AI hallucination cases fall for a second straight quarter, Charlotin database shows
New court decisions involving AI-hallucinated citations have fallen for a second consecutive quarter, according to researcher Damien Charlotin, who maintains a database of such cases. Writing on October 23, 2026, he attributed the decline to models that hallucinate less, legal tech verification tools, wider awareness and judicial standing orders, while cautioning that hallucination fatigue and underreporting may also play a part and that subtler AI errors may now matter more.
