An anonymous reader quotes a report from the Wall Street Journal: Mark Zuckerberg wants everyone inside and outside his company to eventually have his or her own personal artificial-intelligence agent. He is starting with himself. Zuckerberg, the chief executive of Meta Platforms, is building a CEO agent to help him do his job (source paywalled; alternative source), according to a person familiar with the project. The agent, which is still in development, is currently helping Zuckerberg get information faster -- for instance, by retrieving answers for him that he would typically have to go through layers of people to get, the person familiar with the project said. [...] Use of AI tools has spread quickly through the ranks at Meta -- in part because it is now a factor in employees' performance reviews. Meta's internal message board is filled with posts from employees sharing new AI use cases they have found and new tools they have built using AI, according to people familiar with the matter. [...] Employees have started using personal agent tools such as My Claw that have access to their chat logs and work files and can go talk to colleagues -- or their colleagues' own personal agents -- on their behalf, the people said. Another AI tool called Second Brain that is somewhere between a chatbot and an agent is also gaining momentum internally, according to people familiar with the matter. Second Brain was built by a Meta employee on top of Claude and can index and query documents for projects, among other uses. On the internal post announcing it to staff, the employee said it is "meant to be like an AI chief of staff." There is even a group on the internal messaging board where employees' personal agents talk to each other, some of the people said. (Separately, Meta acquired Moltbook, the social-media site for AI agents, and hired its founders in a deal earlier this month.) Meta also recently acquired Manus, a Singapore-based startup that makes personal agents that can execute tasks for its users, and is using the tool internally, some of the people said. Meta recently established a new applied AI engineering organization that is tasked with using AI to help speed up development of the company's large language models. Those teams will have an ultraflat structure of as many as 50 individual contributors reporting to one manager, The Wall Street Journal previously reported. [...] Employees across the company said they have been encouraged to attend AI tutorial meetings several times a week and frequent AI hackathons, and to create their own AI tools to speed up their work.

Meta is partially reversing its decision to drop VR support for Horizon Worlds, keeping VR access for existing Unity-based games while shifting future development to a new flatscreen-focused Horizon Engine. UploadVR reports: If you somehow missed it, on Tuesday Meta officially announced that its Horizon Worlds "metaverse" platform would drop VR support in June, meaning it would only be available as a flatscreen experience for the web and smartphones. But now, in an "ask me anything" session on his Instagram page, Meta CTO Andrew Bosworth says the company has decided to "keep Horizon Worlds working in VR for existing games to support the fans who've reached out." Bosworth says this specifically applies to worlds developed with the Horizon Unity runtime, suggesting it applies to those built inside VR or with the Horizon Desktop Editor, but not those built for the new Horizon Engine with Horizon Studio. The picture painted here is of a clean technical break, with the legacy Unity version of Horizon Worlds continuing to support VR, and the new Horizon Engine focusing fully on flatscreen. This VR support will continue through the Horizon Worlds VR app, which Bosworth says will stay on Quest's store "for the foreseeable future". Specific worlds will not be recommended by the operating system, though, and nor will they be seen in the storefront. Horizon Worlds will be just another app on the store. As for the reason behind not supporting VR in Horizon Engine, Bosworth repeated the explanation he's been giving for two months now -- "because that's where most of the consumer and creator energy already was, and so we're leaning into that."

Meta is shutting down its VR social platform Horizon Worlds, which was once a key piece of the pivot to the metaverse. The company said the app will be taken off the Quest store at the end of March, and fully removed from Quest headsets by June 15. After that date, it will shift to a standalone "mobile-only experience." CNBC reports: The shift for Horizon Worlds, which was once a central part of the company's push into virtual reality, comes weeks after Meta cut over 1,000 employees from Reality Labs, the unit responsible for the metaverse. [...] The social platform has never drawn more than a couple hundred thousand active users a month, CNBC previously reported. The virtual 3D social network where avatars could interact and play games with other users officially launched in late 2021. It operated exclusively on the Quest VR platform until Meta launched a mobile app version in September 2023. The mobile version of Horizon Worlds was built to provide an entry point for users without VR headsets, functioning similarly to Roblox.
