Federal judge chooses not to sanction lawyer who admitted using AI in mistake-filled brief

The filing in question was related to a case in which Guyer's client Karen Iovino claimed she faced retaliation from employer Michael Stapleton Associates, and "was fired for reporting alleged issues about MSA's contract with the State Department to that agency's Office of Inspector General." In an August filing, Guyer denied citing "'fictitious' cases," and said that the cases did in fact exist, but that they were misquoted and miscited by generative AI. "GPTs generate excellent to brilliant legal arguments," Guyer wrote in a separate declaration, saying that the errors were generated by Atrophic Inc.'s Claude 3 Opus, which is one of several AI tools Guyer says he uses. "I utilize a suite of generative AI technologies for legal research and writing purposes, and GPT legal document briefing," Guyer said.
