# Mega-ASR MLX Q4

This is a private MLX conversion of `zhifeixie/Mega-ASR`.

The checkpoint was produced by merging the `mega-asr-merged` LoRA adapter from
`zhifeixie/Mega-ASR` into the bundled `Qwen3-ASR-1.7B` base checkpoint, then
converting the merged weights to the `mlx-audio` Qwen3-ASR layout.

## Conversion

- Base/source repo: `zhifeixie/Mega-ASR`
- Adapter: `mega-asr-merged`
- Format: MLX / `mlx-audio`
- Quantization: affine Q4, `group_size=64`, `bits=4`
- Text model and token embedding are quantized; audio tower remains full precision.

## Use With mlx-audio

```bash
pip install -U mlx-audio
python -m mlx_audio.stt.generate --model runfuture/Mega-ASR-MLX-Q4 --audio audio.wav
```
