MLLM-Microscope: Unlocking Hidden Structure Within Multimodal Large Language Models

Researchers introduce MLLM-Microscope, a novel analytical system that examines the internal representations of multimodal large language models (MLLMs) by measuring linearity, intrinsic dimension, and anisotropy across transformer layers. Testing on LLaVA-NeXT and OmniFusion reveals that modality fusion approaches significantly influence how embeddings behave within the model architecture, with OmniFusion demonstrating more consistent dimensional properties across layers.

Acoustic and perceptual differences between standard and accented speech and their voice clones

Researchers analyzed how voice cloning technology preserves accented speech compared to standard speech, finding that clones of accented speakers show larger perceptual differences from originals despite similar baseline-normalized embedding distances. The study reveals that accent variation significantly impacts perceived speaker identity and intelligibility in voice cloning systems, suggesting current speaker-discriminative embeddings don't fully capture accent preservation.

Evaluating LLM Alignment With Human Trust Models

Researchers analyzed how the GPT-J-6B language model internally represents and reasons about trust by comparing its embeddings to established human trust models. The study found that the AI's trust representation most closely aligns with the Castelfranchi socio-cognitive model, suggesting LLMs encode social concepts in meaningful ways.
