4. Customizability: The model is designed to be highly customizable, allowing for fine-tuning and integration into various workflows.

5. Efficiency: Optimized to run on standard consumer hardware, making it accessible to a wider range of users.

The Technical Leap

Stable Diffusion 3.5 builds upon its predecessor with two major architectural changes:

1. QK Normalization: This technique, borrowed from Google's research, helps stabilize the model training process.

2. Double Attention Layers: An enhancement that likely contributes to the model's improved performance and output quality.

These technical improvements result in a more robust and capable model, addressing some of the criticisms faced by its predecessor, Stable Diffusion 3 Medium.

Model Variants and Performance

Stability AI has released two main variants of the model:

1. Stable Diffusion 3.5 Large: An eight-billion-parameter model capable of generating professional-quality images at 1-megapixel resolution.

2. Stable Diffusion 3.5 Large Turbo: A distilled version optimized for speed, requiring only four steps for image generation.

Both variants excel in prompt adherence and image quality, with Stable Diffusion 3.5 Large leading the market in these aspects.

Accessibility and Hardware Requirements

One of the key focuses of Stable Diffusion 3.5 is its accessibility:

• Consumer Hardware Compatibility: The models are optimized to run on standard consumer GPUs, making high-quality AI image generation more accessible.

• Stable Diffusion 3.5 Medium: Coming soon, this 2.5-billion-parameter model is specifically designed for consumer hardware, further democratizing AI image generation.

Licensing and Availability

Stability AI has adopted a permissive licensing model for Stable Diffusion 3.5:

• Free for Non-Commercial Use: Individuals and organizations can use the model at no cost for non-commercial purposes, including scientific research.
