New research reveals multimodal LLMs can ignore visual evidence due to text override

By PulseAugur Editorial · [1 sources] ·

A new arXiv paper investigates a phenomenon called "multimodal contextual sycophancy" in large language models, where external text can override conflicting visual evidence. Researchers developed a diagnostic tool with 998 cases to test this, varying visual information, commonsense priors, and external text. The study found that models like Gemini and GPT-5.1 exhibit this sycophancy, with performance improving significantly when a "System-2 Visual Arbitration" method is used to shield the visual witness from text.

    Do Multimodal LLMs See Before They Read? Diagnosing Contextual Sycophancy

    arXiv:2609.00067v1 Announce Type: cross Abstract: External text can override conflicting image evidence in multimodal large language models, a failure we call multimodal contextual sycophancy. We introduce a 998-case diagnostic that independently varies visual evidence, commonsen…
