# Models

Reson8 provides multiple speech-to-text models to choose from. Models make different trade-offs between transcription quality, price, and speed, so you can pick the one that fits your use case.

Every request is transcribed by one model. Pass the `model` query parameter to choose it; when omitted, the request uses `resonant-1`.

```
?model=rumble-2-flash

### Rumble-2-Flash

A model optimized for speed on the [Prerecorded](/speech-to-text/prerecorded/) API: upload a file and get its plain transcript back. It is a good fit when you need just the text of a recording, without speaker labels, timestamps, or vocabulary customisation.
