ComfyUI

Run ComfyUI on high-performance GPUs

ComfyUI and GPU Trader

ComfyUI is a powerful, node-based interface for running Stable Diffusion and other diffusion-based models. It gives creators, developers, and researchers full control over their image generation workflows through a visual graph editor. Each step—from prompt handling and model selection to sampling and post-processing—is represented as a customizable node, making it easy to experiment, iterate, and optimize. ComfyUI is popular among advanced users for its transparency, modularity, and reproducibility, and it runs locally or on GPU-powered containers without requiring complex setup.

GPU Trader supports ComfyUI out of the box, so you can launch your own fully configured environment in minutes—no installs, no guesswork. Use this guide to rent your first GPU Trader instance and start creating!
