arXiv:2606.24077v1 Announce Type: new Abstract: Contextual entrainment, which is a newly discovered phenomenon in large language models (LLMs), refers to the tendency of a model to assign higher probabilities to tokens that appear in its context. In this work, we extend this phenomenon from the token level to the sentence level by examining the per-token mean log-probability of a sentence instead of the probabilities of individual tokens. We investigate sentence-level contextual entrainment across 26 LLMs from seven families and two datasets, which cover both subjective and objective tasks. We
The proliferation of various large language models and continued academic interest in their fundamental mechanisms facilitate deeper analysis of newly observed phenomena like contextual entrainment.
Understanding contextual entrainment at a sentence level provides crucial insights into how LLMs process and generate coherent text, impacting their reliability and the development of future AI applications.
This research refines our understanding of LLM predictability and how context influences output, moving beyond token-level analysis to a more complex sentence-level assessment of language generation.

Improved debugging and fine-tuning methods for LLMs will emerge, leading to more robust and less 'hallucinating' models.
This deeper understanding could enable the development of more sophisticated AI agents that can maintain conversational coherence over longer interactions.
Enhanced control over contextual influences might open new avenues for personalized content generation and adaptable AI assistants in complex, domain-specific tasks.
