When calling the gRPC API, prompt is the only required variable. 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. I did comparative renders of all samplers from 10-100 samples on a fixed seed (1. You can construct an image generation workflow by chaining different blocks (called nodes) together. NOTE: I've tested on my newer card (12gb vram 3x series) & it works perfectly.

Two Samplers (base and refiner), and two Save Image Nodes (one for base and one for refiner). Use a noisy image to get the best out of the refiner. 5’s 512×512 and SD 2. discoDSP Bliss. 9 the refiner worked better I did a ratio test to find the best base/refiner ratio to use on a 30 step run, the first value in the grid is the amount of steps out of 30 on the base model and the second image is the comparison between a 4:1 ratio (24 steps out of 30) and 30 steps just on the base model. It tends to produce the best results when you want to generate a completely new object in a scene. Create an SDXL generation post; Transform an. SDXL, after finishing the base training, has been extensively finetuned and improved via RLHF to the point that it simply makes no sense to call it a base model for any meaning except "the first publicly released of it's architecture. 5, I tested exhaustively samplers to figure out which sampler to use for SDXL. Also, if it were me, I would have ordered the upscalers as Legacy (Lanczos, Bicubic), GANs (ESRGAN, etc. 9 base model these sampler give a strange fine grain texture.
