Civitai

Civitai is the largest open-source AI image generation community on the internet, serving as the central hub where creators upload, share, and discover AI models. With over 200,000 models for Stable Diffusion, Flux 2, and related architectures, it is the go-to resource for anyone working with open-source image generation.

The platform has evolved far beyond a simple model repository. Civitai now functions as a cloud generation suite, training environment, creator economy, and content community all in one. Users can generate images directly in the browser without needing a local GPU, train custom LoRA models on Civitai's cloud servers by uploading training images, and access eight distinct video engines (including Kling and Veo) from a single interface.

Most community models on Civitai are free to download and use. The platform operates on a Buzz credit system for cloud generation and training, with multiple ways to earn or purchase Buzz. Creators can monetize their models through tips and the Buzz economy.

Civitai attracts millions of monthly visitors and is particularly popular among digital artists, hobbyists, game developers, and anyone interested in the cutting edge of open-source AI image generation.
