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

## Quick start

```bash
dots.tts \
  --model-name-or-path dots-studio/dots.tts-mf-2steps \
  --text "Hello, this is a two-step MeanFlow voice cloning example." \
  --prompt-audio /path/to/reference.wav \
  --prompt-text "The exact transcript spoken in the reference audio." \
  --output cloned.wav
```

```python
from dots_tts.runtime import DotsTtsRuntime

runtime = DotsTtsRuntime.from_pretrained(
    "dots-studio/dots.tts-mf-2steps",
    precision="bfloat16",
)
result = runtime.generate(
    text="Hello, this is a two-step MeanFlow voice cloning example.",
    prompt_audio_path="/path/to/reference.wav",
    prompt_text="The exact transcript spoken in the reference audio.",
)
```

Passing incompatible sampling values raises an error.

## Scope and limitations

This model is intended for fixed two-step inference. Other sampling settings are not claimed.
High-fidelity voice cloning must be used only with authorization and consent; do not use it
for impersonation, fraud, or disinformation.
