| # SF3D WebGPU Weights |
|
|
| WebGPU-ready weights for [**SF3D WebGPU**](https://github.com/lyonsno/sf3d-webgpu) — |
| a browser port of Stability AI's [Stable Fast 3D](https://huggingface.co/stabilityai/stable-fast-3d) |
| that runs single-image → textured 3D mesh generation entirely in WebGPU compute |
| shaders. No server, no Python, no ONNX at inference time. |
|
|
| This repository hosts the converted model weights so you can skip the PyTorch |
| conversion step: **clone the app, download `weights.bin`, run.** |
|

| ## Files |
|
|
| | File | Description | |
| |------|-------------| |
| | `weights.bin` | Flat fp16 binary (~2.1 GB) for direct WebGPU loading | |
| | `LICENSE.md` | Stability AI Community License (governs these weights) | |
| | `NOTICE` | Attribution + derivative-work modification notice | |
|
|
| ``` |
| SHA-256(weights.bin) = 0e5c23c8c502492c0b4432006ac30f2d11b2a4c102a3bf9f21c2fcf094ddbffd |
| ``` |
|
|
| ## Usage |
|
|
| ```bash |
| git clone https://github.com/lyonsno/sf3d-webgpu |
| cd sf3d-webgpu |
| npm install |
| |
| # Download these weights into public/ |
| hf download BasinShapers/sf3d-webgpu-weights weights.bin --local-dir public/ |
| |
| npm run dev # open http://localhost:5177/ |
| ``` |
|
|
| On an M4 Max the demo image generates a textured GLB in ~33s. See the |
| [application repo](https://github.com/lyonsno/sf3d-webgpu) for the full pipeline, |
| architecture, and PyTorch-parity receipts (the demo output is byte-for-byte |
| reproducible). |
|
|
| ## What these weights are |
|
|
| This is a **derivative work** of Stability AI's Stable Fast 3D: a format |
| conversion of the original `model.safetensors` into a single flat binary laid |
| out for WebGPU compute shaders (fp16, transposed linear weights, WebGPU-relevant |
| tensors only). The model architecture and learned values are unchanged. Full |
| details are in [`NOTICE`](NOTICE); the conversion tool is |
| [`tools/convert_weights.py`](https://github.com/lyonsno/sf3d-webgpu/blob/main/tools/convert_weights.py). |
|
|
| ## License |
|
|
| These weights are governed by the **Stability AI Community License** (see |
| [`LICENSE.md`](LICENSE.md)). In summary: |
|
|
| - **Free** for research, non-commercial, and **commercial use by organizations |
| and individuals with annual revenue of US $1,000,000 or less.** |
| - Organizations exceeding that threshold must obtain an |
| [Enterprise License](https://stability.ai/enterprise) from Stability AI before |
| commercial use of SF3D or any derivative work. |
