arXiv:2606.03871v1 Announce Type: cross Abstract: Visual instruction tuning effectively adapts a pre-trained Large Language Model (LLM) to process image information alongside text. Yet, it remains unclear how visual features are embedded into the layer-wise hierarchy of abstractions of the LLM backbone. Across a diverse set of vision-language architectures, we show that instruction tuning primarily serves as a bridge, embedding visual features directly into the intermediate semantic layers of the LLM, bypassing the early layers devoted to unimodal processing. With probing analyses and causal i
The rapid development and integration of multimodal AI necessitate understanding how different data types converge within large language models.
This research provides critical insight into the architectural mechanics of visual-language integration, which is fundamental for advancing multimodal AI capabilities.
Our understanding of how visual information is processed within LLMs shifts, suggesting a more direct embedding into semantic layers rather than early unimodal processing stages.
