ChatGPT begins limited ad testing with opt-out controls

OpenAI has initiated limited testing of advertisements within ChatGPT's free tier, implementing safeguards including visible sponsorship labeling, answer integrity protection, and user privacy controls. The move aims to sustain free access while exploring monetization options, with all sponsored content remaining distinct from AI-generated responses and subject to existing privacy protocols. Users maintain the ability to provide feedback on ad relevance through the existing interface mechanisms.
