SDXL 0.9 is designed to run efficiently on consumer hardware, making it accessible to a wide range of users.


What is SDXL 0.9?

SDXL 0.9 is a pivotal version in the evolution of Stability AI’s Stable Diffusion models, a suite of text-to-image generative AI technologies. As a precursor to the more advanced Stable Diffusion 3.5, SDXL 0.9 set the stage for significant improvements in performance and feature set. This model leverages the power of generative AI to transform text prompts into highly detailed and realistic images, pushing the boundaries of what AI-generated art can achieve.


A Step Forward for Stability AI with Stable Diffusion


Building on the success of the beta release of Stable Diffusion XL in April, SDXL 0.9 introduces a host of improvements in image quality and composition. Stability AI offers an enterprise license for larger deployments, making the model suitable for organizations with greater resource needs. This advancement allows creators to generate hyper-realistic visuals for various applications such as films, television, music, instructional videos, design, and industrial use. By pushing the boundaries of generative AI imagery, SDXL 0.9 is one of the most powerful models available, capable of generating images that meet the highest quality standards, and emerges as a frontrunner in real-world applications for AI-generated visuals.

Key Features and Improvements

SDXL 0.9 brings a host of enhancements over its predecessors, making it a robust tool for artists, designers, and creative professionals. Here are some of the standout features:


  • Improved Image Quality: SDXL 0.9 excels in producing high-quality images with intricate textures and lifelike colors, elevating the visual fidelity of AI-generated art.

  • Enhanced Stability: Designed to be more stable and less prone to errors, this model ensures a smoother and more reliable user experience.

  • Increased Customization Options: Users can fine-tune the model to suit specific needs, adjust the output quality, and select from multiple variants, making SDXL 0.9 highly customizable for diverse applications.


These improvements make SDXL 0.9 a powerful model for generating images that meet the highest quality standards, whether for artistic projects or commercial use.


Image to Image Functionality Enhancing Image Quality

One of the standout features of the SDXL series is its versatility, offering functionalities that extend beyond basic text prompting. For instance, the suite enables image-to-image prompting, allowing users to input one image and obtain variations of that image. Additionally, SDXL facilitates inpainting, which involves reconstructing missing parts of an image, and outpainting, which seamlessly extends existing images.

SDXL 0.9 and Stable Diffusion 3.5 Pushing the Boundaries

The driving force behind the compositional advancements in Stability AI’s SDXL 0.9 lies in its substantially increased parameter count. Parameters refer to the weights and biases within the neural network that the model is trained on. SDXL 0.9 boasts one of the largest parameter counts among open models, with a base model of 3.5 billion parameters and a model ensemble pipeline consisting of 6.6 billion parameters. The ensemble pipeline aggregates the results of running the input through two models, with the second stage model adding finer details to the output generated by the first stage.


In comparison, the beta version of SDXL runs on 3.1 billion parameters and utilizes a single model. The notable increase in parameter count empowers SDXL 0.9 to produce imagery with enhanced depth and higher resolution. The model’s processing power is further augmented by running on two CLIP models, including OpenCLIP ViT-G/14, which is one of the largest OpenCLIP models trained to date. With a resolution of 1024x1024, SDXL 0.9 pushes the boundaries of visual fidelity.


The use of open models contributes to the flexibility and customization options available in SDXL 0.9.

Safety and Integrity

Stability AI has prioritized safety and integrity in the design of SDXL 0.9. The model is trained on an extensive dataset of images and text prompts, ensuring that its outputs are both respectful and appropriate. Key safety features include:


  • Content Filtering: SDXL 0.9 is equipped with mechanisms to filter out inappropriate or offensive content, ensuring that the generated images are safe and respectful.

  • Bias Mitigation: The model incorporates strategies to mitigate bias, striving to produce fair and unbiased outputs.

  • Transparency: With a focus on transparency, SDXL 0.9 provides clear explanations of how outputs are generated and the data used for training, fostering trust and understanding among users.


Overall, SDXL 0.9 stands out as a reliable and versatile text-to-image model, offering a blend of advanced features and a strong commitment to ethical AI practices. Whether for artistic endeavors or commercial applications, SDXL 0.9 provides a robust platform for creating high-quality, safe, and customizable AI-generated imagery.


What to Look Forward To: Community License

To delve deeper into the specifications and testing of this revolutionary model, the Stability AI SDXL team plans to release a research blog in the near future. This resource will provide comprehensive insights into the workings of SDXL 0.9, offering a valuable resource for researchers, developers, and AI enthusiasts. Ensuring integrity and safety measures at the early stages of development is crucial for responsible deployment.

Highlights of SDXL’s capabilities include:


  • Next-level photorealism capabilities

  • Enhanced image composition and face generation

  • Rich visuals and jaw-dropping aesthetics

  • Use of shorter prompts to create descriptive imagery

  • Greater capability to produce legible text


As SDXL 0.9 ushers in a new era of AI-generated imagery, Stability AI is actively working on making the model accessible to users. The model can already be accessed via ClipDrop, while the API is expected to be made available shortly. Furthermore, an open release is scheduled for mid-July, marking the transition to SDXL 1.0 and ensuring wider availability for users to leverage the creative potential of this state-of-the-art AI technology. The Stability AI Community License allows for both commercial and non-commercial use, particularly for users with annual revenues under $1 million.


With its remarkable advancements in composition, parameter count, and processing power, SDXL 0.9 from Stability AI has established itself as a game-changer in the field of generative AI imagery. This breakthrough has opened up a myriad of possibilities for various industries, empowering creators to bring their imaginative ideas to life with unparalleled realism and detail.
