Holkenborg takes a tour of his sampling set up, demonstrates some of his gear and talks about how he has used it in his work. Currently, it works well at fixing 21:9 double characters** and adding fog/edge/blur to everything. 10. ), and then the Diffusion-based upscalers, in order of sophistication. You’ll notice in the sampler list that there is both “ Euler ” and “ Euler A ”, and it’s important to know that these behave very differently! The “A” stands for “Ancestral”, and there are several other “Ancestral” samplers in the list of choices. Stable Diffusion XL (SDXL) is a powerful text-to-image generation model that iterates on the previous Stable Diffusion models in three key ways: the UNet is 3x larger and SDXL combines a second text encoder (OpenCLIP ViT-bigG/14) with the original text encoder to significantly increase the number of parameters. 0 base checkpoint; SDXL 1. While it seems like an annoyance and/or headache, the reality is this was a standing problem that was causing the Karras samplers to have deviated in behavior from other implementations like Diffusers, Invoke, and any others that had followed the correct vanilla values. The beta version of Stability AI’s latest model, SDXL, is now available for preview (Stable Diffusion XL Beta).

If you want something fast (aka, not LDSR) for general photorealistic images, I'd recommend 4x. 0 with both the base and refiner checkpoints. Even the Comfy workflows aren’t necessarily ideal, but they’re at least closer. I will focus on SD. You may want to avoid any ancestral samplers (The ones with an a) because their images are unstable even at large sampling steps. When focusing solely on the base model, which operates on a txt2img pipeline, for 30 steps, the time taken is 3. I figure from the related PR that you have to use --no-half-vae (would be nice to mention this in the changelog!). then using prediffusion. To see the great variety of images SDXL is capable of, check out Civitai collection of selected entries from the SDXL image contest. As the power of music software rapidly advanced throughout the ‘00s and ‘10s, hardware samplers began to fall out of fashion as producers favoured the flexibility of the DAW.

There are 18 high quality and very interesting style Loras that you can use for personal or commercial use. ago. 7 seconds. It has many extra nodes in order to show comparisons in outputs of different workflows. This repository contains a handful of SDXL workflows I use, make sure to check the usefull links as some of these models, and/or plugins are required to use these in ComfyUI. The refiner is trained specifically to do the last 20% of the timesteps so the idea was to not waste time by. The total number of parameters of the SDXL model is 6. All images below are generated with SDXL 0. Compose your prompt, add LoRAs and set them to ~0. SDXL also exaggerates styles more than SD15. It will serve as a good base for future anime character and styles loras or for better base models. SDXL 1. the prompt presets. 0. For one integrated with stable diffusion I'd check out this fork of stable that has the files txt2img_k and img2img_k. You also need to specify the keywords in the prompt or the LoRa will not be used. 16. anyone have any current/new comparison sampler method charts that include DPM++ SDE Karras and/or know whats the next best sampler that converges and ends up looking as close as possible to that? EDIT: I will try to clarify a bit, the batch "size" is whats messed up (making images in parallel, how many cookies on one cookie tray), the batch. Googled around, didn't seem to even find anyone asking, much less answering, this. To simplify the workflow set up a base generation and refiner refinement using two Checkpoint Loaders. but the real question is if it also looks best at a different amount of steps. 9 brings marked improvements in image quality and composition detail. Place VAEs in the folder ComfyUI/models/vae. There are two. And then, select CheckpointLoaderSimple. g. Overall, there are 3 broad categories of samplers: Ancestral (those with an "a" in their name), non. Graph is at the end of the slideshow. 5 is actually more appealing. So I created this small test.
