The rise of AI agents will reshape how intelligent systems are being built. According to a recent PagerDuty survey , over half of companies are already deploying “agentic AI” solutions, and by 2027, as many as 86% expect to be operational with AI agents. Organizations see a high upside: 62% of leaders expect triple-digit ROI from agentic AI, often by automating 26–50% of workloads . But building effective agents requires more than just powerful models—it demands smart orchestration of memory, tools, prompts, and actions to make AI truly useful.
Two frameworks have emerged as leading contenders in this space: LangChain and AutoGen. While both are open-source and designed to streamline large language model (LLM) applications, they take fundamentally different approaches to solving the same problem—how to make AI agents smarter, faster, and more autonomous.
So, which one should you choose?
Choosing the right agent framework could save weeks of development and boost model efficiency. In this blog, we break down the core differences between AutoGen and LangChain to help you make the right call.
