## Toggle Numerals Mid-Stream on Flux STT

Switch Flux STT to digits for a PIN, phone number, or order number, then back to words, without reconnecting. To turn [Numerals](/docs/numerals) on or off during a Flux STT stream, send `numerals` as a boolean in a [`Configure`](/docs/flux/configure) message:

```json
{ "type": "Configure", "numerals": true }
```

The update applies to transcripts Flux STT sends after it processes the message, and `ConfigureSuccess` now includes `numerals` in the full active configuration it echoes. The `numerals` query parameter still sets the initial value when the stream opens. This replaces the connection-time-only behavior in the [July 17 entry](/changelog/2026/7/17).

Mid-stream numerals work on `flux-general-en` and on `flux-general-multi` for English, Spanish, French, German, Russian, Portuguese, Italian, and Dutch.
