SDXL 1.0 Now Commercially Licensed for Wide Usage

Anthropic has officially released Stable Diffusion model version 1.0 (SDXL 1.0) for commercial use under a license allowing wide usage across applications. This is great news for artists and creators looking to leverage AI image generation techniques in their work, as the high precision and detail available in SDXL 1.0 was previously restricted.

By making SDXL commercially available, Anthropic aims to empower creators to build their own artistic empires fueled by AI. The advanced capabilities of SDXL for handling diverse art styles with precision can accelerate creative workflows spanning photorealism, illustrations, concept art, and more.

Comparisons Show Community Prefers SDXL 1.0 Images

Anthropic shared some comparison statistics indicating the AI community prefers images generated by SDXL 1.0 over previous Stable Diffusion models such as 1.5. Specifically, 26.2% of evaluation participants favored SDXL 1.0 results as looking most realistic. However, these comparisons did not yet include benchmarking against other leading community-trained models. It remains to be seen through further testing if SDXL 1.0 will outperform the image quality and precision already achieved by top models like Anything V4 and Hypernetworks.

Model Handles Diverse Art Styles with Precision

Anthropic highlights SDXL 1.0 is optimized as an open domain model adept at handling virtually any art style while avoiding imparting its own stylistic bias onto generated images. This is critical for artists to maintain creative freedom and accurately translate the prompts and artistic direction they provide. Two example images showcase SDXL 1.0's capabilities for photorealism across different subjects. An image with high dynamic range between dark and bright areas depicts strong technical handling of light and shadows. Another image accurately renders a complex composition with foreground and background elements in and out of focus.

Examining Example Images from SDXL 1.0

Let's examine some of the example images Anthropic shared showing results from the new SDXL 1.0 model.

On the left, we see an example focused on exhibiting SDXL 1.0's high dynamic range capabilities between the dark muted tones of the background and bright vibrant light sources. Technical rendering of lighting and shadows is critical for photorealism and handled very well here. On the right, we have an image demonstrating accurate spatial separation between foreground and background subjects. The dock is sharply in focus up close, while the woman running on the stairs behind is softly blurred into the background.

Other Key Improvements in SDXL 1.0

Beyond improvements directly related to image generation quality, Anthropic notes SDXL 1.0 includes some other key upgrades making it easier to use:

First, SDXL 1.0 aims to better handle simple natural language prompts without needing complex phrasing or special keywords to output high quality images. This makes prompts faster to write and more closely match the actual desired end result.

Additionally, Anthropic says model training and fine-tuning should require less data wrangling to achieve better final precision. This accelerated workflow will empower more creators to develop custom AI models tailored to their unique needs and artistic style.

Using SDXL 1.0 Hands-On with Automatic1111

Thanks to the open release of SDXL 1.0, artists can immediately start using this powerful new model with the Automatic1111 GUI application for Stable Diffusion. Getting up and running takes just a few quick steps:

First, download the SDXL 1.0 model file along with the Refiner model into your Automatic1111 models folders. Next, make sure Automatic1111 is updated to v1.5.1 or higher for compatibility. Then in the application, select SDXL 1.0 as your model and make sure to have Skip CLIP enabled, disable unneeded extensions, and optionally add the SDXL Offset Lore in the Lore section.

After generating your base image with SDXL 1.0, you can further refine details and crispness by sending the image through Automatic1111's I2I processing using the SDXL Refiner model. Adjust noise reduction strength to balance detail enhancement vs unwanted artifacts. Consider toggling on Face Restoration to nicely improve facial features. And that's it! Now you're ready to start leveraging the new SDXL 1.0 capabilities.

Experimenting Further by Pushing Limits

Once comfortable with the basics, some advanced users may want to experiment even further and potentially push beyond recommended limits...

For example, although not officially supported, one could trial running the SDXL Refiner model directly for image generation at reduced resolution like 680x680. Then upscale to 1024x1024 for refinement. This risky shortcut actually yielded surprisingly good results in my tests! As always when creatively poking boundaries, your aesthetic mileage may vary.

Closing Thoughts on the New Possibilities with SDXL

With the open release of SDXL 1.0, artists now have an incredibly capable new tool at their fingertips to expand the boundaries of their creative potential.

It will be exciting to see over time if community trained models can eventually match or exceed the image precision already built into SDXL 1.0. But in the meantime, this model sets a new high quality bar for creators to start benefitting from today.

I can't wait to see the amazing original artworks, visual worlds, and creative visions people start bringing to life with SDXL 1.0! This feels like just the next chapter in the mass democratization of cutting edge AI technology to empower human imagination. The future is now - so let's start building it!


Q: Is SDXL 1.0 commercially licensed?
A: Yes, SDXL 1.0 is licensed for commercial use so you can freely use it to create and sell artwork.

Q: How does SDXL 1.0 compare to previous models?
A: Anthropic claims test users prefer images from SDXL 1.0 over previous Stable Diffusion models in side-by-side comparisons.

Q: What file types do I need to download?
A: You need to download the SDXL 1.0 base model, SDXL offset lora, and SDXL refiner model files.

Q: What Automatic1111 version is required?
A: You need to be running Automatic1111 v1.5.1 or higher for full SDXL 1.0 compatibility.

Q: Can I use SD 1.5 loras with SDXL 1.0?
A: No, you should use the dedicated SDXL offset lora instead of SD 1.5 loras.

Q: Why am I getting errors when using the refiner model?
A: Make sure to remove any lora from your prompt before using the SDXL refiner model to avoid errors.

Q: What resolution should I use?
A: 1024x1024 is the minimum, but you can experiment with higher sizes like 1280x1280.

Q: Should I use extensions like ControlNet?
A: It's best to turn them off when first testing SDXL 1.0 to avoid conflicts.

Q: How can SDXL 1.0 be used?
A: It is available in Automatic1111, on Anthropic's ClipDrop website, their DreamStudio platform, and more.

Q: Are there ways to use SDXL 1.0 beyond recommended methods?
A: Pushing limits by using the refiner model directly shows potential but may produce artifacts.
