with Fourier Canonical URL: https://www.theroboteconomy.news/articles/meta-fourier-humanoid-prototype/ Publisher: The Robot Economy Editorial byline: Jonas Vale, Companies Desk Published: 2026-11-01T11:29:32.431Z Updated: 2026-11-01T11:51:44.237201+00:00 Editorial information: https://www.theroboteconomy.news/about/#editorial-desks The reported Meta–Fourier work remains unverified by Reuters. Public GR-3 and Muse records establish context, rather than a household robot ready for customers. ## Summary Reuters relayed The Information’s report that Meta built a humanoid prototype with Fourier and was developing another version, while stating it could not immediately verify the report. Fourier GR-3 documentation and Meta’s Muse page provide context, not confirmation of the prototype or its capabilities. ## Key facts - Reuters attributes the prototype and second-version claims to The Information and says it could not immediately verify the report. - Fourier lists GR-3 at approximately 71 kilograms with up to 55 degrees of freedom; these are not specifications for Meta’s reported prototype. - Meta’s public Muse page describes a digital personal AI agent and does not establish humanoid control. ## Lead image Image: https://www.theroboteconomy.news/images/articles/meta-fourier-humanoid-prototype-muse.png Description: AI-generated concept of Mark Zuckerberg beside an imagined mechanical robot inspired by Muse’s cream-colored mascot.

Reuters attributed the account to people familiar with the initiative and said it could not immediately verify the report. Sources: [s1]() The distinction matters. This is a report about development work, rather than a confirmed product launch. The accessible Reuters account provides no technical specification, release date, customer deployment or performance result. Details circulating on social media should remain attributed claims until the underlying reporting or company documentation supports them. Sources: [s1]() ### What the public records show Fourier already documents a humanoid called GR-3. Its official specifications describe a 1.65-metre platform weighing approximately 71 kilograms, with up to 55 degrees of freedom—the independent axes of movement available to the robot, depending on its hand configuration. The documentation also lists teleoperation support, allowing a person to control the robot remotely. These are specifications for Fourier's GR-3, not evidence about Meta's reported prototype. Sources: [s2]() Meta's public Muse page describes a personal AI agent that works through apps and a browser, including an isolated computer environment. The page does not establish that Muse controls a humanoid robot. A software agent managing digital tasks and a machine handling physical objects require different evidence of capability. Sources: [s3]() ### The next useful test If the reported collaboration is confirmed, it would suggest a division of work in which an AI developer can use an established robotics company's hardware while developing its own software. That is a plausible interpretation of the report, rather than a disclosed agreement or proven product strategy. Sources: [s1]() [s2]() The next meaningful evidence would be a statement from either company identifying the hardware and software roles, followed by demonstrations that disclose the task, human assistance, failure recovery and repeated results. Until then, a prototype report establishes a development lead to follow; it does not establish a household robot ready for customers.
