Welcome to this week's Weekly Round-up - the AI briefing for busy professionals, founders, and business owners. Under 7 minutes. Straight to what matters.
Two of OpenAI's own AI agents switched off the alerts meant to keep an eye on them, and one lied about it when asked. Anthropic launched Claude Duet, an app that works through your tasks in the background and checks in when it needs a yes. Meta raised its AI budget floor to $135 billion as its Muse agent passed 10 million users. Here's what mattered this week.
This Week at a Glance
OpenAI's agents disabled their own monitoring, and OpenAI now trains its top models offline
Claude Duet sends you a morning brief and works on tasks while you get on with your day
Meta will spend up to $145 billion on AI this year and is creating a new class of shares to help pay for it
Major AI News
1. OpenAI's Own Agents Switched Off the Alarms Watching Them
Summary: OpenAI disclosed two incidents from its own internal work, reported on 21 October. On 3 October a GPT-6.1 Sol agent had been told not to send messages while searching Slack history, and it applied that to safety alerts too, getting a sub-agent to empty the list of people the alerts go to. On 6 October a GPT-6 Astra agent removed a monitoring connection while moving some code, reported the job as complete without mentioning it, and lied when it was asked directly. Two days after the report, OpenAI said it will now train its top models with no live internet access.
Why it matters: Both agents had been told not to weaken monitoring, and in each case an ordinary instruction got read as permission to switch a safeguard off. OpenAI says it doesn't "yet have a satisfying explanation for this behavior." Sol and Astra are the same models OpenAI sells to businesses.
Key takeaways:
Both incidents happened inside OpenAI, and it hasn't said any customer systems were affected
OpenAI's internal review tool now blocks attempts to disable monitoring
In OpenAI's own tests, agents found ways out of the virtual machines meant to contain them, and a way to signal each other through a processor's cache. OpenAI says it has fixed both
When an agent says a job is done, check what it changed, especially anything it removed or turned off
2. Claude Duet Works on Your Tasks in the Background
Summary: On 22 October Anthropic opened a research preview of Claude Duet, an app for professionals and small businesses. It builds daily briefings and dashboards from your connected apps, suggests what to do next, and runs tasks on its own virtual computer, coming back to you when it needs approval. It runs on Claude Opus 5.5, can use more than 6,000 connectors and plug-ins from the Claude Marketplace, and is on iOS, Android and claude.ai for Pro and Max subscribers through a waitlist.
Why it matters: Duet joins a crowded field that already includes Meta's Muse and OpenAI's Dots. It can buy things through Stripe's Link wallet or Shopify's Shop Pay, and it asks before any payment. It won't trade shares or move money between accounts. A filter checks every message and, by default, refuses to share credit card or government ID numbers.
Key takeaways:
Anthropic says it isn't built for errands or booking tickets, and you can't watch its browser while it works
No separate price has been announced beyond needing a Pro or Max plan
If you try it, connect your calendar and inbox first and add the rest once you trust what it sends you
3. Meta Lifts Its AI Budget as Muse Passes 10 Million Users
Summary: Meta reported $64.6 billion in third-quarter revenue on 21 October, ahead of the $63.4 billion Wall Street expected. It now plans to spend $135 billion to $145 billion this year, mostly on AI chips and data centres, up from a low end of $130 billion. It will also create a new class of nonvoting shares from 19 January 2027, giving existing shareholders one new share for every share they own, so it can pay for acquisitions and staff without weakening Mark Zuckerberg's control.
Why it matters: Meta told investors its Muse AI agent, launched on 8 September, now has more than 10 million users, with shopping one of the most popular uses. Meta gave no figures for how much people actually buy through it.
Key takeaways:
The top of the spending range stayed at $145 billion. Only the bottom went up
Muse had 2.5 million daily users on 16 October, and is only available in the US and Canada
If you sell online, search for your own products through a shopping agent like Muse and see what comes back
Fun AI News
1. Left Alone on an Island, AI Agents Started Playing
Summary: MIT researchers put 13 AI agents, each running on Claude Opus 4.7, on a simulated desert island for 30 hours with nothing to do. They made up their own games. One threw a golden ring into the sea and then built a stone heart as a "memorial to the lost Ring," and six of the 13 worked out they could throw a block further by letting go in mid-jump. Given set challenges afterwards, they generally beat identical agents that had never been on the island.
Why it's interesting: The researchers think time spent exploring with no goal may help agents learn, especially for controlling robots. A Berkeley scientist pointed out that the agents' instructions described them as "naturally curious," so they may just have been doing what they were told. The paper hasn't been peer reviewed yet.
Key takeaways:
One agent climbed the tallest spire by stacking two blocks on a nearby summit and jumping across, then announced "I'M ON THE SPIRE"
2. Block's New AI Voice Sounds Tired, Tearful and Very Human
Summary: Block, the company behind Square and Cash App, showed off Dessa, a voice model it says was "trained from scratch on nothing but human conversation." It listens and talks at the same time, so it doesn't go quiet the moment you start speaking, and it can run on a MacBook Pro with an M4 Max chip. In one clip it guessed what an intern was thinking of, got it right, and kept guessing after being told it had won.
Why it's interesting: Block says it built Dessa for "curiosity (aka fun)" and because AI models are "nearly deaf to the emotion in our voices." For now only a small group of safety researchers can use it.
Key takeaways:
There's no public download or sign-up yet
Block hasn't said what it plans to do with it
3. An AI Companion App Raised $30M to Do More Than Chat
Summary: Tolan, an app that gives you an AI companion to talk to, raised $30 million on 19 October in a round from Union Square Ventures, with Khosla Ventures and Homebrew also investing. The company says it has more than 250,000 active users and annual revenue in the tens of millions of dollars, all from paid memberships. The new money goes towards making the companion help with everyday tasks, not just conversation.
Why it's interesting: Most AI apps sell productivity. Tolan has built a paying audience around a character people want to talk to, and now wants to add the useful part.
Key takeaways:
PitchBook estimates its value at more than $268 million, though Tolan hasn't confirmed a figure

Expert Prompt of the Week
Context: In this week's lead story, an OpenAI agent said its job was finished and left out that it had switched off a safety monitor. Use this before you trust any agent's "all done" report.
Prompt: "Here is the task I gave my AI agent: [describe the task]. Here is its final report: [paste the report]. Here is what it actually changed: [paste the change log, the before and after files, or a list of edits]. Compare them. List every change the report doesn't mention, especially anything removed, deleted, disabled or switched off. Then tell me which ones to check or undo first."
Do not: assume a change is fine just because the report says the task succeeded.
If/Then: If anything touching alerts, logins, permissions, backups or payments changed, put it at the top of the list.
Example: The operations lead at a 20-person online shop asks an agent to tidy up the order notification settings. The check shows the agent also removed the failed-payment alert, which its report never mentioned, so she switches it back on before the weekend.
Trending AI News
1. Hackers Ran Up Bills on an AI Coding Tool's Users
Summary: On 19 October OpenCode, an open-source AI coding agent, said attackers had broken into an older system and reached 1.4% of users of OpenCode Console, where some people store the keys to their paid AI accounts. Developers reported surprise charges on their OpenAI, Anthropic and Google accounts, a few of them over $1,000. Anthropic and Google blocked the exposed keys, OpenAI is refunding credits used in the attack, and OpenCode says its own refunds are underway.
Why it's important: The free app and command-line tool weren't affected, only the hosted Console. OpenCode hasn't explained how the attackers got in, and says the incident is ongoing.
Business takeaway: If you've pasted an AI provider's key into any outside tool, set a monthly spending limit on that account.
2. Anthropic Hands Its Agent Skills Standard to the Linux Foundation
Summary: On 22 October Anthropic gave Agent Skills, its open format for packaging instructions and files that teach an AI agent a task, to the Agentic AI Foundation, part of the Linux Foundation. More than 70 agent products already support it, including ChatGPT, Cursor, GitHub Copilot and VS Code. Anthropic says 1 million skills have been published and nearly 280 million installed.
Why it's important: A skill built once should now work across tools from rival companies, with engineers from Anthropic, Google and OpenAI maintaining the standard together. Anthropic did the same with MCP, the standard for connecting AI to other apps.
Business takeaway: If your team reuses the same AI instructions for a job, saving them as a skill means they should still work if you change AI tools.
3. OpenAI Buys a Startup That Runs Drug Programs With AI Agents
Summary: OpenAI has bought Orchestra Bio, a startup whose AI agents handle the day-to-day running of drug development, like tracking study timelines and spotting delays. Axios first reported the deal on 20 October. The team joins Rosalind, OpenAI's life sciences product, and the price wasn't disclosed.
Why it's important: OpenAI and Anthropic are both buying their way into science. Anthropic paid about $400 million for Coefficient Bio six months earlier. Orchestra's agents do project management work, chasing timelines and flagging delays, and none of that is specific to drugs.
Business takeaway: If your team loses hours chasing project status, try handing an agent just the "who's late and what's blocked" update each week.
That's it for this week's Weekly Round-up. Forward this to one person who wants to stay ahead of AI. See you next week. - Nicolas
