+# whisper-large-v3-atco2-asr-mlx
+
+MLX (float16) build of [`jlvdoorn/whisper-large-v3-atco2-asr`](https://huggingface.co/jlvdoorn/whisper-large-v3-atco2-asr) for Apple Silicon inference via [`mlx-whisper`](https://github.com/ml-explore/mlx-examples/tree/main/whisper).
+
+The base model is an aviation-fine-tuned Whisper-large-v3 that reports ~17% WER on ATCO2 vs ~37–55% WER for stock large-v3 on the same domain. No public MLX conversion existed at conversion time (2026-04), so this repo exists to unblock MPS evaluation.
+
+## Usage
+
+```python
+import mlx_whisper
+
+result = mlx_whisper.transcribe(
+    "audio.wav",
+    path_or_hf_repo="sfabriece/whisper-large-v3-atco2-asr-mlx",
+    language="en",
+)
+print(result["text"])
+```
+
+## Conversion
+
+Converted with the `mlx-examples/whisper/convert.py` script:
+
+```bash
+python convert.py \
+  --torch-name-or-path jlvdoorn/whisper-large-v3-atco2-asr \
+  --mlx-path ./whisper-large-v3-atco2-asr-mlx \
+  --dtype float16
+# then rename model.safetensors → weights.safetensors (mlx-whisper loader expects this name)
+```
