Stable Fast 3D
Turns a single image into a textured, UV-unwrapped 3D mesh in under a second.
About
Stable Fast 3D turns a single image into a textured, UV-unwrapped 3D mesh in under a second, building on the TripoSR architecture with rework aimed at game-engine-ready output. Beyond raw geometry it performs mesh quality optimization, generates textures with proper UV unwrapping rather than vertex colors, disentangles illumination from surface appearance, and predicts material parameters, so exported assets drop into rendering pipelines with less cleanup. Inference for a single image needs roughly 6 GB of VRAM with default options, and the repo includes experimental support for Windows and for Apple Silicon via the MPS backend plus a ComfyUI integration. Installation follows the usual clone and pip install requirements path on Python 3.8 or newer, though the model weights are gated on Hugging Face and require an account token to download. Stability AI distributes it under the Stability AI Community License: free for research, non-commercial, and commercial use while you and your affiliates stay under 1 million dollars in annual revenue, beyond which an enterprise license is required. The repository holds about 1.8k stars.
Should you use Stable Fast 3D?
Pick it when
Pick Stable Fast 3D when you need engine-ready meshes from single images at volume: UV-unwrapped textures, material estimates, and delighting in under a second on about 6 GB, with a ComfyUI integration and experimental Apple Silicon support.
Look elsewhere when
Skip it if your organization tops 1 million dollars in annual revenue, which requires an enterprise license, or you cannot use gated Hugging Face weights. TripoSR is MIT and ungated, and TRELLIS.2 gives full PBR on complex topology.
Alternatives to Stable Fast 3D
- TripoSR
The base architecture it builds on, MIT code and weights with no revenue cap or gating, but no material prediction or delighting.
- TRELLIS.2
Full PBR materials with preserved thin structures under MIT and no revenue cap, but needs about 24 GB versus 6 GB here.
- Hunyuan3D-2
Separate shape and texture models plus a Blender addon and API server, at 16 GB for the full pipeline and a territory-limited license.
- InstantMesh
Apache-2.0 with no revenue cap and a multi-view diffusion stage for unseen sides, but needs about 8 GB and returns no material estimates.
