In one of the latest legal filings containing incorrect information generated by artificial intelligence, the hallucination was not of the entirety of the supporting material, but apparently only the title.

In its explanatory brief ordered by the court, Latham & Watkins explained that the drafting attorney requested that Claude provide a full citation for an article supporting an expert declaration. Claude obliged, but apparently included a different title than that of the actual article. Latham further noted the citation was checked by a human team, but nobody noticed the incorrect title. No harm, no foul, they argued, since following the citation would get you to the article (with the correct title), and the material supported the declaration as intended.

Not much of a moral to this story—maybe be extra careful and check all elements of your citations?
