AutoGen is the original open-source multi-agent framework from Microsoft Research, focused on flexible agent conversations and research-driven innovation. In 2026, Microsoft announced that AutoGen and Semantic Kernel would enter maintenance mode, with new development consolidating into the Microsoft Agent Framework. This new framework combines AutoGen's simple multi-agent abstractions with Semantic Kernel's enterprise-grade features including session-based state management, filters, telemetry, and broad model support. Existing AutoGen users are encouraged to evaluate the Microsoft Agent Framework for new projects, while AutoGen will continue to receive critical bug fixes and security patches during its maintenance period.
Yes, AutoGen is fully open-source under the MIT license, which permits unrestricted commercial use, modification, and distribution without licensing fees or usage limits. There are no per-API-call charges from AutoGen itself, though you will incur costs from the underlying LLM providers (such as OpenAI or Azure OpenAI) that power your agents. Enterprise teams seeking managed hosting can use Azure AI Foundry integration, which carries its own Azure compute and service pricing, but the framework itself remains completely free. This makes AutoGen highly accessible for startups and enterprises alike, with total cost driven primarily by LLM API usage volume and any optional cloud infrastructure.
AutoGen provides sandboxed code execution environments using Docker containerization for running Python and shell scripts generated by agents. This isolation prevents agent-generated code from accessing the host system's files, network, or resources outside the container. Developers can configure execution policies, set resource limits, and control which packages are available within the sandbox. For local development, a local command-line executor is also available, though Docker-based execution is strongly recommended for any shared or production environment. Additionally, Azure Container Apps can be used for managed sandboxed execution with enterprise-grade security controls, network isolation, and compliance certifications.
Yes, AutoGen supports multiple LLM providers through its modular architecture. You can use OpenAI, Azure OpenAI, and any OpenAI-compatible API endpoint, which covers providers like Anthropic (via proxy), local models through Ollama or LM Studio, and other hosted services. The Extensions API allows developers to build custom model clients for providers not natively supported. This flexibility lets teams choose models based on cost, performance, privacy requirements, or specialized capabilities for different agents within the same system, optimizing each agent's LLM selection for its specific role and task requirements.
AutoGen Studio is a no-code graphical interface for building and testing multi-agent workflows through drag-and-drop configuration. It is useful for rapid prototyping, learning multi-agent concepts, and demonstrating agent capabilities to stakeholders. However, Microsoft explicitly states that AutoGen Studio is a research prototype not intended for production deployment—it lacks enterprise security features, authentication mechanisms, and has not undergone rigorous security testing. For production systems, use the AutoGen SDK directly with proper security configurations, Docker-based sandboxing, and deploy via Azure AI Foundry or your own hardened infrastructure with appropriate access controls and monitoring.
AI builders and operators use Microsoft AutoGen to streamline their workflow.
