The initial test will use a first group of advertisers and place visual ads during image generation in ChatGPT. OpenAI says the ads will not influence ChatGPT’s answers and will remain separate from the image a user is creating. The company is also expanding conversion and attribution integrations, including Hightouch, Tealium, LiveRamp, AppsFlyer, Adjust, Branch, and other partners. For users, the confirmed rollout details are limited to a US test beginning later in October 2026 during image generation; OpenAI has not published the exact launch date, which ChatGPT plans or accounts will be included, or the size of the test.
