Hi everyone, it's Sean, so today I wanna show you how to design and launch an AI deep research agent like a pro.

You Can Learn Deep Research AI Agent Design & Launch In 25 Min | LangChain, OpenSource I'm Open Sourcing a Deep Research AI Agent System Design and Full Stack Codebase I built. This video shows you how I test Kimi K2 0905, Claude-4, GPT-5 on this end-to-end system of Deep Research, and export the research report to Google Docs. This isn't a mockup. It's a real functional product with a deep dive into its workflow. My public repos are built on top of the LangChain Open Deep Research functionalities, and introduced a streaming process to show the NextJS frontend how the FastAPI Python backend streams Deep Research steps hosted on Google Cloud (GCP). You can build anything. You can learn anything. 💪
