Dedicated model · Available as managed deployment
Kokoro is an 82-million-parameter open-weight text-to-speech model with natural voices, fast enough for real-time use, under Apache-2.0. Available as a managed deployment: validated on AxForge hardware and deployed on a DGX Spark for your traffic only, as an OpenAI-compatible endpoint on hardware only you use, hosted in the EU.
Why Kokoro
| Real-time on one machine | 82M parameters: a dedicated DGX Spark synthesises speech many times faster than real time, for many concurrent streams. |
|---|---|
| Natural voices, several languages | Multiple voices and languages in one small model, with quality close to models many times its size. |
| Apache-2.0 | Permissive weights: commercial use, no licence conversation, no per-character vendor pricing. |
