All these models are designed to be highly customizable and to run on hardware accessible to the average consumer. Additionally, they remain under the StabilityAI community license, which means they are available for general and non-commercial use for free.
The company admitted in a statement that the Stable Diffusion 3 Medium model, launched in June, “did not fully meet our standards or the expectations of our communities.” Therefore, StabilityAI decided to take its time to develop SD3.5 and advance in its mission to “transform visual media.”
One of the highlights of this new version is its ability to customize images with greater precision, allowing users to create more unique images. Additionally, the system has incorporated new stylistic options, such as photography or painting, and also accepts hashtags to adjust styles.

The company claims that the Stable Diffusion 3.5 Large model leads in terms of adherence to instructions and image quality, while Stable Diffusion 3.5 Large Turbo offers extremely fast inference times. Meanwhile, Stable Diffusion 3.5 Medium is the best option for those seeking a balance between performance and high visual quality.
Stable Diffusion 3.5 is free for non-commercial use, as well as for small and medium-sized businesses with revenues under one million dollars, but companies exceeding that amount will need to opt for an Enterprise license.
