# SpecializationOptions

```
struct SpecializationOptions
```

## Topics

### Using preset options

[`default`](/documentation/CoreAI/SpecializationOptions/default)

Options that allow the model to use all available compute units.

[`cpuOnly`](/documentation/CoreAI/SpecializationOptions/cpuOnly)

Options that restrict compute to the CPU only.

### Creating custom options

[`init(preferredComputeUnitKind:)`](/documentation/CoreAI/SpecializationOptions/init(preferredComputeUnitKind:))

Creates options with a preferred compute unit kind.

### Configuring compute units

[`allowedComputeUnitKinds`](/documentation/CoreAI/SpecializationOptions/allowedComputeUnitKinds)

The set of compute units the specialized model can use.

[`preferredComputeUnitKind`](/documentation/CoreAI/SpecializationOptions/preferredComputeUnitKind)

The preferred compute unit kind, if one was specified.

### Configuring specialization behavior

[`expectFrequentReshapes`](/documentation/CoreAI/SpecializationOptions/expectFrequentReshapes)

Setting to allow more optimal specialization if the model performs frequent reshapes based on usage
