ComfyUI Kontext Duo Image Analyzer

By yamanacnView on GitHub →

This is a custom node designed for ComfyUI that leverages the multimodal large model Doubao from Volcengine Ark to intelligently compare two input images. You can provide two images and a custom text prompt. The node will send this information to the large model and return a detailed textual description of the similarities and differences between the two images.
