Is possible to stream the text response while agent generating the content lively?

Response from ADK Answering Agent (experimental, answer may be inaccurate)

TLDR: Yes, text streaming is a native feature of ADK and is enabled by default. You can use the Runner.run_live() method for a bidirectional streaming interface.

Hello! Yes, it is possible to stream the text response as the agent generates it. This is a core feature of ADK designed to support real-time, interactive experiences. [2]

ADK provides native support for bidirectional streaming of both text and audio. For Python applications, you can use the Runner.run_live() method to establish a bidi-streaming connection with your agent.

The documentation provides several examples of how to implement streaming agents:

• Quickstart for Streaming Agents: There are quickstart guides for both Python and Java that demonstrate how to set up a simple streaming agent. [3]
• Custom Streaming with WebSockets: ADK supports streaming over WebSockets, and there's an example of how to implement this with FastAPI. [1]
• Java ADK: For Java agents, text streaming is an ADK Agent feature by default and does not require any specific code in the agent itself.

For more detailed information, you can refer to the ADK documentation on streaming.

Real-time text streaming is natively integrated into ADK Python by passing RunConfig(streaming_mode=StreamingMode.SSE) into runner.run_async(), consuming progressive chunks where event.partial=True.
For bidirectional voice/video interactions, StreamingMode.BIDI is also supported.
