# chattts (Vokra GGUF)

Converted to the Vokra GGUF format for [Vokra](https://github.com/ayutaz/vokra), a zero-dependency speech-AI inference runtime.

**This is a conversion, not a new model.** The weights are the upstream ones; Vokra re-packages them so its runtime can memory-map them directly. Credit for the model belongs upstream — see *Source* below.

Every row above is read out of this file's own `vokra.*` metadata, so the card cannot claim something the artifact does not carry.

## Licence

The weights are distributed under **cc-by-nc-4.0**, unchanged from upstream. Conversion does not alter the licence, and your obligations run to the upstream author.

### ⛔ Non-commercial — you may not use this weight commercially

The upstream weight is **cc-by-nc-4.0**. It is republished here so the model can be evaluated and used for research, and the licence is unchanged by conversion.

- **Do not use this in a commercial product or service.** That restriction is upstream's, not Vokra's, and Vokra cannot waive it.
- Vokra's engine is Apache-2.0 and imposes no such limit — the limit is on **this weight**. Other models in this organisation are permissively licensed; check each one's card.
- Vokra's runtime refuses to load a non-commercial weight unless an explicit research flag is set, so this restriction is enforced at load time rather than left to the reader.
