## What we know about F5-TTS

This is our verified profile of F5-TTS, a text-to-speech apis platform - the go-to research-grade voice-cloning model - actively maintained and broadly ported, with the classic code-vs-weights license split: commercial products must retrain or license around the CC-BY-NC checkpoints. Every fact about F5-TTS below carries the source it came from and the day we checked it.

F5-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 F5-TTS quote, it is the fastest way for us to close that gap.

On capabilities, F5-TTS covers streaming audio output, instant voice cloning, emotion / style controls, and self-host / on-prem option. Each of those is verified against F5-TTS's own docs or dashboard, not marketing copy.

In total we track 9 verified facts for F5-TTS today, each linking the primary source it came from so you can check our work - and vendor claims we have not measured ourselves are labeled as such on the F5-TTS fact sheet below.
