Hey, this is Lance. I want to talk a bit about the deep agents package that we recently released. Now, the length of tasks that an agent can take every seven months.And we see numerous examples of popular longrunning agents like Claude Code, Deep Research, Manis. The average Manis task, for example, can be up to 50 different tool calls. And so, it's increasingly clear that agents are needed to do what we might consider deeper work or more challenging tasks that take longer periods of time.Hence, this term d ...

Agent Protocol Landscape - The industry is moving towards interoperability through three open protocols for agentic frameworks [1] - These protocols create a universal language for agents, enabling different frameworks to work together [3] Key Protocols - AG-UI (Agent-User Interaction) facilitates bidirectional communication between agent backends and frontends, enabling interactive agent experiences within applications [1][2] - A2A (Agent-to-Agent) is a protocol for multi-agent coordination, task delegation, and intent sharing across systems [3][5] - MCP (Model Context Protocol) is the standard for agents connecting to tools, data, and workflows [5] Interoperability and Integration - Protocols eliminate the need for point-to-point integrations, allowing developers to build to protocols instead [3] - Frameworks like LangGraph, CrewAI, and Agno can be integrated into the same frontend without rewriting UI logic [3] - CopilotKit unifies the entire stack into one framework, simplifying the implementation of these protocols [4] Example Workflow - A LangGraph agent retrieves data via MCP, delegates analysis to a CrewAI agent via A2A, and streams results to a React app via AG-UI [6]

Agent Protocol Landscape - The industry is converging on three open protocols for agent interoperability: AG-UI (Agent-User Interaction), MCP (Model Context Protocol), and A2A (Agent-to-Agent) [1][2] - These protocols are complementary layers of a stack, not competing standards, facilitating a universal language for agents [2] - Protocols enable integration of frameworks like LangGraph, CrewAI, and Agno into the same frontend without rewriting UI logic [3] Protocol Functionality - AG-UI enables bidirectional connection between agentic backends and frontends, creating interactive agents within applications [1][2] - MCP standardizes how agents connect to tools, data, and workflows [2] - A2A facilitates multi-agent coordination, enabling task delegation and intent sharing across systems [2][5] Framework Integration - CopilotKit unifies the entire protocol stack into one framework, providing generative UI support and production-ready infrastructure [3][4] - An example workflow involves a LangGraph agent pulling data via MCP, delegating analysis to a CrewAI agent via A2A, and streaming results to a React app via AG-UI [6] Development Focus - Protocols allow developers to focus on building agent capabilities instead of integration mechanics, as interoperability is handled automatically [3]

Hi there, this is Christian from Langchain. Just a couple of weeks ago, we released version one of Langchain and Lang Graph. And one of the cool features of it is that it makes it really easy to stream events and results from the agent down to any type of front end that you're using, whether it's React, Vue, or Swelt.So, in this video, I want to build a little CHPT clone that shows you how you can build and create agent right in your Nex. js application. Every longchain agent maintains a state throughout it ...
