How Stable is the Next Token? A Geometric View of LLM Prediction Stability

ICLR 2026poster

Large Language Models (LLMs) exhibit impressive capabilities yet suffer from sensitivity to slight input context variations, hampering reliability. Conventional metrics like accuracy and perplexity fail to assess local prediction robustness, as normalized output probabilities can obscure the underly…
