Patterns this framework supports natively

• ★★ Streaming Typed Events — Push partial results to the client as typed events as they become available, rather than waiting for the full response.
• ★★ Tool Use — Let the LLM produce typed calls against an external toolkit instead of producing free-form text the surrounding system has to parse.
• ★★ Structured Output — Constrain the model's output to conform to a JSON Schema (or similar typed shape).
• ★★ Stop / Cancel — Let the user interrupt an in-flight agent run cleanly, releasing resources and surfacing partial state.
• ★★ Citation Streaming — Stream citations alongside generated text so the UI can render source links in place as content appears.
• ★★ Parallel Tool Calls — Allow the model to emit several independent tool calls in one assistant turn; the host executes them in parallel.
