AutoGen vs Vercel AI SDK (2026)
Updated March 10, 2026
Overview
AutoGen is Microsoft's open-source framework for building multi-agent AI systems. It enables the creation of conversational agents that can work together, use tools, and interact with humans to solve complex tasks. AutoGen supports customizable agent behaviors, flexible conversation patterns, and integrations with various LLMs. The framework is popular for building research assistants, coding agents, and automated analysis pipelines.
The Vercel AI SDK is a TypeScript toolkit for building AI-powered web applications with React, Next.js, and other frameworks. It provides streaming UI components, structured generation, tool calling, and multi-step agent workflows. The SDK supports all major LLM providers through a unified interface and is the most popular choice for frontend developers building AI features into web applications.
