Civitai
Community-driven AI model sharing tool.
What is Civitai?
Civitai is a community-driven platform for discovering, sharing, and collaborating on AI models, primarily focused on generative AI including image generation models. It functions as a decentralized hub where creators can upload, version, and showcase their custom-trained models alongside detailed documentation, example outputs, and user reviews. The platform emphasizes community governance and open-source principles, allowing users to access thousands of community-created models that extend the capabilities of popular AI frameworks like Stable Diffusion. Civitai is designed for AI enthusiasts, artists, developers, and researchers who want to use pre-trained models without building from scratch, as well as for model creators seeking to share their work with a global audience. The platform has become a vital resource in the open-source AI ecosystem, democratizing access to specialise models for various creative and technical applications.
