Stable Diffusion: Can I use Stable Diffusion commercially for free?

Yes, if your organization has less than $1M annual revenue. Organizations exceeding $1M annually must obtain an Enterprise License from Stability AI.

Source
Stable Diffusion: What are Stable Diffusion's image resolution limitations?

The base model was trained on 512x512 pixel images, and image quality degrades noticeably when deviating from this resolution. Newer models like SDXL support higher resolutions.

Source
Stable Diffusion: Can I run Stable Diffusion locally on my computer?

Yes. Stable Diffusion is open-source and can run locally on compatible hardware, though it requires a GPU for reasonable performance.
