About

Content & Construction: CICM is a comprehensive benchmark designed to test whether Large Language Models (LLMs) use the current state when earlier versions remain in context. It features programmatic ground truth, explicit update rules, and synthetic overwrite tasks alongside complex operational logs like warehouse operations.

Scoring & Findings: The benchmark classifies answers as 'current', 'old' (stale binding), or other variables to diagnose selection failures. Key findings include the phenomenon of 'attention drift,' where models favor old values over current ones, and a training-free intervention method that redirects attention to correct these errors.
