1300 Whether to incrementally stream the response using server-sent events.
1304 Whether to incrementally stream the response using server-sent events. When `true`, SDKs return a raw event stream.

1302 See [streaming](https://platform.claude.com/docs/en/build-with-claude/streaming) for details.
1306 In the TypeScript, Python and Ruby SDKs, the recommended way to stream is `messages.stream()`. It sets `stream` for you and accumulates the events into the final message. See [Streaming with SDKs](https://platform.claude.com/docs/en/build-with-claude/streaming#streaming-with-sdks) for an example in each language.
