Civitai

Civitai is the largest community platform for sharing Stable Diffusion models, LoRAs, and prompts — with an integrated online image and video generator.

Overview

Civitai started as a model-sharing hub and grew into a full creation ecosystem where users browse, review, and download checkpoints, LoRAs, embeddings, and workflows. Every model page shows example outputs, trigger words, and user reviews, making it the de-facto reference library for open image generation. Its on-site generator lets members produce images and short videos directly in the browser using community models without any local hardware.

The platform runs on a virtual currency called Buzz, earned by participating or purchased outright, and includes features like bounties, image contests, and an API for third-party tools. Content policies and mature-content filters keep the community usable for professional research as well as hobby art.

For professionals, Civitai doubles as an index of what is technically possible with open models: benchmark discussions in comments, workflow breakdowns, and side-by-side output galleries make it easier to choose a model for a specific task than trial-and-error downloading. Buzz incentives keep high-quality resources flowing.

Pricing

Browsing and downloading many models is free, while on-site generation consumes Buzz. Buzz can be earned through community activity or bought in packs, and subscription tiers add monthly Buzz stipends and perks. Subscription tiers add monthly Buzz stipends, early feature access, and perks for heavy generators without forcing per-image metering.

Who Is It For

Civitai is essential for Stable Diffusion users, AI artists, and developers who want the widest possible choice of styles and models.

It is equally useful for researchers tracking the open model ecosystem.

Product teams also monitor Civitai to track which open models are becoming industry standards before adopting them commercially.
