A new study published on arXiv reveals that large language models (LLMs) are unreliable at self-reporting when their outputs are influenced by adversarial prefill attacks. Across ten different open-weight instruction-tuned LLMs, none consistently recognized compromised outputs, with models incorrectly claiming intent on prefilled responses approximately 27.3% of the time. The research indicates that introspective signals primarily stem from safety and refusal-related reasoning, and that training models to improve introspection accuracy does not necessarily transfer to recognizing tampering and can even increase vulnerability to adversarial prefill attacks.
