# Run Moonshine with Keras 3: JAX, PyTorch, or TensorFlow

# kerasformers/moonshine_base

Paper: [Moonshine: Speech Recognition for Live Transcription and Voice Commands (arXiv:2410.15608)](https://arxiv.org/abs/2410.15608) · [HF Papers](https://huggingface.co/papers/2410.15608)

Moonshine is an English ASR encoder-decoder built for **short / live** audio: the encoder sees the raw waveform length you pass in (no Whisper-style 30 s pad), so short commands stay cheap. Output is cased and punctuated.

For more details on the model, please go to the upstream [model card](https://huggingface.co/UsefulSensors/moonshine-base).

Pure-**Keras 3** conversion of [`UsefulSensors/moonshine-base`](https://huggingface.co/UsefulSensors/moonshine-base) for [kerasformers](https://github.com/IMvision12/KerasFormers). One implementation runs unmodified on **TensorFlow / Torch / JAX**.

This is an **ASR** checkpoint (`MoonshineConditionalGenerate`).

## ✨ Quick start

```python
import os
os.environ["KERAS_BACKEND"] = "torch"  # or "jax" / "tensorflow"

import soundfile as sf
from kerasformers.models.moonshine import (
    MoonshineProcessor,
    MoonshineConditionalGenerate,
)

model = MoonshineConditionalGenerate.from_weights("kerasformers/moonshine_base")
processor = MoonshineProcessor.from_weights("kerasformers/moonshine_base")

audio, sr = sf.read("your_audio.wav", dtype="float32")  # 16 kHz mono
# Cost scales with clip length: no fixed 30 s pad like Whisper.
text = model.generate(audio, processor)
print(repr(text[0]))
```

Load any Moonshine variant the same way with `from_weights("kerasformers/<variant>")`:

| Variant | Hub |
|---|---|
| `moonshine_tiny` | [`kerasformers/moonshine_tiny`](https://huggingface.co/kerasformers/moonshine_tiny) |
| `moonshine_base` | [`kerasformers/moonshine_base`](https://huggingface.co/kerasformers/moonshine_base) |

## Tips

- Set `KERAS_BACKEND` **before** importing Keras / kerasformers.
- Prefer `MoonshineProcessor.from_weights(...)` so feature extraction matches.
- English-only; pass a list of waveforms to batch.
- See [Moonshine docs](https://imvision12.github.io/KerasFormers/moonshine/) and [Loading Weights](https://imvision12.github.io/KerasFormers/loading_weights/).
- Community / upstream safetensors still work via the `hf:` prefix, e.g. `MoonshineConditionalGenerate.from_weights("hf:UsefulSensors/moonshine-base")`.

## Special Thanks

A huge thank you to the Useful Sensors Moonshine authors for creating and releasing these models.
