This profile tracks what we have verified about Kyutai TTS, each fact linked to a primary source and dated.

Kyutai TTS does not publish a public per-minute rate we have been able to verify, so the price figure here stays blank until we can confirm one. We would rather show nothing than a guessed number; if you have a current Kyutai TTS quote, it is the fastest way for us to close that gap.

On capabilities, Kyutai TTS covers streaming audio output, instant voice cloning, and self-host / on-prem option. Each of those is verified against Kyutai TTS's own docs or dashboard, not marketing copy.

In total we track 10 verified facts for Kyutai TTS today, and add coverage as the ingestion pass revisits it. Where a number is a vendor claim rather than our own measurement, it is labeled as such on the Kyutai TTS fact sheet below, and each row links the primary source it came from so you can check our work.
