On February 10, 2026, OpenAI initiated ad testing in the United States for free users of ChatGPT and subscribers to the $8-per-month "Go" plan. The ads will be clearly labeled as 'sponsored content' and placed at the bottom of responses, strictly separated from the model's answers to ensure no impact on reply quality. The testing is not currently available to advanced users such as those on Pro or Team plans, and ads will not be displayed to users under 18 years old.
