If you have an NVIDIA GPU with 8GB+ VRAM, running Stable Diffusion locally is unbeatable — truly unlimited, free generation with full customization. For everyone else, cloud options provide accessible alternatives at various price points.
Yes — the model weights and code are open source. You can download and run Stable Diffusion on your own computer for free. You only pay for hardware (if you need to buy a GPU) and electricity. Cloud services charge for convenience.
Minimum: NVIDIA GPU with 8GB VRAM (like RTX 3060 12GB or RTX 4060). Recommended: 12GB+ VRAM for comfortable generation. AMD GPU support exists but is less optimized. Apple Silicon Macs can also run SD via optimized tools.
Yes — images generated with Stable Diffusion models under their standard license are free for commercial use. Some specific fine-tuned models may have different licenses, so check the specific model you're using.
