## Union Discrimination

Use the `Type` field to determine which variant is active, then access the corresponding field:

```go lines theme={null}
switch chatContentItems.Type {
	case components.ChatContentItemsTypeFile:
		// chatContentItems.ChatContentFile is populated
	case components.ChatContentItemsTypeImageURL:
		// chatContentItems.ChatContentImage is populated
	case components.ChatContentItemsTypeInputAudio:
		// chatContentItems.ChatContentAudio is populated
	case components.ChatContentItemsTypeInputVideo:
		// chatContentItems.LegacyChatContentVideo is populated
	case components.ChatContentItemsTypeText:
		// chatContentItems.ChatContentText is populated
	case components.ChatContentItemsTypeVideoURL:
		// chatContentItems.ChatContentVideo is populated
	default:
		// Unknown type - use chatContentItems.GetUnknownRaw() for raw JSON
}
```
