WebSocket Streaming
WebSocket streaming uses the WebSocket protocol to establish a persistent, full-duplex communication channel between the client and server, enabling real-time bidirectional data flow. In AI applications, WebSockets stream LLM-generated tokens to the client as they are produced, providing a responsive 'typing' experience rather than waiting for the complete response. WebSockets also allow the client to send interruption signals (stop generation) and receive structured events (tool calls, status updates) during agent execution. They are the preferred transport for interactive AI chat applications.
