Spec score 7.8 #15 of 24 in AI 3D Model Generators

What it is

Stable Fast 3D turns an image of an object into a textured, UV-unwrapped 3D mesh. Stability AI describes the model as generating a 3D model from one image in under one second. It expects a 512 × 512 pixel input, applies a delighting step, and predicts roughness and metallic material parameters. The official code example saves the result as a GLB file. The repository includes custom nodes and an example workflow for ComfyUI, and API access is available. Documented inference options include CUDA, CPU, and experimental Mac MPS; Windows support is marked experimental. Default settings use about 6 GB of VRAM for one image. Stability AI identifies game and VR developers and professionals in retail, architecture, and design among its intended users. The Community License is free; commercial use above US $1 million in annual revenue requires an Enterprise License. Access to model files requires agreeing to share contact information and accepting the license.

Strong points and limits

Strong points

  • Creates a textured mesh from one object image.
  • Model page says generation takes under one second.
  • Exports GLB files.
  • Includes ComfyUI nodes and an example workflow.
  • Offers API access.

Limits

  • Expects a 512 × 512 pixel input.
  • Default settings use about 6 GB of VRAM.
  • Windows support is marked experimental.
  • Model-file access requires contact details and license acceptance.

Who it suits

It may suit game and VR developers, or professionals in retail, architecture, and design who need image-to-3D assets. Users should account for the documented input size and hardware requirements, and check the license terms for their use.

Verdict

Stable Fast 3D specifies a focused image-to-mesh workflow, including input size, output format, and documented inference options. Commercial users above the stated revenue threshold need an Enterprise License.
