ChatGPT's ad pilot has the industry excited, but some insiders are frustrated with the slow rollout

When OpenAI first announced it was rolling out ads on ChatGPT , brands and agencies across Madison Avenue were eager to test the new format to figure out their artificial intelligence advertising strategies. The high-profile announcement, which was far more public than a typical "alpha" test of a new format, presented a massive opportunity. Three of the world's largest ad agencies are part of the testing program, including WPP, Omnicom and Dentsu . So far, the test is moving too slowly to meet the hype, according to multiple ad industry sources who spoke on condition of anonymity in order to discuss the details. The sources told CNBC that OpenAI's test program is frustrating many of its partners because of the conservative rollout.

For some brands, this money came from funds dedicated to innovative new formats, while others drew from search or social ad budgets. With the pilot program running through the end of March, some of the sources told CNBC they are concerned with the slow pace of rollout, which means their full budget commitments are unlikely to be spent by the end of the month. While any excess will be returned, the budget was already committed to the trial and so can't be deployed elsewhere during the quarter. Advertisers also won't get the volume of insights they were hoping for. Omnicom did not return requests for comment. WPP declined to comment. OpenAI told CNBC that the slow rollout of the ads program was intentional. "We're in the early testing phase of ads in ChatGPT, and the goal right now is to learn and refine the experience for consumers before expanding it more broadly," the company said. "We're encouraged by early signals from users and participating brands, and continue to see strong interest from advertisers." Japanese ad ...
