OpenAI says ChatGPT Ads has reached a $1 billion annualized run rate

OpenAI · August 31, 2026

OpenAI published a milestone update on its advertising business, saying ChatGPT Ads crossed $1 billion in annualized revenue run rate in under 200 days and is now used by tens of thousands of advertisers. Self-service buying through Ads Manager begins rolling out across India, Europe, the Middle East and North Africa, adding to availability in more than 40 countries through OpenAI’s sales team and partners. The company frames advertising as one pillar of a diversified model alongside subscriptions, enterprise and API revenue, and says the ad-supported free tier is what keeps ChatGPT available to more than 1 billion weekly active users. OpenAI reiterates that ads are labeled, kept separate from answers, and do not influence what ChatGPT says, and that advertisers do not get access to private conversations.

Tencent open-sources Hy4 preview, a 770B model that helped optimize its own training

Tencent · August 28, 2026

Tencent released and open-sourced Hy4 preview: 770B total parameters, 49B active, and a context window exceeding 1M tokens, available on Hugging Face and through WorkBuddy, CodeBuddy, Yuanbao and ima, with API access via Tencent Cloud TokenHub and OpenRouter. In an internal blind evaluation using 163 experts across 203 engineering tasks, Tencent scored the model at 2.99/4.00, narrowly ahead of GLM-5.3 (2.92) and Kimi K3 (2.94). The most striking claim is recursive: Tencent says the model participated in the automated optimization of its own training methods, data strategies, evaluation frameworks and low-level operators, and separately analyzed bottlenecks in its own inference system to deliver a measured 31.8% end-to-end throughput gain. API pricing is $0.834 per million input tokens and $2.501 per million output tokens, with the model free on WorkBuddy and CodeBuddy for two weeks.

“Notably, Hy4 preview also contributed to its own development process, participating for the first time in the automated optimization of training methods, data strategies, evaluation frameworks, and low-level operators. … This established an early-stage recursive self-improvement loop.” — Tencent

Thirty-five music publishers sue Anthropic, Amodei and Mann over training data

U.S. District Court, N.D. Cal. · August 28, 2026

Thirty-five music-publishing entities, including affiliates of Sony Music Publishing and Warner Chappell Music, filed a copyright suit against Anthropic, CEO Dario Amodei and co-founder Benjamin Mann in the Northern District of California (case no. 5:26-cv-09217). The complaint alleges Anthropic acquired copyrighted compositions at scale through torrenting and mass scraping, including from shadow-library sources, and identifies “tens of thousands” of allegedly infringed works — a far broader set than the 500 songs at issue in the earlier Concord Music Group action. Plaintiffs seek statutory damages of up to $150,000 per willfully infringed work plus up to $25,000 for each removal of copyright management information, destruction of infringing copies, and an accounting of Claude’s training data. Anthropic says it disagrees with the claims and intends to defend itself in court. The filing itself is the primary source here; it is not yet indexed on public docket mirrors, so the summary below reflects the complaint as reviewed and reported by trade press.

OpenAI and Thailand’s science ministry launch a startup accelerator

OpenAI · August 28, 2026

OpenAI and Thailand’s Ministry of Higher Education, Science, Research and Innovation announced an eight-week accelerator in Bangkok for ten startups in health, wellness and education — OpenAI’s first public-private partnership with the Thai government aimed at local startups. Each team gets $2,000 in API credits, a dedicated mentor, and weekly sessions on evaluation, responsible AI, privacy and cost management, with a Demo Day in November. OpenAI says Thailand ranks in the global top 20 for both ChatGPT weekly active users and Codex usage, with Codex usage up more than 350-fold since the start of 2026.

“We believe the biggest breakthroughs don’t usually come from platform companies themselves, but from founders who deeply understand a problem and build something people value.” — Sandy Kunvatanagarn, Head of Policy for ASEAN, OpenAI

A federal judge voids the Pentagon’s “supply chain risk” label on Anthropic (August 27, 2026) — just outside the window, U.S. District Judge Rita Lin ruled in the Northern District of California that the Department of War’s designation of Anthropic as a supply-chain risk was unlawful retaliation under the First Amendment and denied the company Fifth Amendment pre-deprivation process, calling the decision arbitrary and capricious. Anthropic’s parallel D.C. litigation is still pending, so the designation is not fully lifted. Source: NPR — Judge says Pentagon’s measures against Anthropic were ‘illegal and baseless’
