ChatGPT ads launched in five more countries

ChatGPT Ads launched in the United Kingdom, Mexico, Brazil, Japan, and South Korea on August 11. OpenAI says ads remain separate from answers, advertisers receive aggregate performance data rather than chats, and users retain controls for personalization and ad data. The expansion turns the ad pilot into a multi-market product. 1

OpenAI also made Daybreak Blue and Daybreak Red available through Amazon Bedrock. Access still requires enrollment and approval; eligible security teams can use the models inside their existing AWS governance and operations. 2

River AI, founded by former xAI co-founder Igor Babuschkin, raised $1.1 billion in a combined seed and Series A round. The company says it intends to build open models and tools for user-controlled AI, but its announcement does not yet include a shipped model, benchmark, price, or release date. 34

Stanford researchers report that 32 brokers in California's 2026 registry sell data to generative AI developers. Their review found widespread friction in privacy requests and missing disclosures, and recommends automated request tools, standardized reporting, broader registration laws, and a private right of action. 5

Tomorrow's watch item is whether ChatGPT's five new ad markets expose the same opt-out, personalization, and data-deletion controls described in OpenAI's launch note. 1
