| # Stable Diffusion 1.5 — ONNX FP16 (sona-forge mirror) |
|
|
| Mirror of the Stable Diffusion 1.5 ONNX FP16 weights bundled with the |
| [Sona Forge](https://github.com/virtaava/mobile-ai-image-app) Android app. |
|
|
| The local-first Sona Forge architecture requires every binary the app fetches |
| at runtime to live on a single, stable mirror under |
| [`huggingface.co/sona-forge`](https://huggingface.co/sona-forge), so that a |
| provider-side change (account rename, file deletion, hash drift) cannot break |
| end-user installs. |
|
|
| ## Provenance |
|
|
| These files are byte-identical mirrors of: |
|
|
| - `nmkd/stable-diffusion-1.5-onnx-fp16` @ `38dacf2c14c89e3538b5e32da888eb9c46e0e1bf` |
|
|
| which itself is an ONNX FP16 conversion of the Stable Diffusion 1.5 weights |
| originally released by Runway and CompVis under the |
| [CreativeML Open RAIL-M](https://huggingface.co/spaces/CompVis/stable-diffusion-license) |
| licence. The licence is preserved in the Sona Forge in-app |
| "Open-source notices" screen. |
|
|
| ## Layout |
|
|
| ``` |
| text_encoder/model.onnx 246 MB text encoder |
| unet/model.onnx 1 MB unet graph (external-data references weights.pb) |
| unet/weights.pb 1.7 GB unet weights (external data) |
| vae_decoder/model.onnx 99 MB vae decoder |
| vae_encoder/model.onnx 68 MB vae encoder |
| tokenizer/ CLIP BPE tokenizer (vocab, merges) |
| scheduler/ DDIM scheduler config |
| model_index.json diffusers pipeline manifest |
| ``` |
|
|
| `unet/model.onnx` references `weights.pb` via ONNX external-data, so both |
| files must live in the same `unet/` subdirectory at load time. |
|
|
| ## SHA-256 manifest |
|
|
| The Sona Forge app verifies every file against a per-file SHA-256 declared in |
| `app/src/main/assets/model_manifests/manifest.json` before loading it. If the |
| content of this mirror ever drifts from what the app expects, the download |
| will fail-closed with a hash mismatch — Toni will know before any user does. |
