Connect LangChain Deep Agents to a Live Frontend with CopilotKit

Description

Bring any frontend to your LangChain Deep Agents! LangChain's Deep Agents plan, research, and write files - but it all happens on the backend where you can't see it. In this video, we connect a Deep Agent to a live frontend using CopilotKit, so you can actually watch the whole process happen in real time. We'll cover the architecture (how the FastAPI backend, Next.js frontend, and CopilotKit work together), show a live demo of the research workflow, and walk through setting it up and running it locally step by step. 🔗 Links: GitHub Repo: https://github.com/CopilotKit/deep-agents-demo Deep Agents Docs: https://docs.copilotkit.ai/langgraph/deep-agents CopilotKit Docs: https://docs.copilotkit.ai Blog Post: https://www.copilotkit.ai/blog/how-to-build-a-frontend-for-langchain-deep-agents-with-copilotkit LangChain docs: https://docs.langchain.com/oss/python/deepagents/overview You'll need 2 API keys OpenAI: https://platform.openai.com/api-keys Tavily: https://app.tavily.com/home
