# ComputeUnitKind

A type of hardware compute unit available for model inference.

## Declaration

```swift
enum ComputeUnitKind
```

## Overview

Overview You use compute unit kinds with SpecializationOptions to control which hardware the framework targets when specializing a model. By default, specialization uses all available compute units on the device.
