Stable Fast 3D (SF3D) is Stability AI's open-source model that reconstructs a textured, UV-unwrapped 3D mesh from a single input image in about half a second. It builds on TripoSR and adds UV unwrapping, material parameter prediction, and illumination delighting so assets are ready for games and other rendering pipelines.

Use cases

• generate a 3d model from a single photo
• image to 3d mesh reconstruction
• create game-ready textured 3d assets from images
• unwrap uv textures for a reconstructed mesh
• remove lighting from a photo before 3d reconstruction
• fast 3d asset generation for game development

When to choose

• you need fast (sub-second) single-image to 3D mesh generation
• you need UV-unwrapped textured meshes with material parameters for game or rendering pipelines
• you want an open-source alternative to commercial image-to-3D services
• you have a CUDA GPU (or experimental Apple MPS support) available

When to avoid

• you need high-fidelity 3D from multiple views or video rather than a single image
• you require a permissive license - the model weights are gated under a custom Stability AI license
• you have no GPU and need production-quality speed
• you need precise CAD-quality geometry rather than approximate visual meshes
