Attention-Path Fragility as an Uncertainty Signal in Large Language Models

- What happened
- Researchers propose ASMI, a method to detect when language models are uncertain by measuring how fragile their attention pathways are to perturbation.
- Why it matters
- Matters for engineers building systems where catching model errors matters, especially in grounded question-answering where context drives answers.
- Watch out
- Method works well for context-dependent tasks but fails for knowledge recall from model weights, limiting applicability across all LLM use cases.
