Stable Fast 3D

Stable Fast 3D generates a textured 3D asset from a single object image. Built on TripoSR, it's aimed at game and VR developers, designers and people making product models for e-commerce.

• Textured meshes: Generate a UV-unwrapped mesh with material parameters and normal maps for use in other 3D software.
• Reduced baked lighting: Produce texture colors with less of the input image's lighting baked in, so the asset carries less of that original illumination.
• Mesh adjustment and export: Optionally remesh with triangle or quad topology and export as GLB; quad meshes are split into triangles for GLB export.
• ComfyUI workflows: Use the supplied custom nodes to include image-to-3D reconstruction in a ComfyUI workflow.

The downloadable model runs locally on Linux with CUDA, and a CPU backend works without a GPU. Default inference uses about 6GB of VRAM for one image. Access to the model weights requires a Hugging Face account and approval.

Code and weights use the Stability AI Community License, which permits non-commercial use and commercial use subject to eligibility restrictions. Other commercial use requires an enterprise license.

Stability AI also provides hosted access through its API and Stable Assistant, where images are processed in the cloud. Stable Assistant includes a 3D viewer and AR viewing on WebXR-compatible devices.

Stable Fast 3D is distributed through its reference repository and downloadable model weights. Its Stability AI Community License covers code and weights and includes commercial eligibility conditions. The local release is separate from Stability AI’s hosted generation services.
