# Milliwatt Labs Model License

> Free for organizations with up to $1M in annual revenue. Above that, one flat, predictable yearly fee.

Version 1.0 · Effective November 8, 2026

This license covers the Leokani models from Milliwatt Labs (Leokani-tts 7M with its Dala and Pono voices, and Leokani-tts 4.5M) and every model Milliwatt Labs releases under it from now on. Milliwatt Labs is run by Emtanon LLC (“we”).

## Free up to $1M

You may use, copy, modify, fine-tune and share the models, and use the speech they make, for any purpose, including commercial use, free of charge, if your organization has up to US$1,000,000 in annual revenue.

Personal use, research, education and non-profit use are always free, with no registration.

## Commercial use

Commercial use needs a free, one-time [registration](https://milliwattlabs.com/license/register/). Once a year we email you a link with two buttons, Up to $1M and Over $1M. One tap is your yearly report.

## Above $1M

Above US$1M in annual revenue, you pay one flat, predictable yearly fee. [Contact us](mailto:hello@milliwattlabs.com) for it. The terms:

- **No royalties.** Never per-unit, per-user or usage fees.
- **One fee covers every model**, including future ones.
- **Predictable.** For existing licensees, the fee rises by at most 5% a year.
- **Grace year.** Your first year over US$1M is free.
- **Funding isn’t revenue.** Money from investors, loans and grants doesn’t count.
- **Only what uses our models counts.** Revenue means revenue from products and services that use the models.
- **No audits.** You report it yourself. A knowingly false report ends this license for you.

## Versions you’ve licensed stay yours

Your rights to every model version you got under this license last forever. If we change the license, or you stop paying a fee, the versions you already have keep the terms you got them under.

Copies downloaded before November 8, 2026 were licensed under [CC BY-NC 4.0](https://creativecommons.org/licenses/by-nc/4.0/). You may keep using them under it, or move them to this license.

## Rules that always apply

Whatever your size:

- **Consent.** Don’t make a model imitate a real person’s voice without that person’s consent.
- **No impersonation.** Don’t use the models, or speech made with them, to impersonate anyone or to make it sound like someone said something they didn’t.
- **No deception.** No scams, phishing, fake emergency or official messages, or election-related deception.
- **Keep the watermark.** Speech made with the models carries an inaudible watermark. Don’t remove, disable or defeat it, or help anyone do so.
- **Follow the law**, including privacy, consumer-protection and robocall rules. Tell people when speech is synthetic wherever the law requires it or they could reasonably be misled.

Breaking these rules ends this license for you.

## Sharing

If you share a model, or a model you made from one, include this license or a link to it. The people you share it with follow the same rules.

## What isn’t covered

Leokani G2P versions already released under MIT and CC BY 4.0 keep those licenses. Third-party parts shipped with a model keep their own licenses, listed on its page.

## No warranty

The models are provided “as is”, without warranties of any kind. Our [Terms of Use](https://milliwattlabs.com/terms/) cover warranty, liability and governing law.
