# ONNX Magpie Runtime Bundle

This repository contains ONNX Runtime artifacts for a local MagpieTTS conversion.
It is intended for use with the `onnx-magpie` runtime and does not require NeMo
or PyTorch at inference time.

## Files

- `magpie.pipeline.json`: runtime pipeline manifest.
- `magpie_text_context.onnx`: text/speaker context graph.
- `magpie_decoder_prefix.onnx`: autoregressive decoder prefix graph.
- `magpie_codec_decoder.onnx`: codec-token to waveform graph.
- `magpie.pipeline.kv-cache.json`: optional explicit-KV decoder pipeline manifest.
- `tokenizers/`: dependency-free tokenizer artifacts.
- `onnx-magpie-hub.json`: download manifest consumed by the runtime.

## Runtime

```powershell
python scripts/run_onnx_magpie.py --hf-repo mweinbach1/onnx-magpie --text "Hello world." --wav-output speech.wav
```

The original MagpieTTS checkpoint is governed by NVIDIA's model license. Verify
that your use of these converted artifacts complies with the upstream terms.
