Researchers have developed a new framework called Analysis-by-Proxy to investigate the localization accuracy of Vision-Language Models (VLMs) when used as condition encoders in image editing pipelines. The study found that VLMs, despite their strong standalone localization capabilities, struggle to maintain this accuracy in complex scenes when restricted to a single forward pass as a condition encoder. The Analysis-by-Proxy method trains a lightweight model on intermediate VLM representations to uncover how localization information is encoded and extracted, revealing a mismatch between VLM representations and current editing pipeline extraction strategies.
