FAQ
Can I run Stable Diffusion on my computer?
Yes, you need a GPU with at least 6GB VRAM (8GB+ recommended). NVIDIA GPUs work best. Use tools like Automatic1111 or ComfyUI for a web interface.
Is Stable Diffusion really free?
Yes, the models are open source and free to use, even commercially. You only pay for hardware/cloud GPU if you don't have a local GPU.
