## Numerals Now Available in Flux

### 🆕 Numeral Formatting for Flux

Flux now supports the `numerals` feature, which converts numbers from written format to numerical format (for example, "nine hundred" becomes "900"). Numerals are available on both Flux models:

- **Flux English** (`model=flux-general-en`) — full numeral formatting.
- **Flux Multilingual** (`model=flux-general-multi`) — numeral formatting for English, Spanish, French, German, Russian, Portuguese, Italian, and Dutch. Numeral formatting is not currently supported for Hindi or Japanese.

### Enabling Numerals

Set `numerals=true` as a query parameter when you open the WebSocket connection:

```text
wss://api.deepgram.com/v2/listen?model=flux-general-en&numerals=true&encoding=linear16&sample_rate=16000
```

On Flux, `numerals` is set at connection time only and cannot be changed through the `Configure` message.
