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.
Turn rough sketches into refined AI images
Use the built-in canvas to draw your idea, or upload an existing sketch, then submit it with a text prompt. The service renders a refined image that follows both the shapes you drew and the description you typed.
Iterate by changing the prompt while keeping the same drawing, so a single sketch can branch into several visual directions — different colours, styles, materials or lighting on the same composition.
Images are returned in a high-quality format and paid plans prioritise generation speed, so you are not waiting on long queues when you are working through a set of ideas.
A public Explore gallery shows what other users have produced, which is a quick way to understand the range of styles the model handles before you commit to a credit purchase.
