To stay competitive, media, advertising, and entertainment enterprises need to stay abreast of recent dramatic technological developments. Generative AI has emerged as a game-changer, offering unprecedented opportunities for creative professionals to push boundaries and unlock new realms of possibility. At the forefront of this revolution is Stability AI’s  family of cutting-edge text-to-image AI models. These models promise to transform the way we approach visual content creation, empowering large media, advertising, and entertainment organizations to tackle real-world business use cases with efficiency and creativity.

This technical post explores how these organizations can use the power of Stability AI to streamline workflows, enhance creative processes, and unleash a new era of advertising campaigning and visual storytelling.

Overview

Amazon Bedrock recently launched three new models by Stability AI: Stable Image Ultra, Stable Diffusion 3 Large, and Stable Image Core. These advanced models greatly improve performance in multisubject prompts, image quality, and typography and can be used to rapidly generate high-quality visuals for a wide range of use cases across marketing, advertising, media, entertainment, retail, and more. One of the key improvements of these models compared to Stable Diffusion XL (SDXL) (one of Stability AI’s older models) is text quality in generated images, with fewer errors in spelling and typography thanks to its innovative Diffusion Transformer architecture.

By learning the intricate relationships between visual and textual data, these models can generate highly detailed and coherent images from simple text prompts. The improved architecture combines the strengths of various deep learning techniques, including transformer encoders for text understanding, convolutional neural networks (CNNs) for efficient image processing, and attention mechanisms for capturing long-range dependencies and fine-grained details. The new family of models available on Amazon Bedrock are mentioned in the table below:

To evaluate the capabilities of these models, we tested a variety of prompts ranging from simple object descriptions to complex scene compositions. The experiments revealed that, although SDXL excelled at rendering common objects and scenes accurately, these newer models from Stability AI demonstrated improved performance on more nuanced and imaginative prompts. The new models better understand and visually express abstract concepts, stylized artistic renditions, and creative blends of disparate elements.

Stable Image Core is a newer, more affordable and faster version of SDXL. It’s based on the same diffusion architecture as SDXL. In comparison, Stable Diffusion 3 Large and Stable Image Ultra are based on the new diffusion transformer architectures, making them much better at typography.

Expanded training data of the SD3 base model—which is used for both Stable Diffusion 3 Large and Stable Image Ultra—has endowed it with stronger multimodal reasoning and world knowledge compared to SDXL. Some key improvements we observed from the prompt experimentation are the following:

1. Prompt adherence – These models excel at following complex and detailed prompts, particularly in surreal scenes, making sure that the generated images closely match the specified instructions. Stable Diffusion 3 Large and Stable Image Ultra work the best with natural language.
2. Text Rendering: Unlike SDXL, which may struggle with incorporating text into images, these newer models effectively generate and integrate text, enhancing the overall coherence of the visuals.
3. Complex Scene Handling: The new models demonstrate a improved ability to create intricate and detailed scenes, showcasing a better grasp of surreal elements as it understands them in your prompts.
4. Photorealism: The images produced by these models are more lifelike, with improved handling of textures, lighting, and shadows, making them visually striking.
5. Visual Aesthetics: The overall visual appeal is enhanced, making them more engaging and attractive.
6. Multimodal Capabilities: The new models can process various input types beyond just text, allowing for more context-aware image generation.
7. Scalability: The new architecture of these models supports handling larger datasets and generating higher-resolution images effectively.
8. Advanced Architecture: The SD3 base model (used for Stable Diffusion 3 Large and Stable Image Ultra) utilizes a new diffusion transformer combined with flow matching, which enhances its performance in generating high-quality images.

This approach allows for the creation of diverse, high-quality visuals that can be fine-tuned to help meet specific campaign requirements. Here are some posters generated by Stable Image Ultra:

Note:

The images generated could be different because your results depend on the parameters and their values, including the following:

1. The cfg_scale, which determines how strictly the diffusion process adheres to the prompt text
2. The height and width of the image in pixels
3. The number of diffusion steps to run
4. The random noise seed (which, if provided, makes the resulting generated image deterministic)
5. The sampler used for the diffusion process to denoise the generation
6. The array of text prompts used for generation
7. The weight assigned to each prompt

These parameters allow for fine-tuning and customization of the image generation process, resulting in diverse outputs based on their specific configuration.
