FLUX 1.1 pro and FLUX.1 Tools arrive as native ComfyUI API nodes

ComfyUI's native API nodes let creators include hosted FLUX models in the same visual workflow as local processing steps. Black Forest Labs announced access to FLUX1.1 pro, its Ultra variant and FLUX.1 Tools. ComfyUI's launch explanation describes nodes that call paid model services, with users signing in and buying credits. The generation work for those nodes runs through the hosted service, which lets a workflow use models the creator is not running locally. The matched launch post explicitly describes chaining these APIs with open models.
