The method combines vision-encoder features from multiple layers, using the text instruction to weight layer groups before sending fused features to the language model. This changes information carried by each visual token without increasing token count, though the aggregator adds computation. On LLaVA-v1.5-7B, it scores 1519.8 on MME-p versus 1480.6 for baseline and leads on eight of ten benchmarks.
