AG-UI
Universal translator for AI-driven systems, enabling fluent agent-user communication.
AG-UI Overview
AG-UI standardizes how front-end applications connect to AI agents through an open protocol, acting as a universal translator for AI-driven systems. It enables developers to build next-generation AI workflows requiring real-time interactivity, live state streaming, and human-in-the-loop collaboration. The protocol provides a straightforward approach to integrating AI agents with front-end frameworks like CopilotKit, offering building blocks for efficient wire protocols and best practices for chat, streaming state updates, and shared state. AG-UI is designed for developers and enterprises looking to enhance AI agent interactions in their applications.

AG-UI Core Features
Universal Translator for AI Agents
AG-UI acts as a universal translator, ensuring seamless communication between front-end applications and AI agents, regardless of the agent's native language or framework.
Real-Time Interactivity
Supports real-time interactivity between users and AI agents, enabling dynamic and responsive AI-driven applications.
Live State Streaming
Facilitates live state streaming, allowing continuous updates and synchronization between the front-end and AI agents.
Human-in-the-Loop Collaboration
Enables human-in-the-loop workflows, where users can interact with and guide AI agents during execution.
Flexible Event-Driven Communication
Uses an event-driven communication model with 16 standardized event types, making it adaptable to various agent frameworks.
Bidirectional Interaction
Supports bidirectional interaction, allowing agents to accept input from users and vice versa.
Transport Agnostic
Does not mandate specific transport mechanisms, supporting SSE, webhooks, WebSockets, and more.
Existing Integrations
Integrated with popular agent frameworks like LangGraph, CrewAI Flows, CrewAI Crews, Mastra, and AG2 for easy adoption.
AG-UI Use Cases
AI-Powered Chat Applications
AG-UI enables seamless integration of AI agents into chat applications, providing real-time responses and state updates.
Collaborative Workflows
Facilitates collaborative workflows where humans and AI agents work together, such as in content creation or decision-making processes.
Dynamic Dashboard Updates
Supports live state streaming for dashboards, ensuring continuous updates from AI agents to the front-end.
How to Use AG-UI
Choose your preferred agent framework (e.g., LangGraph, CrewAI) and ensure it is compatible with AG-UI.
Integrate AG-UI middleware connectors or implement AG-UI compatible servers using TypeScript or Python.
Configure the AG-UI protocol to handle event-driven communication between your front-end and AI agents.
Set up bidirectional interaction channels to enable human-in-the-loop workflows.
Deploy your application and monitor the real-time interactivity and state streaming between users and agents.
