The company first brought ads to ChatGPT in February. Until now, ChatGPT’s ads only showed a company’s name, logo, and a link to its product in a “sponsored” section beneath your chat. OpenAI’s visual ad format will similarly remain separate from the image you generate and will “not influence the answers ChatGPT provides.” Ads won’t appear if you subscribe to ChatGPT’s Plus, Pro, or Enterprise plans.
