This repository provides a standalone dots.tts artifact for **fixed one-step inference**.
The sampling contract is stored in `config.json` and selected automatically.
Sampling options should be omitted.

## Quick start

Install dots.tts from its official repository, then load this artifact exactly
like a standard dots.tts model:

```python
from dots_tts.runtime import DotsTtsRuntime
import soundfile as sf

runtime = DotsTtsRuntime.from_pretrained(
    "dots-studio/dots.tts-mf-1step",
    precision="bfloat16",
)

result = runtime.generate(
    text="Hello, this is a one-step synthesis test.",
    prompt_audio_path="reference.wav",
    prompt_text="The exact transcript of the reference audio.",
)
sf.write("output.wav", result["audio"].float().cpu().squeeze().numpy(), result["sample_rate"])
```

## Scope and limitations

This model was optimized for the fixed one-step path. Multi-step quality is not
claimed. A fresh public benchmark evaluation is not included in this artifact.
High-fidelity voice cloning must be used only with authorization and consent;
do not use it for impersonation, fraud, or disinformation.
