ByteDanceCreateImageAsset - ComfyUI Built-in Node Documentation

This node creates a personal image asset for ByteDance’s Seedance 2.0 service. It uploads an input image and registers it within a specified asset group. If no group ID is provided, it will initiate a real-person authentication process in your browser to create a new group before adding the asset.
