Streaming

Agent.stream(...) runs the same state machine as run(...) and returns a replayable AgentStreamResult:

stream = agent.stream(input="Research this topic", client=client)

for delta in stream.text_stream():
    print(delta, end="", flush=True)

completed = stream.result()

Use reasoning_stream(), item_stream(), tool_stream(), or full_stream() for other projections. Python items are currently dictionary-shaped rather than a native discriminated union. Call cancel() to stop the active model stream and pass cancellation into local runtime work.
