New research highlights significant challenges in maintaining contextual integrity within large language models (LLMs). A benchmark called CIMemories revealed that even advanced models like GPT-5 can exhibit up to 69% attribute-level violations, inappropriately leaking sensitive user information across tasks and repeated runs. Another study explored using reasoning and reinforcement learning to instill contextual integrity, showing substantial reductions in inappropriate disclosures while preserving task performance. These findings suggest that current LLMs lack the nuanced, context-dependent reasoning required for robust information control, indicating fundamental limitations beyond simple prompting or scaling.
