How to run it
I can set this up end to end: pick the model size, deploy it on your server and connect it to your systems. Quantization compresses a model so it takes less video memory and runs on more modest hardware. Answers change slightly, so quality is checked on your own examples.
Frequently asked questions
Can Orpheus TTS be used in a commercial project?
Yes. License: Apache 2.0. It allows commercial use, but it is still worth having a lawyer review the license before launch.
What hardware does Orpheus TTS need?
At minimum: Laptop or regular PC, up to 8 GB of VRAM — smaller versions. Without a GPU the model is not practical. You can calculate the exact VRAM for your model size and context in the hardware calculator.
Does Orpheus TTS support Russian?
No. The model card lists its languages and Russian is not among them.
Where can I download Orpheus TTS and what does it cost?
The Orpheus TTS weights are open and free to download. You only pay for the hardware it runs on and for the setup. Source links are at the bottom of this page.
