Stability AI
Open-source image model powering thousands of self-hosted tools
Stable Diffusion is the foundational open-source image generation model from Stability AI. Because its weights are publicly available, it powers an enormous ecosystem of fine-tuned models, LoRAs, and tools like ComfyUI, Automatic1111, and InvokeAI. SDXL and SD3 are the latest major versions with improved quality.
Open weights power a massive ecosystem of custom fine-tuned community models.
