A user on Reddit has developed a custom node for ComfyUI, a popular Stable Diffusion interface, to improve the quality of the Ref2VA model. The user found that Ref2VA produced lower quality results than the similar fl2va model, despite sharing the same architecture. By selectively overlaying specific tensor blocks from Ref2VA onto an fl2va base model, the new node aims to preserve or enhance fl2va's quality while retaining Ref2VA's reference capabilities. The developer recommends using blocks 30-49 from Ref2VA and advises against using earlier blocks, which were found to degrade quality. AI
