What is Stable Diffusion 3.5 Large?
Stable Diffusion 3.5 Large is Stability AI’s text-to-image model based on a Multimodal Diffusion Transformer. It supports a range of visual styles and prompts that describe objects, composition and text within an image.
This official demo includes a negative prompt, seed, width, height, guidance and step controls. Its defaults are 1024 × 1024 pixels, 40 steps and guidance 4.5. These are demo defaults, not a requirement for every prompt.
Use the main prompt for the desired scene and the negative prompt for unwanted features. This page embeds the Large model, not Large Turbo or Medium. The model is distributed under the Stability Community License.

Stable Diffusion 3.5 Large FAQ
Inputs, generation settings, account requirements and troubleshooting.
Is Stable Diffusion 3.5 Large free to use here?
The public demo can be used within its Hugging Face GPU allowance. Free use is limited by the hosting provider’s quotas and shared capacity; it is not unlimited. Image Toolkit does not sell credits for this embedded tool.
What is the negative prompt for?
It describes elements or visual artifacts you want to discourage. It is separate from the main prompt, which describes the image you do want.
Is this Stable Diffusion 3.5 Large Turbo?
No. This is the original Large model. Large Turbo and Medium are separate checkpoints with different inference characteristics.
Can I upload an image in this demo?
This official interface generates from text and does not include an image upload for editing. Choose an image editor from the directory for reference-based changes.
Do I need an account or API key for Stable Diffusion 3.5 Large?

Why is Stable Diffusion 3.5 Large not loading or generating?
The Space may be starting, busy or temporarily unavailable, or your GPU allowance may be exhausted. Check the message inside the tool. Select Reload if the frame is blank; wait for the provider’s quota reset if your allowance has run out.
