Discover, download and generate with open-source AI models for image, video and 3D.
Browse one of the largest public libraries of open-source image, video and 3D AI models, with ratings, reviews, example images and download counts on every model page.
Generate images, video and 3D assets in the browser using hosted versions of featured models, no local GPU or setup required.
Search, collect and organize checkpoints, LoRAs, embeddings and ControlNet models, then compare outputs side by side before committing to a workflow.
Join challenges, events and creator leaderboards, follow top artists, remix images and share your own models with the community.

Train your own Stable Diffusion and SDXL image models in the cloud
Upload your own images and fine-tune Stable Diffusion models in the cloud using DreamBooth, including Stable Diffusion XL, without needing a local GPU.
Choose public models that the community can discover and generate from, or private models whose images stay exclusive to your account.
Every trained model becomes a generator that can produce unlimited AI assets in its learned style and subject matter.
Refine existing models with revisions and download finished weights in .CKPT (SD 1.5) or LoRA (SDXL) format for use in other tools.
