-> Try our new model: **SF3D** with several improvements such as faster generation and more game-ready assets.
-> 
-> The model is available [here](https://huggingface.co/stabilityai/stable-fast-3d) and we also have a [demo](https://huggingface.co/spaces/stabilityai/stable-fast-3d).

-
-**TripoSR** is a state-of-the-art open-source model for **fast** feedforward 3D reconstruction from a single image, developed in collaboration between [Tripo AI](https://www.tripo3d.ai/) and [Stability AI](https://stability.ai/).
-
-**Tips:**
-1. If you find the result is unsatisfied, please try to change the foreground ratio. It might improve the results.
-2. It's better to disable "Remove Background" for the provided examples since they have been already preprocessed.
-3. Otherwise, please disable "Remove Background" option only if your input image is RGBA with transparent background, image contents are centered and occupy more than 70% of image width or height.
