Type Declaration

Optionaltemplate?: TemplatingChatMessage

For dynamic templating (changing per request), pass templated messages directly in .chatCompletion({ messages }).
Example
```
// Static template: passed once in client config
templating: {
  template: [
    {
      role: 'system',
      content: 'You are a helpful assistant for {{?product}}.'
    }
  ]
}
```
