# InfraOCR models (SoMark OXR-1.0 for Snapdragon NPUs)

QNN HTP context binaries of **SoMark OXR-1.0** for the InfraOCR Android app, built with QAIRT 2.51.40.260930.
They are derived from [SoMarkAI/OXR-1.0](https://huggingface.co/SoMarkAI/OXR-1.0) and are distributed under the
same license, Apache-2.0 with SoMark's additional terms (see `LICENSE` and `NOTICE`).

| Folder | Contents |
|---|---|
| `common/` | `embed.f16` (Qwen3 embedding table), `prefix_kv.f32` (K/V of the fixed chat prefix), `vte_indicators.f32`, `pos_embed.f32` (32x32 vision position embedding), `vocab.bin` (id to bytes), `prompts.json` (token ids of the fixed prompts) |
| `sm8850/` | Snapdragon 8 Elite Gen 5 |
| `sm8950/` | Snapdragon 8 Elite Gen 6 |
| `sm8975/` | Snapdragon 8 Elite Gen 6 Pro |
| `app/` | InfraOCR APKs and `latest.json` for in-app updates |

Each SoC folder has:

| File | Model | Precision |
|---|---|---|
| `oxr_layout.bin` | D-FINE B2 layout detector, 960x960 | FP16 |
| `oxr_vis_1024.bin`, `oxr_vis_3600.bin` | SigLIP2-NaViT encoder + visual head, padded to 1024 / 3600 patches | FP16 |
| `oxr_llm.bin` | Qwen3-0.6B decoder, AR-16 prefill and AR-1 decode graphs | W8, A16, KV8 |
| `oxr_llm_head.bin` | final norm + tied lm_head | W8 |

`manifest.json` lists every file with its size and sha256.

Measured against the bf16 reference on 495 blocks from 40 OmniDocBench pages: vision 99.5% exact match at the
block level, LLM 97–98% exact match, about 145 ms per vision block and 45–60 tokens per second on SM8975.
