Server-Sent Events
Server-Sent Events (SSE) is a web technology that streams real-time updates from server to client over a single HTTP connection.
Streaming improves perceived latency and UX for AI assistants—especially when retrieval/tool steps add waiting time.
Explanation
SSE is often used for LLM response streaming because it's simpler than WebSockets for one-way server→client token streams.
