Microsoft Foundry

Microsoft Foundry is Microsoft's managed model + agent platform on Azure — model catalogue, Agent Service, evaluations, observability, and a portal that wraps it all. Renamed twice — Azure AI Studio (preview, 2023–2024) → Azure AI Foundry (GA, Ignite Nov 2024) → Microsoft Foundry (late 2025, “Azure AI” prefix dropped; the azure-ai-projects SDK adopted the new brand in November 2025) — with a flatter resource model that replaced the prior Hub-and-Project split. The portal at ai.azure.com and the docs path /azure/ai-foundry/ survived every rename. Pages below are sourced from learn.microsoft.com/azure/ai-foundry.
