The refiner refines the image making an existing image better. The SDXL base model performs significantly better than the previous variants, and the model combined with the refinement module achieves the best overall performance. You want to use Stable Diffusion, use image generative AI models for free, but you can't pay online services or you don't have a strong computer. 0 was released, there has been a point release for both of these models. Step 1: Update AUTOMATIC1111. The Base and Refiner Model are used sepera. If you use a LoRA with the base model you might want to skip the refiner because it will probably just degrade the result if it doesn't understand the concept. This checkpoint recommends a VAE, download and place it in the VAE folder. SDXL 0. But, newer fine-tuned SDXL base models are starting to approach SD1. I think we don't have to argue about Refiner, it only make the picture worse. 11:29 ComfyUI generated base and refiner images. -Img2Img SDXL. One has a harsh outline whereas the refined image does not. You will get images similar to the base model but with more fine details. 9vae. The refiner model adds finer details. You can use the base model. The SDXL base model performs. Number of rows: 1,632. Fixed FP16 VAE. Per the announcement, SDXL 1. SDXL uses base+refiner, the custom modes use no refiner since it's not specified if it's needed. Scheduler of the refiner has a big impact on the final result. Table of Content. Generating images with SDXL is now simpler and quicker, thanks to the SDXL refiner extension!In this video, we are walking through the installation and use o. SDXL uses base+refiner, the custom modes use no refiner since it's not specified if it's needed. The Base and Refiner Model are used sepera. 9 in ComfyUI, and it works well but one thing I found that was use of the Refiner is mandatory to produce decent images — if I generated images with the Base model alone, they generally looked quite bad. Custom nodes extension for ComfyUI, including a workflow to use SDXL 1. SDXL is made as 2 models (base + refiner), and it also has 3 text encoders (2 in base, 1 in refiner) able to work separately. 1. 0 composed of a 3.
