LLMs struggle with dispersed facts and safety prompts in long-context tasks

A new arXiv paper investigates how Large Language Models (LLMs) with large context windows handle information distribution and anti-hallucination prompts. The study, which tested Gemini 2.5-Flash, ChatGPT-5-mini, Claude 4.5 Haiku, and Deepseek-v3.2-chat, found that models struggle with dispersed facts and that safety prompts can lead to over-conservative refusals. These issues suggest that models often fail due to ineffective context utilization, highlighting a need for improved robustness in long-horizon agentic workflows. AI

IMPACT Highlights challenges in LLM context utilization and safety prompting, suggesting areas for future model development.
