AutoGen vs OpenAI AgentKit
A side-by-side comparison of capabilities, autonomy, integrations, and pricing to help you choose.
Short answer: choose AutoGen if you want microsoft framework for multi-agent conversational ai applications (Supervised agent, free); choose OpenAI AgentKit if you want openai's toolkit to build, deploy, and optimize agents from prototype to production (Supervised agent, usage).

AutoGen
- +Strong, well-known abstraction for multi-agent conversation (two-agent and group-chat patterns) from Microsoft Research
- +v0.4 rewrite brings an asynchronous, event-driven architecture with better observability and control
- +Open source, model-agnostic, and supports humans as first-class participants in agent conversations
- -Framework, not a product: autonomy and reliability depend entirely on what the developer builds
- -Now community-managed and described as in maintenance mode, with the original team's active work continuing under the renamed AG2 project
OpenAI AgentKit
- +Lowers the barrier to production agents with a visual builder, embeddable chat UI, connectors, evals, and guardrails in one stack
- +Native to OpenAI's API ecosystem with MCP and prebuilt enterprise connectors, plus code export to the Agents SDK
- +ChatKit and Guardrails are open-source
- -Major lifecycle risk: Agent Builder and Evals are being deprecated (shutdown November 30, 2026) about a year after launch
- -Usage-based pricing makes total cost hard to predict for heavy multi-step agents
Which should you choose?
AutoGen is microsoft framework for multi-agent conversational ai applications, best for developers, enterprise. OpenAI AgentKit is openai's toolkit to build, deploy, and optimize agents from prototype to production, best for developers, mid-market, enterprise. The right choice depends on the autonomy level you want, your existing integrations, and your budget, all compared above.
