AG-UI 1.0
An open event protocol for communication between agents and frontends, initiated and standardized by the CopilotKit team. It defines event types such as run lifecycle, text deltas, and tool calls, and is typically carried over SSE.

AG-UI 1.0's event model covers three core categories of data: streaming tokens, tool calls, and UI parts.
For teams building agent applications, the selection process should first adopt AI SDK 7's UI message streams to revamp token streams, then introduce resumable streams to address connection stability for long tasks, and finally evaluate the AG-UI 1.0 event protocol to support cross-framework collaboration.
