# SFCustomLanguageModelData.TemplateInsertableBuilder

A custom parameter attribute that constructs custom language model data from closures.

## Declaration

```swift
@resultBuilder struct TemplateInsertableBuilder
```

## Overview

Overview Phrase counts can be generated manually by providing an exact phrase and weight (e.g. “Play the Albin counter gambit”) or from templates (e.g. “Move my <piece> to <square>”). Templates themselves can be constructed manually, or using the result builder DSL. This type supports the latter.
