| # TokForge — SDXL-Turbo (Qualcomm Hexagon NPU) |
|
|
| **SDXL-Turbo** image generation for the **Qualcomm Hexagon NPU (HTP)**, packaged for **on-device** |
| image generation in the **TokForge** Android app (`dev.tokforge`). This is the higher-quality |
| **1024×1024** tier alongside the SD1.5 NPU bundle. |
|
|
| The model is quantized to **W8A16** (8-bit weights, 16-bit activations) and compiled to **QNN HTP |
| context binaries** that run on the phone's Hexagon DSP. The pipeline uses **fp16 text encoders** and a |
| **TAESDXL** tiny-VAE decoder, and is **guidance-free** (few-step distilled, one UNet pass per step). |
|
|
| ## Based on |
|
|
| [`stabilityai/sdxl-turbo`](https://huggingface.co/stabilityai/sdxl-turbo). |
|
|
| ## Format |
|
|
| **QNN HTP context binaries** (W8A16), native **1024px** (128×128 latent). These are compiled for the |
| Hexagon DSP and are **not** a portable format like GGUF. The shipping set is V75-native and is |
| **forward-compatible** (a lower-arch binary also runs on a higher-arch DSP), covering Hexagon |
| **V73 → V81**. |
|
|
| | Stage | File | |
| |-------|------| |
| | CLIP-L text encoder (fp16) | `text_encoder_1_fp16.bin` | |
| | OpenCLIP-bigG text encoder (fp16) | `text_encoder_2_fp16.bin` | |
| | combined embedding MLP | `sdxl_emb_mlp.bin` | |
| | UNet | `unet.bin` | |
| | VAE decode (TAESDXL tiny-VAE) | `taesdxl_decoder.mnn` | |
| | tokenizers | `tokenizer/`, `tokenizer_2/` | |
|
|
| See `manifest.json` for the authoritative file set (with per-file size + md5) that the app uses to |
| download the bundle. |
|
|
| ## Usage |
|
|
| This bundle is loaded automatically by the TokForge Android app — it is not a standalone diffusers |
| checkpoint. The app downloads the file set from `manifest.json` and runs the binaries on the device NPU. |
