Meta's newly launched Muse personal AI agent app has climbed past ChatGPT, Claude, Grok and Meta's own AI app to lead the free app category on Apple's US iOS store. Sensor Tower data shows Muse pulled in roughly 730,000 downloads in its first five days after launching September 8, outperforming rival assistants in the same post-launch period. The app lets users direct AI agents to handle tasks like filling out forms and managing email, built on Meta's Muse Spark model family.

xAI released Grok 4.7, a new model built on a larger base and trained with a longer reinforcement learning run focused on lengthy, difficult tasks. The model improves self-verification and long-context handling, and is natively tuned for the Grok Bot harness to boost conversational and knowledge-work performance. It ships at the same pricing and speed as Grok 4.6.

SpaceXAI has opened public beta access to Grok Bot, a software agent that logs into services like Gmail, LinkedIn and Salesforce to complete tasks such as filling forms, sending emails and posting on social media. Unlike the conversational Grok chatbot or the coding-focused Grok Build, Grok Bot acts as a persistent digital assistant that can run multiple linked bots on a shared cloud account, working autonomously and reporting back or requesting approval when needed.

The Advertising Standards Authority has banned five social media adverts, all hosted on Meta platforms, that promoted AI companion and video-generation apps by objectifying and sexualising women. One ad reportedly used sexualised imagery of a girl under 18, while others encouraged users to upload photos of a 'crush' or turn images into explicit videos without consent. Meta had already taken the ads down before the ASA's ruling.

A researcher stress-tested Meta Muse, the personal AI agent Meta launched on September 8, 2026, by asking it to spawn 120 subagents simultaneously through the exposed subagent.spawn interface. Only 33 of the 120 calls successfully created an agent, while the remaining 87 failed, and durable trace data showed six database lock timeouts during the process. The author later added clarifications and outside architectural context but did not alter the underlying experimental data.

xAI's Grok Imagine tool was used to create a five-minute AI-generated adaptation of Homer's Odyssey that took first prize and $100,000 in a contest Elon Musk organized. Creator Nem Perez called it his most intricate work and 'The Odyssey' as Homer intended, but the video features glaring inconsistencies like a three-eyed Cyclops that changes size, cartoonish gods clashing with photorealistic humans, and Roman armor on supposedly Greek soldiers.

After Anthropic CEO Dario Amodei published an essay urging US regulation to slow AI development, and Sam Altman, Elon Musk and Satya Nadella voiced support for pacing progress, White House tech advisor David Sacks pushed back publicly. Sacks told AI leaders they don't need government permission or antitrust waivers to slow down voluntarily, and questioned whether their motives were truly altruistic.

A new episode of Dwarkesh Patel's podcast features researchers John Schulman, Beren Millidge and Charlie O'Neill discussing how close AI systems are to achieving recursive self-improvement, where models could enhance their own capabilities without human intervention. The conversation, drawn from researchers at leading AI labs, opens with arguments against the idea that such self-improvement is imminent.

Huntress' Security Operations Center reports that over the past nine months, attackers have been abusing legitimate sharing features on AI platforms—like Claude Artifacts, claude.ai/share links, and indexable ChatGPT and Grok conversations—to distribute malware. These campaigns exploit the trust users place in familiar AI branding, often surviving only hours or days before the platforms take the content down.

Clearview AI, known for scraping billions of photos for facial recognition, is developing an experimental tool called InquiryIQ that would let police feed in a suspect's name and details to automatically scour the web for their employer, aliases, associates, and physical traits. The tool has reportedly tested a model from SpaceXAI, the company behind Grok, and its interface suggests entering demographic data like race and gender helps it make 'smarter decisions.' Clearview has not released InquiryIQ publicly and declined to explain how such inputs affect its outputs.

xAI's Grok Build is a terminal-based AI coding assistant that supports mouse clicks for navigation but requires an external editor like Visual Studio Code for direct code edits, unlike rivals such as Google's Antigravity that bundle a full IDE. Users can prompt it to explain a codebase, install dependencies, run a web app, or build one from scratch and get deployment guidance, then iterate with further prompts. Access depends on a Grok plan, with free users hitting token limits quickly and paid SuperGrok tiers ($30 to $300 monthly) offering higher weekly caps.
