Fully managed enterprise platform for building, deploying, and scaling AI agents with advanced multi-agent orchestration, enterprise security, and Azure ecosystem integration
Microsoft Foundry Agent Service is a fully managed enterprise AI agent platform in the Azure ecosystem, offering pay-per-use pricing for building, deploying, and orchestrating intelligent agents at scale. The platform addresses the growing need for sophisticated AI agent deployment in business environments by providing a comprehensive three-tier agent architecture that scales from no-code prototypes to fully custom containerized deployments. Prompt agents enable rapid prototyping through a portal-based no-code interface, workflow agents add declarative multi-step orchestration with branching and human-in-the-loop capabilities, and hosted agents allow teams to deploy custom code built with frameworks like LangGraph, Semantic Kernel, or AutoGen on managed infrastructure.
At the core of the platform is access to over 11,000 foundation models from the Foundry model catalog, including GPT-4o, Llama, Mistral, DeepSeek, and specialized industry models. Agents can intelligently route between models based on task requirements, and switching models is a configuration change rather than a code rewrite. Built-in tools cover web search via Bing, file search, Azure AI Search integration, code interpretation, and persistent memory, while enterprise connectors provide access to SharePoint, Microsoft Fabric, Azure Functions, and Logic Apps.
