OpenAI begins testing advertisements in the U.S. for its Free and $8/month Go subscription tiers, excluding paid plans like Plus and Business. CEO Sam Altman assures users that ads won’t influence AI responses or compromise privacy, stating, “Ads do not influence the answers ChatGPT gives you.” Critics worry about user experience, especially after a backlash last year. Users will have transparency and control over ads, which won’t appear for those under 18 or around sensitive topics.
