# `gpu`

## Synopsis

The `gpu` command manages GPU-related operations, including installing, enabling, disabling, and uninstalling GPU drivers and related components, as well as checking the GPU status.

```bash
olares-cli gpu <subcommand> [options]
```

:::info
- By default, the Olares installation script detects your GPU hardware and CUDA drivers, then configures and enables the GPU components and services automatically.
- Currently, only NVIDIA GPUs are supported.
