OpenAI pilots in-chat ads in ChatGPT to fund wider access

OpenAI is testing sponsored ads inside ChatGPT for users on Free and Go plans in the U.S., while paid tiers remain ad-free. The goal is to fund broader access to advanced tools; ads are described as a limited test and are shown outside responses with clear sponsorship. Users can opt out or limit ad personalization, and the rollout seeks feedback before broader deployment, with competitors already weighing in.
