OpenAI is testing ads in ChatGPT for both free and $8/month Go subscribers in the U.S. Google, however, has stated that its AI model, Gemini, will not include ads at this time. Demis Hassabis, CEO of Google DeepMind, acknowledged the early decision by OpenAI to incorporate ads, suggesting it may stem from a need for additional revenue. While Gemini's current ad-free status is confirmed, Google has left open the possibility of future ad integration. The ads in ChatGPT appear at the bottom of responses when they relate to the conversation topic, and users can provide feedback or dismiss them. Notably, there will be no ads in discussions about sensitive topics like health and politics. Meanwhile, paid subscriptions like Plus and Pro will remain ad-free, indicating a strategic approach to balancing revenue generation with user experience.
