Rabbit launches OS3, an AI agent that runs without its R1 hardware

Rabbit has released OS3, a cloud-based 'agentic operating system' that works locally on Windows, Mac and Linux machines rather than requiring its R1 device. Users can link up to five devices and preferred AI models, and access OS3 via a desktop site, messaging apps like Telegram or iMessage, or the R1. Founder Jesse Lyu told Wired that Rabbit has stopped manufacturing the R1 but is developing a new 'cyberdeck' device to run OS3 within months.

Rabbit relaunches as OS3, an AI agent platform beyond its R1 gadget

Rabbit, the startup behind the widely panned R1 hardware assistant, has introduced OS3, an 'agentic operating system' that can run across a desktop browser, Telegram, or iMessage rather than requiring the original device. CEO Jesse Lyu says the R1 sold over 100,000 units with strong margins despite the harsh reviews, and now sees the software-first approach as timed to a market that has caught up to what Rabbit tried in 2024.

TechCrunch Disrupt 2026 to feature five AI safety sessions for founders

TechCrunch has outlined five sessions at its 2026 Disrupt conference focused on AI safety and security, spanning the AI Stage and Real World AI Stage.

Meta's Muse AI assistant sparks privacy backlash over unauthorized data access

Meta is heavily promoting Muse, a new AI agent for Instagram and Facebook users that links to email, bank accounts, and other personal data to automate tasks and build a long-term memory of user habits. Multiple users, including a journalist at Inc Magazine, reported that Muse surfaced private text message content despite never granting it permission to access Messages, and Meta's own staff gave conflicting, unconvincing explanations for how this happened.

Meta fixes zero-day flaw in Muse macOS app after researcher hijacks AI agent

Security researcher Patrick Wardle found an unpatched setting in Meta's Muse macOS app that let local attackers reroute the app's cloud-based dictation to their own server, effectively seizing control of the AI agent. Wardle demonstrated the flaw by using Muse's own privileges to snap photos and write files to disk, often without alerting the user. Meta issued a hotfix within hours of the report, though it maintains the exploit required existing local access and posed low real-world risk.

Meta's Muse AI app tops iOS charts as Amazon blocks it from its store

Meta's new personal AI agent app, Muse, has become the top free iOS app in the U.S. with over 2.5 million downloads in under two weeks, surpassing ChatGPT and other rivals.

Forcepoint Warns AI Agents Can Cause 'Denial of Wallet' Cost Overruns

Forcepoint published research showing how AI applications lacking limits on compute and resource usage can rack up massive, unbudgeted bills, a vulnerability now ranked sixth on OWASP's 2026 Top 10 for LLM Applications. Researcher Jyotika Singh outlined five scenarios, including leaked API credentials being used to flood pay-per-use AI services with requests, driving costs far past expected budgets.

Amazon blocks Meta's Muse AI agent from shopping on its site

Amazon has cut off access for Meta's newly launched Muse AI shopping agent, showing users a pop-up citing violations of its Conditions of Use. Muse, introduced on Sept. 8, was designed to handle tasks like online purchases, but Amazon says unauthorized third-party agents must operate transparently and respect merchants' choice to participate.

Meta's Muse AI agent app surpasses ChatGPT in US iOS downloads within two weeks

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.
