SDXL
SDXL (Stable Diffusion XL) is a large-scale text-to-image generation model released by Stability AI and an upgraded version of the Stable Diffusion series. It employs a dual text-encoder architecture with a substantially larger parameter count, enabling the generation of higher-resolution images with richer detail. The model also demonstrates stronger semantic understanding of complex prompts and is widely used in AI art creation and design assistance applications.
Timeline (last 90 days)
In the autonomous art direction agent built by the developer, the planner generates shot descriptions, SDXL (Juggernaut XL v9) renders images, a vision model evaluates the output and writes correction instructions, and the loop reruns until the critic model passes it.
Stable Diffusion 1.5 has about 0.9B parameters, SDXL about 2.6B, and Flux.1-dev 12B.
In ComfyUI, running SDXL alone to generate one image takes about 15 to 30 seconds.
By default, after generating one image, the SDXL checkpoint, CLIP text encoder, and VAE remain resident in VRAM, occupying about 8GB; after calling /free, VRAM falls back to a baseline of about 2.2GB.
SDXL generating a 1024×1024 image occupies approximately 6–8 GB of VRAM.
An Ollama 14b model combined with SDXL 1024×1024 generation requires approximately 14.5 GB of VRAM, which is tight but barely feasible on a 16 GB card.
The SDXL base model alone occupies approximately 6–7 GB of VRAM, and peak VRAM can easily exceed 20 GB when simultaneously loading the Refiner, multiple ControlNet weights (approximately 1.4 GB each), and a high-precision VAE.
SD XL introduced a dual-encoder architecture (CLIP ViT-L + OpenCLIP ViT-bigG), improving semantic capture for long prompts.
According to the publisher's description, Nanosaur 2 outperforms the SDXL model in many comparisons, despite having far fewer parameters than SDXL.
The score gaps between subsequent models such as Flux and SDXL on public benchmarks have already become quite limited.
