Harrison Chase discusses the evolution of agent building, highlighting the transition from early AI frameworks to more advanced tools like LangGraph, Google ADK, and Vercel’s AI SDK, which gave developers greater control over LLMs. These tools enabled the creation of complex AI applications, with models becoming powerful enough to power agents in 2025. Managed agent experiences, such as Deep Agents, simplify the development process by bundling the harness with infrastructure, focusing on business logic, runtime reliability, and user experience. The launch of Managed Deep Agents aims to make agent development more accessible and efficient, offering configurability and production-ready infrastructure with features like LangSmith Deployments and sandboxes.
