Cause (Documented platform behavior): The Live session API split into explicit client-content, realtime-input and tool-response messages. Fix status: documented_behavior Other error fragments: - Setting `AsyncSession.start_stream` is deprecated, and will be removed in a future release (not before Q3 2025). Please use the `receive`, and `send_realtime_input`, methods instead.

Recommended action: Use session.send_client_content(turns=..., turn_complete=True) for text turns, session.send_realtime_input(audio=/video=/text=) for streaming media, and session.send_tool_response(function_responses=...) for tool results. Option: Use specific send methods [evidence: official_recommended_action] Steps: 1. send_client_content for turns 2. send_realtime_input for audio/video/text streaming 3. send_tool_response for function responses Expected: No deprecation warnings Evidence basis (self-declared by the contributing chat client): untested.
