ChatGPT caselaw will cost you

ST. LOUIS — An appeals court in Missouri lambasted a pro se litigant for submitting multiple “fictitious cases” conjured up by the A.I. chat bot ChatGPT, which offered citations “that have potentially real case names — presumably the result of algorithmic serendipity,” that pointed to either non-existent rulings or to irrelevant ones. The litigant must pay $10,000 to opposing counsel for wasting their time with the “frivolous appeal.”
