Voice model

Your GPU

On this page

Have an NVIDIA GPU? Run the OmniVoice voice model right on your PC: no usage limits, no cloud account.

Requirements

  • Windows 10 or 11, or 64-bit (x86_64) Linux.
  • An NVIDIA GPU, GTX 1060 or newer, with a recent NVIDIA driver.
  • About 10 GB of free disk space.
  • The Neko Dub extension installed.

Steps

  1. Download the file for your system and put it on a drive with ~10 GB free (e.g. the D: drive):
  2. Run it:
    • Windows: double-click the file. If Windows shows Windows protected your PC, click More info → Run anyway.
    • Linux: open a terminal where you saved the file and run bash NekoDub-GPU.sh.
  3. The first run downloads ~6.5 GB. Keep the window open until it shows READY. Later runs start in seconds.

That’s it. While the window is open, Neko Dub dubs with your GPU automatically. If you also set up Modal or Colab, your own GPU is always used first.

Daily use

  • Start: run the file again and wait for READY.
  • Stop: close the window (on Linux, press Ctrl+C).
  • VRAM: after 3 minutes without dubbing, the model unloads to free VRAM for games or other apps. The window stays open; the next dub loads the model again, which takes a few seconds.

FAQ

The window shows a red error. What do I do?

Close the window and run the file again: finished steps are skipped and downloads resume. If it says nvidia-smi did not run, install the latest driver from nvidia.com/drivers first.

Does it work on Mac or AMD GPUs?

Not yet. Only NVIDIA GPUs on Windows or Linux are supported.

Can I check that the server is running?

Open http://127.0.0.1:7860/api/health in your browser. If it shows "ok": true, the server is up.

Can other computers on my network use this GPU?

Yes. Start the server with --host 0.0.0.0: on Windows, open a terminal where you saved the file and run NekoDub-GPU.bat --host 0.0.0.0; on Linux, run bash NekoDub-GPU.sh --host 0.0.0.0. Then paste http://<this-machine-LAN-IP>:7860 into Neko Dub on the other computer. If Windows Firewall asks, allow access. There is no password, so only do this on a network you trust.

How do I uninstall it?

Close the window, then delete the file you downloaded (NekoDub-GPU.bat or .sh) and the neko-omnivoice-data folder next to it. Nothing is installed anywhere else.
