Introducing our Conformer-1 model

We've released our new Conformer-1 model for speech recognition. Conformer-1 was trained on 650K hours of audio data and is our most accurate model to date.

Conformer-1 is now the default model for all English audio files sent to the /v2/transcript endpoint for async processing.

We'll be releasing it for real-time English transcriptions within the next two weeks, and will add support for more languages soon.
