The open-source image AI with unlimited customization
Stable Diffusion is the open-source foundation model that powers hundreds of specialized image generators. Run it locally for free, fine-tune it on your own images, or use hosted versions like Automatic1111, ComfyUI, or DreamStudio. Unmatched flexibility.
Free to run locally; DreamStudio offers free credits
Common use cases where Stable Diffusion excels
Run entirely on your own hardware — no data leaves your machine, no subscription required.
Train LoRA models on your own images to generate consistent characters, products, or styles.
Edit specific parts of images or extend them beyond their original borders.
Build complex generation pipelines with ComfyUI for batch processing and automation.
Expert techniques to get the best results from Stable Diffusion
Stable Diffusion responds strongly to negative prompts. Always add: 'ugly, blurry, low quality, watermark, text, extra limbs, deformed' to your negative prompt.
CFG 7-9 is the sweet spot for most prompts. Higher values (12+) follow the prompt more strictly but can look over-saturated. Lower values (3-5) are more creative.
Many fine-tuned models require specific trigger words (e.g., 'sks person' for DreamBooth models). Always check the model card.
