Stable Diffusion Online - Free AI Image Generation FAQ
Can I use Stable Diffusion Online for free?+
Yes. Every new account receives a free credit balance for text-to-image and image-to-image runs.
Do I need to install anything?+
No. The playground runs server-side and streams results to your browser, requiring no local installation.
What is the difference between text-to-image and image-to-image?+
Text-to-image creates an image from a prompt alone, while image-to-image uses an existing image as a visual anchor and modifies it according to the prompt.
How does inpainting work?+
You mask a region of an image, provide a prompt, and Stable Diffusion fills the masked area while keeping the rest unchanged.
Do credits ever expire?+
Credits from one-time packs never expire; credits from monthly or yearly subscriptions refresh each period and do not roll over.
