AG-UI (Agent-User Interaction Protocol) is the open, lightweight standard for streaming real-time, bi-directional JSON events between any AI agent backend and a user-facing frontend.

AG-UI is the Agent-User Interaction Protocol: a standardized, event-based layer that solves the 'last mile' problem for AI agents. It operates over standard web transports like HTTP and Server-Sent Events (SSE), streaming a single, ordered sequence of JSON events—specifically, messages, tool calls, and state patches—to maintain perfect real-time synchronization between your agent and the UI . This open protocol eliminates the need for custom WebSocket formats or ad-hoc integrations, ensuring backend flexibility: you can swap between models like OpenAI, Ollama, or LangGraph without touching the frontend . Implementations are available via TypeScript and Python SDKs, making it the definitive contract for building reliable, production-ready agentic applications .

## Recent Public Talks and Demos

### [Playing with Multi-agent User Interfaces](https://nyc.aitinkerers.org/talks/rsvp_eRYOqSoiYFo)

I've been playing around with multi-agent systems, how they fit in to using multiple frameworks and what various pieces of UI could look like with it.

### [AG-UI + Ragas for Evals](https://sf.aitinkerers.org/talks/rsvp_ka1abEJdLQY)

There are numerous examples in the Ragas documentation and Github showing how to integrate directly with various agentic frameworks, but they all involve directly invoking the agents through their respective APIs. This demo will show how AG-UI can be used as a more generic integration mechanism, communicating with any AG-UI-compatible agent over HTTP instead, opening up additional frameworks (e.g., ADK) as well as test scenarios (e.g., easily running the same datasets across a wider variety of agents).
