arXiv:2606.16011v1 Announce Type: new Abstract: Standard accuracy benchmarks are designed to test how closely large language models (LLMs) approach correct answers, but are not suitable for testing whether LLMs stick with a correct answer when that answer is challenged by a plausible counter-argument. We introduce a controlled protocol for evaluating answer stability: after a model answers a multiple-choice question correctly, we challenge the model's answer with a coherent argument for an incorrect option and measure whether the model flips. The setup a) isolates argumentative content from ov
The proliferation of advanced LLMs necessitates robust evaluation beyond simple accuracy, especially as these models are deployed in sensitive applications.
Understanding LLM 'answer instability' when challenged reveals critical vulnerabilities in their reasoning and robustness, impacting trust and deployability.
Traditional benchmark metrics alone are insufficient; new evaluation protocols are required to assess LLM reliability against sophisticated counterarguments.
