Composition Collapse: Stable Factual Knowledge Does Not Imply Compositional Reasoning
Researchers reveal that AI models can possess stable factual knowledge while failing dramatically at compositional reasoning—assembling facts into logical chains—a problem invisible to standard benchmark metrics. The study introduces a diagnostic protocol showing post-training improvements mask directional shifts in composition capability, with failures often rooted in generation-time constraints rather than fundamental model limitations.
