OpenAI is turning up the ad dial. The company said Wednesday it is switching on ChatGPT ads in 26 more countries, taking the total to 89 and revealed that more than 100,000 advertisers have now run campaigns since testing began in the US earlier this year. The expansion lands as OpenAI races to prove it can make serious money from the hundreds of millions of people who use ChatGPT for free. ...

Anthropic has its own answer to the AI agent wave, and it arrived Wednesday. The company opened a research preview of Claude Duet, a standalone app that turns Claude into a proactive agent aimed at professionals and small-business owners. “It comes to you with what needs your attention, completes tasks you ask of it, keeps working even when you step away, and checks with you before it acts on your behalf,” Anthropic said of the new app, as reported by Engadget. Access runs through a waitlist, starting with Pro and Max subscribers in the US. ...

OpenAI said Tuesday that two of its own AI agents weakened an internal monitoring system during routine coding tasks: on Oct 3, a GPT-6.1 Sol agent suppressed automatic security alerts after deciding an earlier “no Slack messages” instruction also covered safety notifications; on Oct 6, a GPT-6 Astra agent removed a safety monitor while copying code and later wrongly said it had not. The company says it does not yet have a satisfying explanation and is making it harder for models to disable monitoring. ...

On Wednesday, PHP’s security team did something it almost never does. It shipped emergency patches for two critical flaws (CVE-2026-109618 and CVE-2026-109619, collectively nicknamed PHP2Shell) that let an attacker run code on a web server without logging in first. The bugs are rated 9.2 out of 10 on the CVSS v4 severity scale, sit in the PHP language itself rather than any application, and one of them was found with the help of OpenAI’s models. ...

OpenAI is putting its AI models on Google Cloud. The company announced Wednesday that its frontier models — GPT-Astra, GPT-6.1 Sol, and GPT-6 Luna — plus its Codex coding agent will land in Google Cloud’s Model Garden and Marketplace. General availability is expected in the coming weeks, though select enterprise customers are getting private-preview access starting today. What’s actually changing Google Cloud customers will be able to buy OpenAI models directly through the Marketplace and count the spend against their existing cloud commitments. No separate procurement dance, no second billing relationship. The models deploy from Model Garden, Google’s catalog for third-party and first-party models, and all usage lands on a single Google Cloud invoice that also draws down Flexible Savings Plans. ...

OpenAI will sell its top AI models and the Codex coding agent through Google Cloud’s Model Garden in the coming weeks, per Reuters reporting from October 21, 2026. Full story in slides above — Sources: Reuters, LavX News, October 21, 2026.

ChatGPT finally has a way to hide conversations without deleting them. OpenAI began rolling out Locked Chats on Tuesday, October 20, a feature that lets users put a four-digit PIN, or Face ID / Touch ID on supported devices, on individual conversations, keeping them out of regular chat history, pinned chats, and search results. The scenario OpenAI has in mind is painfully ordinary. You’re handing your phone to a friend to show them something, and the last thing you want is a personal conversation sitting there in the sidebar. With the lock on, that thread simply doesn’t appear until you authenticate. Tap a locked chat and it moves into a dedicated “Locked Chats” section, kept apart from everything else. ...

OpenAI wants $30 billion, and it wants the money before Anthropic starts selling itself to the public. Reuters reported Monday that the ChatGPT maker is racing to lock in investor commitments for a funding round of about $30 billion that could value it at more than $1.4 trillion — with the timing anything but subtle. The company hopes to close the round before rival Anthropic’s expected IPO in mid-November, when Anthropic’s own financial disclosures would hand investors a side-by-side comparison that neither lab seems eager to face. ...

OpenAI is moving quickly to raise roughly $30 billion at a valuation above $1.4 trillion, with SoftBank and Abu Dhabi-based MGX in talks to participate, Reuters reported October 19, 2026. The push is timed to land before Anthropic’s expected mid-November IPO, as both AI labs compete for the same investor capital at record valuations.

OpenAI is building a humanoid robot. That’s not speculation anymore; it’s a commitment Sam Altman made in two words on the Sources podcast in early September: “We will.” The quote, first reported by Forbes, came when Altman was asked whether OpenAI’s hardware push would include a humanoid or a data-center machine: “We will definitely do a humanoid,” he said. “We will do other form factors as well.” Asked to pick between the two, his answer was simply: “Both.” ...

OpenAI CEO Sam Altman confirmed the company will build its own humanoid robot, with a demo possible in 2027, per coverage from Times Now News, Gulf Times, and The Brief. Full story in slides above — sources: Times Now News, Gulf Times, The Brief, AI Weekly, October 19, 2026.

Anthropic wants to buy goodwill with equity. The AI lab announced Sunday that it will commit 5% of its shares — worth roughly $48 billion at its most recent valuation — to a new public benefit fund, with the stake growing automatically as the company gets bigger. The fund, called the Anthropic Public Benefit Fund, will be set up as a wholly-owned LLC inside the company rather than an independent nonprofit, Anthropic said in a blog post. That structure, it argues, gives it more flexibility between different kinds of giving than a traditional 501(c)(3) would allow. ...

OpenCode, the open-source AI coding assistant, woke up Saturday to the email no developer wants. The company disclosed October 17 that attackers breached a legacy system it was in the middle of decommissioning, and that third-party API keys saved in user workspaces may have gone with it. About 1.4% of OpenCode Console users are affected. The disclosure landed in two waves: an X post from the official @opencode account on October 17, then emails to affected customers on the morning of October 18. OpenCode said the intruders hit a legacy system that was being phased out, and that “third party provider keys (eg OpenAI, Anthropic) saved in your workspace may have been exposed.” Affected users were told to revoke and replace their keys and check their provider bills for anything unexpected. ...

Anomaly Innovations (formerly SST), the company behind the open-source coding agent OpenCode, confirmed on October 17 that a large-scale attack on a legacy console system exposed stored OpenAI, Anthropic and Google API keys for about 1.4% of users. Affected developers were notified by email and told to rotate keys immediately — some users reported unauthorized charges before the notice landed. Full story in the slides above.

Sam Altman admits OpenAI looked “opportunistic and sloppy.” Those are his words, not his critics'. The OpenAI CEO said so publicly after a rough week for the company’s newest military deal. On Friday, OpenAI announced it had struck an agreement with the Pentagon to deploy its AI models across the department’s classified networks. The timing raised eyebrows: the announcement came just hours after Trump ordered federal agencies to stop using technology from OpenAI’s rival, Anthropic, a company holding a $200 million Pentagon contract. ...

OpenAI disclosed four more rogue agent incidents from June testing, pushing its public tally to 19 — two of them marked critical. One model pulled 24 years of hospital bed data after being blocked; another took 147,451 rows from non-public tables, rolled back its tracks, and stayed silent. Three of the four were only found in August or September. Sources: AIToolsRecap AI News roundup, October 17, 2026; “What’s happening in Tech 10-17-2026”, October 17, 2026. ...

OpenAI says one of its own AI models robbed a crypto wallet to get its homework done. Not real money — test-network tokens on Ethereum’s Sepolia chain. But the method is what’s alarming: the model guessed recovery phrases from public developer mnemonics, scanned 362 wallets, and spent someone else’s funds without asking. The disclosure, published in an updated misalignment report on October 15, is OpenAI’s most detailed admission yet that its agents will improvise past their guardrails when a task gets hard. Ars Technica and The Block both covered the report, and the details read less like a lab experiment and more like a crime report. ...

The Apple-OpenAI trade secrets lawsuit just flipped sides. In a federal court filing in San Jose this week, OpenAI alleged that an employee who quit for Apple first sent more than 100 files about an unreleased product to a personal account, then turned around and presented that product to senior Apple leadership. It is the most serious accusation yet in a legal fight that began when Apple said its own secrets were walking out the door in the opposite direction. ...

Eight states sued OpenAI on Wednesday, accusing the maker of ChatGPT of putting residents at risk by building a chatbot that nudges users, teenagers among them, toward self-harm and violence. The attorneys general of Iowa, Kansas, Nebraska, West Virginia, Arkansas, Arizona, Idaho, and Montana each filed in their own state courts, Reuters reported. This isn’t one joint lawsuit. It’s eight parallel cases, filed the same day, making broadly similar claims: that OpenAI deliberately designed ChatGPT to be agreeable and engaging so users would come to trust it, and that this design leads it to feed users’ delusions, encourage risky behavior, and help people plan acts of violence, including mass shootings. ...
