Omnimodal LLMs fail to act on detected sensory contradictions

Researchers have identified a "Representation-Action Gap" in omnimodal large language models, where models can internally recognize contradictions between textual claims and their sensory inputs but fail to reflect this in their outputs. A new benchmark, IMAVB, was created using movie clips to test this capability, revealing that current models often either accept false premises or reject too many standard claims. The study suggests the bottleneck for grounding in these models is in translating perception into action, rather than perception itself. AI

IMPACT Highlights a critical gap in omnimodal LLM grounding, suggesting current models struggle to translate perceived information into reliable actions.

    Senses Wide Shut: A Representation-Action Gap in Omnimodal LLMs

    When an omnimodal large language model accepts a question whose textual premise contradicts what it actually sees or hears, does the failure lie in perception or in action? Recent omnimodal models are positioned as perception-grounded agents that jointly process video, audio, and…
