What we know about MegaTTS3

MegaTTS3 is a text-to-speech apis platform: research-grade Apache-2.0 TTS whose practical cloning is gated: the WaveVAE encoder is not released, so users must submit audio to ByteDance channels to obtain pre-extracted speaker latents (.npy) for cloning. This profile tracks what we have verified about MegaTTS3, each fact linked to a primary source and dated.

MegaTTS3 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 MegaTTS3 quote, it is the fastest way for us to close that gap.

On capabilities, MegaTTS3 covers instant voice cloning, emotion / style controls, and self-host / on-prem option. Each of those is verified against MegaTTS3's own docs or dashboard, not marketing copy.

In total we track 11 verified facts for MegaTTS3 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 MegaTTS3 fact sheet below, and each row links the primary source it came from so you can check our work.

Whether MegaTTS3 is the right call depends on your use case more than any single spec, which is why the head-to-head verdicts below score it per scenario rather than crowning one overall winner. Use the fact sheet for the raw numbers, and the matchups for how MegaTTS3 actually fares against the platforms buyers most often weigh it against.
