Overview
- OpenAI began serving ads to some U.S. users of ChatGPT on Monday, initially targeting Free and Go tiers with clearly labeled placements at the bottom of responses.
- The company says ads won’t appear for users it identifies as under 18 or next to sensitive topics such as health, mental health or politics, and Plus and Pro subscribers remain ad‑free.
- Targeting will draw on current and previous chats and user interactions with ads, with no use of off‑platform data for now, and OpenAI says ads will not influence ChatGPT’s answers.
- Sam Altman told employees ChatGPT is back to exceeding 10% monthly growth and previewed an updated chat model slated for release this week, with reported weekly active users topping 800 million.
- Altman said Codex usage grew about 50% week over week after the GPT‑5.3‑Codex launch, and CNBC reported OpenAI is in talks on a roughly $100 billion funding effort that remains fluid.
