Modality Collapse as Mismatched Decoding: Information-Theoretic Limits of Multimodal LLMs

"Multimodal LLMs can process speech and images, but they cannot hear a speaker's voice or see an object's texture. We show this is not a failure of encoding: speaker identity, emotion, and visual attributes survive through every LLM layer (3--55$\times$ above chance in linear probes), yet removing 64..."
