Microsoft Foundry unifies agents, models, and tools under a single management grouping with built-in enterprise-readiness capabilities including tracing, monitoring, evaluations, and customizable enterprise setup configurations. The platform provides streamlined management through unified role-based access control (RBAC), networking, and policies under one Azure resource provider namespace.
Tip
- Coming from Azure OpenAI? Upgrade your Azure OpenAI resource to a Foundry resource while preserving your endpoint, API keys, and existing state.
- Using hub-based projects? Hub-based projects are accessible in the Foundry (classic) portal. New investments are focused on Foundry projects in the new portal.
Get started
Build your first agent in minutes, or open the portal to explore models and tools.

What you can build
| Capability | Description |
|---|---|
| Agents | Build declarative prompt agents in the portal or SDK, or deploy hosted agents that run your own code. Learn more in Foundry Agent Service. |
| Models | Access more than 1,900 models from Microsoft, OpenAI, Anthropic, Meta, and others. Browse the Foundry Models catalog. |
| Tools and knowledge | Extend agents with built-in tools, memory, and retrieval from the tool catalog. |
Enterprise-ready platform
Foundry brings production capabilities to every project:
- Observability: Trace, monitor, and evaluate agents and models with built-in dashboards. See Observability.
- Governance and security: Apply Microsoft Entra identity, role-based access control, content filters, network isolation, and Azure Policy. See the Foundry control plane.
- One management plane: Manage agents, models, and tools as a single Azure resource with unified access control, networking, and policies.
Evolution of Foundry
Foundry consolidates several previous Azure AI services and tools into a unified platform. The following table maps previous concepts to their current equivalents. For detailed guidance on transitioning, see Navigate from classic to the new experience.
| Dimension | Previous | Current |
|---|---|---|
| Brand | Azure AI Studio / Azure AI Foundry | Microsoft Foundry |
| Brand | Azure AI Services | Foundry Tools |
| Portal | Foundry (classic) | Foundry |
| Agent API | Assistants API (Agents v0.5/v1) | Responses API (Agents v2) |
| API versioning | Monthly api-version params |
v1 stable routes (/openai/v1/) |
| Resource model | Hub + Azure OpenAI + Azure AI Services | Foundry resource (single, with projects) |
| SDKs & endpoints | Multiple packages (azure-ai-inference, azure-ai-generative, azure-ai-ml, AzureOpenAI()) against 5+ endpoints |
Unified project client (azure-ai-projects 2.x) + OpenAI() against one project endpoint. |
| Terminology | Threads, Messages, Runs, Assistants | Conversations, Items, Responses, Agent Versions |
