But that's a stupid comparison when it's obvious from how much better the sdxl base is over 1. Even the Comfy workflows aren’t necessarily ideal, but they’re at least closer. Note: I used a 4x upscaling model which produces a 2048x2048, using a 2x model should get better times, probably with the same effect. 0. 9 in ComfyUI, with both the base and refiner models together to achieve a magnificent quality of image generation. Refine image quality. I've been using the scripts here to fine tune the base SDXL model for subject driven generation to good effect. This is why we also expose a CLI argument namely --pretrained_vae_model_name_or_path that lets you specify the location of a better VAE (such as this one). WARNING - DO NOT USE SDXL REFINER WITH DYNAVISION XL. 5 models in terms of the fine detail they can generate. To make full use of SDXL, you'll need to load in both models, run the base model starting from an empty latent image, and then run the refiner on the base model's output to improve detail. It achieves impressive results in both performance and efficiency. 1 in terms of image quality and resolution, and with further optimizations and time, this might change in the near. 9 base vs. md.

SD+XL workflows are variants that can use previous generations. And this is the only 'like for like' fair test. Scheduler of the refiner has a big impact on the final result. a closeup photograph of a. Yeah I feel like the refiner is pretty biased and depending on the style I was after it would sometimes ruin an image altogether. 0-base. collect and CUDA cache purge after creating refiner. The SDXL base model performs significantly better than the previous variants, and the model combined with the refinement module achieves the best overall performance. But these improvements do come at a cost; SDXL 1. 5 or 2. So the "Win rate" (with refiner) increased from 24. In this case, there is a base SDXL model and an optional "refiner" model that can run after the initial generation to make images look better. Comparing 1. A new architecture with 2. The abstract from the paper is: We present SDXL, a latent diffusion model for text-to-image synthesis. TIP: Try just the SDXL refiner model version for smaller resolutions (f. 0 they reupload it several hours after it released. The last step I took was to use torch. Step Zero: Acquire the SDXL Models. It is currently recommended to use a Fixed FP16 VAE rather than the ones built into the SD-XL base and refiner for. Part 4 - we intend to add Controlnets, upscaling, LORAs, and other custom additions. But after getting comfy, have to say that comfy is much better for sdxl with the ability to use both base and refiner together. The one where you start the gen in SDXL base and finish in refiner using 2 different sets of CLIP nodes. 0 VAE, but when I select it in the dropdown menu, it doesn't make any difference (compared to setting the VAE to "None"): images are exactly the same. I created this comfyUI workflow to use the new SDXL Refiner with old models: Basically it just creates a 512x512 as usual, then upscales it, then feeds it to the refiner. Sélectionnez le modèle de base SDXL 1. Introduce a new parameter, first_inference_step : This optional parameter, defaulting to None for backward compatibility, is intended for the SDXL Img2Img pipeline. 0-mid; We also encourage you to train custom ControlNets; we provide a training script for this. 6B parameter refiner, creating a robust mixture-of. When you click the generate button the base model will generate an image based on your prompt, and then that image will automatically be sent to the refiner. co SD-XL 1.
