About xAI Speech to Text

How many languages are supported?
25, with diarization and word-level timestamps available across them rather than only for English.
What does clean formatting mean here?
Punctuation and casing are applied to the transcript, so it reads properly instead of arriving as an unbroken lowercase stream.
Does it identify who is speaking?
Yes — speaker diarization is built in, which is what makes it usable for interviews and multi-party calls.
