On Monday, OpenAI officially commenced ad testing within ChatGPT, according to anonymous insiders. Earlier, OpenAI had made a public commitment that any advertisements would be distinctly marked. These ads would solely appear at the end of the chatbot's responses and would not interfere with the quality or content of the replies. Looking ahead, OpenAI anticipates that advertising revenue will constitute less than half of its total income. At present, the digital advertising landscape is largely controlled by Google and Meta, although Amazon has also seen a notable surge in its market share in recent times. Notably, Anthropic took a jab at OpenAI's move by running ads during the Super Bowl, mocking the decision to introduce advertisements. In response, executives like Altman took to social media, labeling the ad content as 'misleading' and reiterating that OpenAI would not implement ads in the way Anthropic suggested.
