In this video, I'll show you how to use NVIDIA's new Pixel ID model to upscale images all the way to 4K with impressive detail and texture, even on low VRAM GPUs.

You'll learn how to install the required models, set up the original NVIDIA workflow in ComfyUI, and use my workflow that combines Pixel ID, Qwen Image Edit 2511, and Flux Klein to achieve significantly better results, especially for very small and old images.

We'll compare the original NVIDIA workflow against my workflow, test real photos, old photographs, and anime images, and see how each model contributes to the final result.
