…models Enable `preserveUnknownFields` and `modelSerializationMethods` in the Python SDK. Unknown fields are kept at every nesting level, in responses and in requests: unknown request fields are forwarded instead of silently dropped, so unsupported options such as `transcription_config.diarization` are rejected by the API rather than ignored (#3162), and fields missing from the SDK schema reach the API. Unknown steps, content blocks and annotations round-trip as the payload the server sent, including stateless multi-turn history sent back as SDK objects or as stored dicts; known variants with invalid payloads still raise locally.
