GPU and CUDA

GPU & CUDA

TypeWhisper ships an optional CUDA backend that runs the bundled whisper.cpp transcription engine on a compatible NVIDIA GPU. This page covers what it requires and what it currently applies to.

Requirements

To use the CUDA backend you need:

• An NVIDIA GPU and driver.
• CUDA 12 runtime/toolkit libraries providing libcudart.so.12 and libcublas.so.12.

If those libraries are missing, the Linux UI disables the relevant control and explains what's needed — see Troubleshooting.

Scope

CUDA currently applies to the bundled whisper.cpp engine. Other bundled local engines stay on CPU.
