LLMs fabricate legal citations for Saudi law but not GDPR, study finds · 2 sources tracked

A new benchmark study reveals that large language models (LLMs) exhibit a significant disparity in their ability to accurately cite legal documents, particularly when dealing with different jurisdictions. While models like Gemini 2.5 Flash, GPT-OSS-120B, and Nemotron-3-Super-120B perform well on the EU's General Data Protection Regulation (GDPR), they frequently fabricate citations for the Saudi Personal Data Protection Law (PDPL). This fabrication occurs regardless of the query language (Arabic or English) and is often presented with high confidence, highlighting a critical need for verification safeguards before relying on LLMs for legal compliance.
