+| Feature | Description | Key Benefits |
+|---------|-------------|--------------|
+| [Hosted Agents](https://learn.microsoft.com/en-us/azure/ai-foundry/agents/concepts/hosted-agents?view=foundry&tabs=cli) | Build, test, and deploy agents without managing infrastructure. No need for Kubernetes or containers. Supports multi-agent orchestration with shared memory and tools. | Simplifies deployment, reduces infra overhead, enables complex agent ecosystems for enterprise workflows and internal copilots. |
+| [Model Router](https://learn.microsoft.com/en-us/azure/ai-foundry/openai/concepts/model-router?view=foundry-classic#supported-underlying-models) | Routes requests across multiple models (OpenAI, Claude, Gemini, etc.). Automatically selects the best model for the task. Supports fallback and load balancing. | Optimizes performance and cost, ensures reliability, allows seamless switching between models without code changes. |
+| [BYO Model Gateway](https://learn.microsoft.com/en-us/azure/ai-foundry/agents/how-to/ai-gateway?view=foundry) | Bring your own model (BYOM) from Hugging Face, Azure ML, or custom endpoints. Integrates with Foundry’s governance and observability stack. | Flexibility to use custom or proprietary models, hybrid cloud/on-prem strategies, unified monitoring and compliance. |
+| [One-Click Deployment to Microsoft 365](https://learn.microsoft.com/en-us/azure/ai-foundry/agents/how-to/publish-copilot?view=foundry) | Deploy agents directly into Teams, Outlook, SharePoint, and other M365 apps. Includes low-code/no-code templates for internal copilots. Supports user identity, permissions, and organizational data access. | Rapid enterprise adoption, seamless integration with daily productivity tools, secure identity-aware deployments. |
+| [Built-in Observability](https://techcommunity.microsoft.com/blog/azure-ai-foundry-blog/observability-in-foundry-control-plane-empowering-developers-to-evaluate-and-opt/4471107) | Native tracing, telemetry, and evaluation dashboards. Human-in-the-loop feedback tools. Agent memory inspection and optimization tracking. | Improves reliability, enables debugging and optimization, ensures agents meet performance and compliance standards.

+| [Enterprise Governance](https://learn.microsoft.com/en-us/azure/ai-foundry/control-plane/overview?view=foundry) | Identity management via Microsoft Entra ID. Policy enforcement, audit logging, and compliance controls. Role-based access and agent sandboxing. | Enterprise-grade security, compliance readiness, controlled access, and safe scaling across organizations. |
