Enum MessagePhase 

pub enum MessagePhase {
    Commentary,
    FinalAnswer,
}

Available on crate feature response-types only.

Labels an assistant message as intermediate commentary or the 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.
