A new research paper introduces a "channel-transition" framework to explain why large language models struggle to maintain context and instructions over extended multi-turn conversations. The study proposes the Goal Accessibility Ratio (GAR) as a metric to quantify the degradation of attention to key instructions. Researchers found that while attention to instructions may close, relevant information can persist in residual representations, leading to varied failure modes across different model architectures.
