Multimodal Language Models See Better When They Look Shallower
Which visual encoder layer should a multimodal language model actually use?
Later is not always better. Shallower visual layers can preserve information that deeper layers discard.

Multi-Layer Visual Feature Fusion in Multimodal LLMs
How should complementary visual features from different layers be combined?
Fusion works best when its location and mechanism match the information each visual layer contributes.

To Preserve or To Compress
Should the connector preserve visual tokens or compress them before they reach the language model?
Connector structure is an information bottleneck, not a minor implementation detail.
