A new research paper explores the deterministic, task-free fixed-point structure of language models, revealing that prompt-model interactions significantly influence this structure. The study found that even short prompts can alter a model's structural class and reorder model performance, while instruction tuning had a negligible effect. Proposed mechanistic explanations, such as prefix length and attention-sink dominance, were found to be insufficient, indicating that the prompt-model pair is the fundamental unit of explanation for these observed phenomena.
