The outlet has issued dozens of corrections to A.I.-generated news summaries since it started using the technology to write them this year.

Bloomberg, the financial news powerhouse, has been experimenting with using artificial intelligence to help produce its journalism.
It hasn’t always gone smoothly.
The news outlet has had to correct at least three dozen A.I.-generated summaries of articles published this year. One happened on Wednesday, when Bloomberg broke news about President Trump’s auto tariffs.
The article correctly reported that Mr. Trump would announce the tariffs as soon as that day. But the bullet-point summary of the article written by A.I. inaccurately said when a broader tariff action would take place.
Bloomberg is not alone in trying A.I. — many news outlets are figuring out how best to embrace the new technology and use it in their reporting and editing. The newspaper chain Gannett uses similar A.I.-generated summaries on its articles, and The Washington Post has a tool called “Ask the Post” that generates answers to questions from published Post articles.
And problems have popped up elsewhere. Earlier this month, The Los Angeles Times removed its A.I. tool from an opinion article after the technology described the Ku Klux Klan as something other than a racist organization.
Bloomberg News said in a statement that it publishes thousands of articles each day, and “currently 99 percent of A.I. summaries meet our editorial standards.”
