 implements Enum
                    
```
Labels an assistant message as intermediate commentary (commentary) or the final answer (final_answer). For models like gpt-5.3-codex and beyond, when sending follow-up requests, preserve and resend phase on all assistant messages — dropping it can degrade performance. Not used for user messages.

Nested Class Summary

Nested Classes
Modifier and Type	Class	Description
`public enum`	`ResponseOutputMessage.Phase.Known`	An enum containing Phase's known values.
`public enum`	`ResponseOutputMessage.Phase.Value`	An enum containing Phase's known values, as well as an _UNKNOWN member. An instance of Phase can contain an unknown value in a couple of cases: It was deserialized from data that doesn't match any known member. For example, if the SDK is on an older version than the API, then the API may respond with new members that the SDK is unaware of. It was constructed with an arbitrary value using the of method.

  - _value
```
 final JsonField<String> _value()
```
    Returns this class instance's raw value.
    This is usually only useful if this instance was deserialized from data that doesn't match any known member, and you want to know that value. For example, if the SDK is on an older version than the API, then the API may respond with new members that the SDK is unaware of.
  - value
```
 final ResponseOutputMessage.Phase.Value value()
```
    Returns an enum member corresponding to this class instance's value, or Value._UNKNOWN if the class was instantiated with an unknown value.
    Use the known method instead if you're certain the value is always known or if you want to throw for the unknown case.
  - known
```
 final ResponseOutputMessage.Phase.Known known()
```
    Returns an enum member corresponding to this class instance's value.
    Use the value method instead if you're uncertain the value is always known and don't want to throw for the unknown case.
  - asString
```
 final String asString()
```
    Returns this class instance's primitive wire representation.
    This differs from the toString method because that method is primarily for debugging and generally doesn't throw.
  - validate
```
 final ResponseOutputMessage.Phase validate()
```
  - isValid
```
 final Boolean isValid()
```
  - equals
```
 Boolean equals(Object other)
```
  - hashCode
```
 Integer hashCode()
```
  - toString
```
 String toString()
```
  - of
```
 final static ResponseOutputMessage.Phase of(String value)
```
