## rakeaudio: audio transcription

A second model joins `decision-machine-1` on the same API key. `POST /v1/rakeaudio/transcribe` takes an audio file as the raw request body. It returns the transcript with word timestamps and, by default, up to four speaker labels.

* 25 European languages, detected from the audio.
* Up to 60 minutes of audio per call, in one synchronous call.
* \$0.12 per audio hour with speakers, \$0.10 without (`diarize=false`), billed as input tokens.

See [rakeaudio](/rakeaudio/overview) and [Transcribe](/rakeaudio/transcribe).

## A docs layout for several models

The docs now describe milliseconds.ai as a platform. **Start here** and **Platform** cover every model. `decision-machine-1` and `rakeaudio` each have their own section. Existing page URLs do not change. The one exception is **How it works**, which moves to [/concepts/how-it-works](/concepts/how-it-works) with a redirect.
