Google revised a local market Super Bowl ad after Gemini showed an incorrect cheese statistic.The ad initially included a stat that Gouda made up 50 to 60% of global cheese consumption.Google has faced past criticism for inaccuracies generated by its AI.Google tweaked one of its Super Bowl ads posted on YouTube after the AI featured in it displayed an inaccurate cheese statistic.The original video showing off Google's Gemini offerings in Workspace was posted five days ago and showed the AI generating a response for a small-business owner in Wisconsin. In the response, Gemini claims Gouda accounts for "50 to 60% of the world's cheese consumption."The edited ad now shows a Gemini response that says Gouda "is one of the most popular cheeses in the world."A Google spokesperson told Business Insider that it consulted with the business owner from the ad about how he would handle the situation "after the question came up about the Gouda stat.""Following his suggestion to have Gemini rewrite the product description without the stat, we updated the UI to reflect what the business would do," the spokesperson said.A report about cheese market share published by global management consulting firm IMARC Group said that cheddar cheese "accounts for the majority of the market at around 32.4%." Gouda was not included in the report's top five by market share.Andrew Novakovic, the UV Baker professor of agricultural economics emeritus at Cornell University, told The Verge that Gouda "is almost assuredly not the most widely consumed" cheese globally.Jerry Dischler, president of Cloud applications at Google Cloud, replied to one user's post that called the stat "unequivocally false." Dischler said that Gemini's response was "not a hallucination" and that it was "grounded in the web.""In this case, multiple sites across the web include the 50-60% stat," Dischler said. "Gouda news: many love this cheese! Bada news: not everyone thinks it's as grate."The incident highlights that in addition to industry-wide risks of hallucination, AI products that are trained on or pull information from the web aren't necessarily providing fact-checked responses. The Gouda stat, for example, does exist on a website called Cheese.com.It's not the first time Google has displayed incorrect information in a video promoting its AI. Last spring, the tech giant released a promo video in which Gemini provided a list of solutions to a photographer dealing with camera issues. One of the suggested solutions would have destroyed the photographer's photos.Similarly, in 2023, a Google demo video showing off its Bard chatbot incorrectly stated the James Webb Space Telescope was the first to photograph an exoplanet. It was actually taken by a telescope operated by the European Southern Observatory, according to NASA.The tech giant also made headlines due to inaccuracies generated by its AI Overviews feature, which appears at the top of some search queries. Last year, it caused an online stir when it said to put glue in pizza sauce to prevent the cheese from falling off.Google's Super Bowl ad is a good reminder of evergreen advice that applies to anyone using AI tools: Just because an AI says something confidently, it doesn't mean that it's true.
