From registration to actual use - step by step
Stable Diffusion is open-source with multiple deployment options: local install (free, needs NVIDIA GPU 8GB+ VRAM), cloud (Replicate, RunPod), or online platforms (Civitai, SeaArt).
Visit Stability AINo GPU? Use Google Colab free tier, or try online platforms like SeaArt/Tensor.art for full SD capabilities without setup.
For local deployment, Automatic1111 WebUI is recommended. Clone the GitHub repo and run webui-user.bat (Windows); it auto-installs Python dependencies and base models. Access at localhost:7860.
Set COMMANDLINE_ARGS=--xformers --medvram in webui-user.bat to reduce VRAM usage and speed up generation. Works even with 4GB VRAM.
Download community models from Civitai (civitai.com). Base models like SDXL, Realistic Vision; style LoRAs for anime, oil painting, specific characters. Place .safetensors files in models/Stable-diffusion or models/Lora.
Browse Civitai ModelsPrefer .safetensors format over .ckpt when downloading models — safer against malicious pickle code execution.
Use comma-separated English keywords, positives first, negatives after (e.g., lowres, blurry, deformed). Install ControlNet extension to control poses and composition via skeleton, depth, or line art.
Use the Tokenizer extension to view token weights. The (keyword:1.3) syntax boosts specific elements — key for fine control.
