Within the case of AI Overviews’ advice of a pizza recipe that comprises glue—drawing from a joke publish on Reddit—it’s seemingly that the publish appeared related to the consumer’s unique question about cheese not sticking to pizza, however one thing went unsuitable within the retrieval course of, says Shah. “Simply because it’s related doesn’t imply it’s proper, and the technology a part of the method doesn’t query that,” he says.
Equally, if a RAG system comes throughout conflicting info, like a coverage handbook and an up to date model of the identical handbook, it’s unable to work out which model to attract its response from. As a substitute, it could mix info from each to create a doubtlessly deceptive reply.
“The massive language mannequin generates fluent language primarily based on the supplied sources, however fluent language will not be the identical as appropriate info,” says Suzan Verberne, a professor at Leiden College who focuses on natural-language processing.
The extra particular a subject is, the upper the prospect of misinformation in a big language mannequin’s output, she says, including: “It is a downside within the medical area, but additionally training and science.”
In response to the Google spokesperson, in lots of instances when AI Overviews returns incorrect solutions it’s as a result of there’s not a whole lot of high-quality info out there on the internet to indicate for the question—or as a result of the question most intently matches satirical websites or joke posts.
The spokesperson says the overwhelming majority of AI Overviews present high-quality info and that most of the examples of unhealthy solutions had been in response to unusual queries, including that AI Overviews containing doubtlessly dangerous, obscene, or in any other case unacceptable content material got here up in response to lower than one in each 7 million distinctive queries.

Whereas Barack Obama will not be Muslim, making AI Overviews’ response unsuitable, it drew its info from a chapter in a tutorial e-book titled Barack Hussein Obama: America’s First Muslim President? So not solely did the AI system miss the whole level of the essay, it interpreted it within the precise reverse of the meant means, says Mitchell. “There’s just a few issues right here for the AI; one is discovering supply that’s not a joke, however one other is decoding what the supply is saying accurately,” she provides. “That is one thing that AI techniques have hassle doing, and it’s essential to notice that even when it does get supply, it might probably nonetheless make errors.”
