Future of Azure AI Agent Service

[mollaosmanoglu]

Hi, since OpenAI created Responses API, and Azure AI Agent service is built on top of Assistants API, I am wondering if Microsoft is working in the background to bridge this gap (to migrate the Agent service to Responses API as a foundation layer), can anyone help me with this? I am contemplating if I should migrate to Azure Responses API or stay on Azure AI Agent service.

Good question and one that a lot of people building on Azure AI Agent Service are thinking about right now.

From what is publicly known, Microsoft has not officially announced a migration of Azure AI Agent Service from the Assistants API foundation to the Responses API. However, the direction of travel is fairly clear. The Responses API is OpenAI's newer, more flexible foundation that supports built-in tools, multi-turn state management, and a cleaner architecture compared to the Assistants API. It would make sense for Microsoft to align Azure AI Agent Service with that foundation over time, but there has been no official roadmap statement on this yet.

On your actual decision of whether to migrate to Azure Responses API or stay on Azure AI Agent Service, here is how I would think about it. If your current implementation is stable and in production, staying on Azure AI Agent Service is the lower risk option for now. The service is supported and Microsoft has not indicated it is being deprecated. If you are starting something new or doing a significant refactor, building on the Responses API gives you a more future-proof foundation and closer alignment with where OpenAI's ecosystem is heading.

The practical differences worth knowing: the Responses API gives you more granular control over tool calls and state, while Azure AI Agent Service abstracts a lot of that away and adds enterprise features like Azure RBAC, managed identity support, and tighter integration with Azure AI Studio. If those enterprise controls matter for your use case, Agent Service still has advantages even on the older foundation.

Worth keeping an eye on the Azure AI Agent Service GitHub repo and Microsoft's AI blog for any migration announcements. This is a fast moving space.
