OpenAI's Responses API is emitting
prompt_cache_retention: "in_memory"on streaming events, but theopenaiSDK'sResponsepydantic model declares theLiteralas only"in-memory"/"24h"(openai-python#2883).Response.model_validate()raises inside_coerce_chunk_response, aborting the stream and forcing downstream fallback chains. Normalize the known mismatch and add an escape hatch for future drifts.Possibly related to #36899
