Stability AI has made significant strides in its open-source AI products with the release of Stable Diffusion 3.5, its latest image generation model. This new family includes three models designed for various use cases, offering users more customization, better performance, and faster processing times than previous versions.
The primary focus of these models is inclusivity. They are designed to generate images that are more representative and diverse, without the need for extensive prompting. This is a significant step forward in addressing past controversies where AI image generators displayed biases, making all users feel valued and considered.
A Trio of Powerful Models

The flagship model, Stable Diffusion 3.5 Large, is a powerhouse with almost 8 billion parameters and the ability to produce images at up to 1-megapixel resolutions. This makes it the most potent model in the Stable Diffusion lineup, a fact that is sure to impress and intrigue the audience.
Stability has also released the Large Turbo version for individuals needing faster outcomes. This model significantly decreases the time required to do jobs by producing photos faster at the expense of some image quality.
Lastly, the third model, Stable Diffusion 3.5 Medium, which is set to launch on October 29, is optimized for edge devices like laptops and smartphones. Also, it is expected to offer resolutions between 0.25 and 2 megapixels.
Enhanced Diversity and Flexibility

The most notable enhancement in the Stable Diffusion 3.5 series is its capacity to produce a wide range of output without extensive prompting. This diversity ensures a broader, more inclusive generation by including representations of individuals with different skin tones and features. Stability AI trained its models using a more flexible prompt system to accomplish this, allowing the captioning of each image with multiple prompt versions.
Additionally, the models include technical enhancements like Query-Key Normalization in transfer blocks, improving training stability, and streamlining fine-tuning procedures. However, when alternative seeds are utilized, image output changes even with similar prompts because of its flexibility.
Free for Non-Commercial Use

Like its previous versions, Stable Diffusion 3.5 is free for non-commercial use. While larger companies are required to obtain a license, companies with yearly revenues under $1 million can use the model for commercial purposes.
These powerful models are not just for the elite. They are widely accessible to developers and businesses on platforms like Hugging Face, GitHub, and Stability AI's API. This accessibility empowers our audience and opens up a world of possibilities, sparking excitement and anticipation.
