Overview
What is Civitai?
Civitai is the largest open community platform for generative AI art. It hosts thousands of free AI models (Stable Diffusion, Flux, LoRAs, and more) that users can download for local use or run directly in the browser. Beyond being a model library, it works as a creative hub where users generate images, videos, and 3D models, share their work, post prompts, enter challenges, and earn rewards. The platform runs on a virtual currency called Buzz, which powers generations and rewards creators. Unrestricted adult content has been moved to a separate site (civitai.red).
