Gemma-3-27B shows fragile reality monitoring in vision-language models

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new method to test the reality monitoring capabilities of vision-language models (VLMs), specifically their ability to distinguish between internally generated concepts and actual image content. The study found that among six tested VLMs, only Gemma-3-27B could reliably identify injected concepts, though its source attribution was fragile. This failure mode was also observed in ordinary captioning, where injected objects appeared in a significant percentage of captions for real photographs, highlighting the need to evaluate both content and reported source in multimodal self-reports. AI

IMPACT Highlights a critical limitation in current vision-language models regarding distinguishing internal thoughts from external stimuli, impacting their reliability in real-world applications.

    Did I See It or Think It? Probing Reality Monitoring in Vision-Language Models with Concept Injection

    arXiv:2611.09014v1 Announce Type: new Abstract: Recent work tests whether language models can introspect by injecting a concept direction into their activations and asking whether they notice it and can name it. These studies are text-only. Vision-language models (VLMs) face an a…
