# praxis-models

Model assets redistributed for the **Praxis** language-learning app.

**This repository contains no original work.** Every file here is a byte-for-byte
copy of an upstream release, re-hosted only so the app has a stable, version-pinned
download source. Nothing has been re-trained, re-quantized, or otherwise modified.

## Why re-host at all?

The app downloads models on demand and verifies them with a SHA-256 that is
compiled into the client. Pointing directly at an upstream repository would mean
that any upstream change — a re-export, a file rename, a repository removal —
silently breaks downloads for every already-shipped client. Re-hosting gives us a
path we control; upstream is kept as a fallback mirror.

## Contents

### `sense-voice/` — SenseVoice ASR (int8)

| File | Size (bytes) | SHA-256 |
|---|---|---|
| `model.int8.onnx` | 239,233,841 | `c71f0ce00bec95b07744e116345e33d8cbbe08cef896382cf907bf4b51a2cd51` |
| `tokens.txt` | 315,894 | `f449eb28dc567533d7fa59be34e2abca8784f771850c78a47fb731a31429a1dc` |

— ONNX export of [SenseVoice](https://github.com/FunAudioLLM/SenseVoice) by FunAudioLLM,
exported for [sherpa-onnx](https://github.com/k2-fsa/sherpa-onnx) by Fangjun Kuang.

The SHA-256 of `model.int8.onnx` matches the upstream LFS pointer exactly, which is
the check we use to confirm these are unmodified copies.

Languages: Chinese, English, Japanese, Korean, Cantonese.

### `mt-qwen3-1.7b/` — Qwen3-1.7B machine translation (GGUF, Q4_K_M)

| File | Size (bytes) | SHA-256 |
|---|---|---|
| `Qwen3-1.7B-Q4_K_M.gguf` | 1,107,409,472 | `b139949c5bd74937ad8ed8c8cf3d9ffb1e99c866c823204dc42c0d91fa181897` |

**Source:** [`unsloth/Qwen3-1.7B-GGUF`](https://huggingface.co/unsloth/Qwen3-1.7B-GGUF)
(revision `d7f544eead698dbd1f15126ef60b45a1e1933222`, file `Qwen3-1.7B-Q4_K_M.gguf`) —
GGUF quantization of [Qwen3-1.7B](https://huggingface.co/Qwen/Qwen3-1.7B) by the Qwen team,
quantized by Unsloth. Runs via llama.cpp.

The SHA-256 matches the upstream LFS pointer exactly.

Used for on-device translation so the app works offline and without per-request API cost.

## Verifying

```bash
sha256sum model.int8.onnx tokens.txt
```

Any mismatch means the file was corrupted in transit or tampered with — do not use it.
