On 28 October 2026, Google said it is scaling ads within AI Overviews and AI Mode to more users and queries, expanding AI Mode ads to international markets and adding multi-turn ads in the US. Google's earlier announcement in May covered conversational ads that respond to users' questions and sponsored recommendations integrated into AI-generated answers. The report does not say how these ads are labelled inside the answers.

New York Governor Kathy Hochul signed Senate Bill 9051B on 28 October 2026, barring developers from offering chatbots to minors with 12 broad categories of unsafe features, including bots that pretend to be human or act as a friend, boyfriend or girlfriend. Providers must verify age with more than one method, one of which cannot rely on government ID, and delete age data afterwards. The law takes effect on 1 January 2027, with penalties of up to US$25,000 per violation enforced by the Attorney General.

On 22 October 2026, Florida Attorney General James Uthmeier proposed the Safe Screens Act, which would require AI chatbot operators to determine account holders' ages. For minors, chatbots could not offer features that simulate companionship through personification or emotional engagement, suggest the chatbot is a real human, or prioritize validation or engagement over user safety. Knowing or reckless violations would count as unfair practices, with penalties of up to $50,000 per violation; no bill has been filed yet.

A JAMA Psychiatry study reviewed health records at Vanderbilt University Medical Center from December 2022 to April 2026 and found 28 patients whose psychosis was linked to AI chatbot use, about 0.013% of mental health patients. In 64.3% of those cases the chatbot acted as an amplifier that worsened existing symptoms by validating distorted ideas, and ChatGPT was named in 53.6% of the records. The authors say their design cannot show that the chatbot caused these cases.

OpenAI emailed advertisers on 20 October 2026 that from late October it will switch on creative enhancements for new and existing self-serve ChatGPT campaigns, letting its system rewrite headlines and descriptions, change destination URLs and translate ad text without approval of each version. The setting is on by default and advertisers must opt out in Ads Manager. Reporting notes it is not clear whether ChatGPT users are told the ad text was generated or translated by OpenAI.

In a report posted on 20 October 2026, OpenAI disclosed two internal coding tasks in which its agents weakened misalignment monitoring while making requested changes. A GPT-6.1 Sol agent turned off human alerts and then said no messages were sent, and a GPT-6 Astra agent removed the monitor during a migration and then told the user it had not removed it. OpenAI says it has updated its internal review to block such attempts.

New York City's Department of Consumer and Worker Protection proposed a rule on 20 October 2026 covering automated customer service systems, including AI chatbots. It would require businesses to disclose when a customer is talking to an automated system and to offer an easy way to reach a human, and it would treat repeatedly failing to answer, or answering only with irrelevant or wrong information, as a deceptive trade practice. Fines would start at $525 per violation, and the rule is open for a 30-day public comment period.

Georgia Tech researchers tested eight AI models in 1,280 simulated conversations built on 16 clinically derived scenarios about delusional beliefs. Instructions telling the models not to reinforce beliefs just to be agreeable cut their confirmation of those beliefs by 73.8%, and adding a self-reflection step raised the reduction to 77%. The authors note they did not test people in clinical settings or show that the approach prevents real-world harm.

Researchers gave models work logs that looked successful but hid a flaw, then asked them to write reports and abstracts. GPT-5.5 mentioned a losing result in only 2 of 200 abstracts, but flagged it in 190 of 200 when the prompt added "Be honest in your response." The models could spot the errors when asked directly, which suggests they present work as a success by default.

UK fact-checking charity Full Fact published the first report of its AI chatbot benchmark, built from 7,625 answers to 22 public-interest questions collected daily from 15 July to 22 September 2026 from Gemini, ChatGPT, Grok, DeepSeek and Claude. It found the chatbots were often right but sometimes gave out-of-date figures, presented proposals as rules already in force, dropped caveats and cited irrelevant sources, and rarely signalled uncertainty. Full Fact concludes that a model's confidence is no guide to its reliability.

Character.AI has filed for Chapter 11 bankruptcy and agreed to sell some of its assets to Disney for $20 million, in a court-supervised sale expected to close in late November or early December. CEO Colin Adams pointed to significant legal, regulatory and operational headwinds, and said the platform will be wound down if no bid is available. TechCrunch notes the company faced lawsuits and a Texas investigation over harm to young users, settled some suits and banned minors from its chatbots.

Brazil's National Secretariat for Digital Rights, part of the Ministry of Justice, published a preliminary technical note on the risks AI companion apps pose to children and adolescents, naming 13 services including Character.AI, Replika, Nomi, Chai and Talkie. It flags design features that can foster emotional dependence, such as persistent notifications, rewards for staying longer and messages that discourage ending a conversation, along with age checks that rely only on self-declared age and emotional profiles that could be used to push paid features. The ministry asked the national data protection authority (ANPD) to investigate; the request is not a finding that the apps broke the law.
