Overview
Civitai is the largest open-source AI image model community on the web, hosting more than 200,000 community-trained checkpoints, LoRAs, embeddings, and fine-tunes spanning Stable Diffusion, Flux, SDXL, and Illustrious-based families. Launched in 2022, it works as part museum, part social network, and part hosted generator: you can download models to run locally in ComfyUI or Automatic1111, or generate directly in the browser using Buzz, the platform’s internal currency earned through daily logins and community activity. The defining feature is radical transparency — every sample image on every model page exposes its full prompt, negative prompt, sampler, CFG, seed, and LoRA stack, so you learn prompt engineering just by scrolling. In 2026 Civitai split its content: the main site is now advertiser-friendly while unrestricted material lives on a separate domain. For Stable Diffusion power users who want niche aesthetics and character LoRAs, it is effectively the default library.
Key Features
- 200,000+ open models — Browse and download community checkpoints, LoRAs, and embeddings for every sub-style, from anime Pony to photorealistic SDXL.
- On-site generator — Create images in the browser with Buzz credits; no GPU required for cloud generation.
- Full prompt transparency — Every sample reveals its exact prompt, seed, sampler, and settings, turning the feed into a free tutorial.
- LoRA training — Train custom LoRAs on-platform and share them with the community.
- Buzz economy — Earn free daily Buzz through logins and posts, or buy à la carte packs (~1,000 Buzz per $1).
- Membership tiers — Bronze/Silver/Gold add monthly Buzz, private models, larger batches, and vault storage.

Comparison
vs. Midjourney: Midjourney delivers more polished, curated output with far less effort, but it is a black box — you cannot see or reuse the exact recipe. Civitai trades that polish for total transparency and the deepest model library, which is why Stable Diffusion veterans prefer it for control.
vs. Leonardo AI: Leonardo AI is a cleaner, more guided generation studio with its own model roster and asset pipelines. Civitai is the better source when you want to download raw community models and run them anywhere.
vs. Stable Diffusion: Stable Diffusion is the open engine underneath most Civitai models. Use Civitai to discover, manage, and generate with those models without standing up your own local stack.
