2024 was a significant year for the development and deployment of agents, which are highly controllable, narrowly scoped, and custom-cognitive-architecture-based. The launch of LangGraph in early 2024 marked a new take on an agentic framework, providing a low-level, controllable architecture that has become the go-to default framework for agents. Companies such as Uber, AppFolio, LinkedIn, Elastic, and Replit have successfully built agents using LangGraph, sharing their lessons learned through various forms of storytelling. These stories highlight the importance of human-in-the-loop approaches and multi-agent setups in building effective agents. The adoption of LangGraph has enabled these companies to tackle complex tasks such as large-scale code migrations, conversational interfaces, and data access, showcasing its potential in various industries.
