OpenAI is testing ads in ChatGPT for U.S. users on free and lower-tier subscriptions. The ads will not affect response quality and user privacy is maintained, with no access to chats by advertisers. Users can opt out of ads through subscription upgrades or by limiting daily messages.

OpenAI outlines its approach to integrating ads into ChatGPT while ensuring user trust and privacy. The company emphasizes that advertising will not influence responses and offers users control over data and ad personalization. The initiative aims to expand access to AI tools while maintaining a commitment to user experience.
