CICM exposes stale binding in LLMs

UC Berkeley researchers introduce CICM, a benchmark showing that LLMs can retain updated facts yet answer with outdated values because attention selects stale mentions. The paper proposes training-free attention redirection that corrects most tested errors.

// ANALYSIS

This reframes context failure as a selection problem, not simply a memory or context-window problem.

  • –Probes recover the current value in hidden states even when models output an old one.
  • –Nearby repetitions of obsolete values can overpower newer assignments through attention drift.
  • –CICM spans preference dialogues, changing constraints, and operational agent histories.
  • –Attention interventions improve answers across Qwen, Llama, Mistral, and Gemma without retraining.
  • –The results suggest agent systems need explicit state-selection safeguards, not just larger context windows.
