Specifies the device to use for hardware acceleration. cpu: no acceleration just use the CPU rocm: supported by modern AMD GPUs cuda: supported by modern NVIDIA GPUs metal: supported on darwin aarch64 machines Tabby will try and determine what type of acceleration that is already enabled in your configuration when acceleration = null. nixpkgs.config.cudaSupport nixpkgs.config.rocmSupport if stdenv.hostPlatform.isDarwin && stdenv.hostPlatform.isAarch64 IFF multiple acceleration methods are found to be enabled or if you haven’t set either cudaSupport or rocmSupport you will have to specify the device type manually here otherwise it will default to the first from the list above or to cpu.
