Overview
Civitai is the world's largest AI model and image sharing community, focusing on the ecosystem of open-source image models like Stable Diffusion. It hosts hundreds of thousands of user-trained models (LoRA, Checkpoint), millions of AI-generated images, and detailed prompts—making it a 'paradise' for AI art enthusiasts.
Civitai is not just a model download platform; it also offers online image generation. You can directly use community models to generate images on the web without needing to deploy Stable Diffusion locally.
