Guth Labs reports that AMD has agreed to acquire World Labs in an all-stock deal worth approximately $8.2 billion. Closing is expected by the end of 2026, subject to regulatory approval and other conditions. World Labs develops models that generate and simulate interactive environments; according to the report, AMD says that research could help guide its future technology development.

The White House announced America.gov, saying it brings answers from thousands of government websites into one place. The Tectonic, another account in the supplied posts, describes it as an AI-powered portal for federal services. Trump War Room says Trump signed an order requiring every federal agency to integrate its public-facing services with the site, potentially making it a central way Americans access government services.

Aaron Rupar quotes Trump saying he plans to sign a document renaming artificial intelligence “Super Intelligence,” while Rapid Response 47 quotes the change as already official. The wording is reaching beyond political posts: Wall St Engine quotes Elon Musk correcting “AI” to “Super Intelligence,” and the Solana account posts the new term with “Artificial” crossed out. These posts document a naming claim and its uptake, not what was signed or what practical effect it would have.

Moving Atoms announced RobotGym, describing it as a public MCP for physical-AI simulation. The company says researchers can describe or edit environments, choose from 1,246 simulation-ready environments and 90,349 physics-calibrated objects, and leave compute and GPU hosting to the platform. It also advertises “$1,000 + in GPT astra credits” for researchers helping expand the library; terms are not supplied. The pitch matters because it promises to simplify building virtual settings for testing robot behavior, including interactions with cloth, deformable plastic and fluids. In a reply, @AhmadSaroya00 said community work could help close the gap between simulation and real-world robotics. That remains an ambition: the supplied posts do not independently establish physical accuracy or successful transfer to real robots.

Cathexis Partners says it will launch ThursdAI on October 1, offering free weekly emails with “practical, responsible AI guidance for nonprofits.” The announcement is relevant to nonprofit readers seeking AI advice tailored to their sector; the post does not yet provide examples of that guidance.

Alfred Wahlforss, CEO of Listen Labs, announced that the company is joining Salesforce, bringing its AI customer-research platform into Salesforce AI Labs. Listen recruits interview participants, interviews them and analyzes their responses, according to Wahlforss. He says he will remain CEO and the same team will continue building the product, with Salesforce helping it reach more companies.

The White House announced President Trump's participation in a meeting on superintelligence. RedWave Press reports that six major AI companies signed an accord calling for internal safety controls, internal review teams, outside audits and board oversight. Those reported commitments concern how companies detect and address AI risks; Natalie Brand reports that Trump emphasized “self-policing,” while the supplied posts do not establish whether the commitments are legally enforceable.
