Flux ComfyUI Workflows

If you are looking at Flux comfyui workflows, the headline is that Flux is an open family from Black Forest Labs that spans both generation and editing, and most of it runs on your own hardware. The workflows on this page are the ready-made graphs for that: load a Flux checkpoint, give it a prompt or a reference image, and get a result, with the node graph already wired so you are not assembling it from scratch.

The family is wide, and picking the right variant matters. Flux.1 Schnell is the fast, Apache 2.0 model for rapid prototyping in a handful of steps. Flux.1 Dev is the higher-quality 12B model for finished work. Flux.1 Kontext does in-context editing from plain text instructions and keeps a character consistent across scenes, while Flux.1 Fill handles inpainting and outpainting. The newer Flux.2 line pushes further: Flux.2 Dev is a 32B model with up to 4MP output and multi-reference editing that blends several inputs, and Flux.2 Klein is the speed tier, with a 4B Apache 2.0 build that runs in around 8GB of VRAM.

What you reach for depends on the job. Generate a flux image from a written prompt, run flux image edit with a text instruction, outpaint a scene past its borders, or combine reference images into one coherent composition. Flux renders text in images more reliably than most open models, which is why it shows up in poster and graphic work as well as straight photo generation.

Everything here is open and editable. Open a Flux workflow on Comfy Cloud with nothing to install when you do not have the VRAM for the larger builds, or download the graph and run it locally for full control. Either way you choose the variant, tune the steps and guidance, and re-run until the result is right, with no watermark.
