}Expand description
Semantic streaming events per the Open Responses specification.
These events describe meaningful transitions during response generation, enabling predictable, provider-agnostic streaming clients.
Variants§
ResponseCreated
Initial response creation event.
ResponseInProgress
Response has started processing.
ResponseCompleted
Response completed successfully.
ResponseFailed
Response failed with an error.
ResponseIncomplete
Response is incomplete (e.g., token limit reached).
OutputItemAdded
New output item added to the response.
Fields
§
response_id: ResponseIdID of the containing response.
§
item: OutputItemThe output item being added.
OutputItemDone
