A new paper from arXiv investigates the ability of large language models, including GPT-5.4, to accurately verify legal citations. Researchers found that while models are adept at detecting when an entirely wrong case is cited, they struggle significantly with identifying citations that point to the correct case but do not support the proposition at the specific page referenced. This failure mode, termed "wrong-pinpoint corruptions," is particularly prevalent in court opinions and legal briefs, with even advanced models missing a substantial percentage of these errors. The study suggests that current models conflate topical relevance with page-level support, indicating a need for improved reasoning capabilities in legal AI applications. AI
