Azure AI Foundry

This year, at Microsoft Build, we introduced new AI tools and capabilities designed to empower every software developer to become an AI developer.

To help these AI agents become even more powerful and handle more complex tasks, they need state-of-the-art models, integrated tools, and built-in governance. At Microsoft Build 2025, we’re unveiling 10 innovations in Azure AI Foundry to make this possible.

Agentic DevOps is the next evolution in the software development lifecycle. Read how these AI agents help developers accelerate delivery and stay focused on high-impact work while remaining in control of the process.

In this blog, I’ll cover the latest slate of announcements across Microsoft Fabric and the entire Azure Data portfolio, designed to empower every developer on the planet to do more with data.

We have architected Microsoft Discovery to be highly extensible, enabling researchers to integrate the latest Microsoft innovations with their own models, tools, and datasets as well as a wide range of partner and open-source solutions.

Today, we’re excited to announce two major enhancements to model fine-tuning in Azure AI Foundry—Reinforcement Fine-Tuning (RFT) with o4-mini, coming soon, and Supervised Fine-Tuning (SFT) for the 4.1-nano model, available now.

Agent2Agent can enable structured agent communication—exchanging goals, managing state, invoking actions, and returning results securely and observably. Developers can use tools they know, like Semantic Kernel or LangChain, and still interoperate.

Microsoft continues to add to the conversation by unveiling its newest models, Phi-4-reasoning, Phi-4-reasoning-plus, and Phi-4-mini-reasoning.

Azure AI Foundry is like GPS for your AI ambitions: it simplifies navigating the insane pace of innovation in the AI landscape so you see where you are today, evaluate what’s new, and plan, execute, and manage your growing AI portfolio.

We are thrilled to announce the launch of GPT-image-1, the latest and most advanced image generation model, now available on Microsoft Azure OpenAI Service.

We are thrilled to announce the availability of the latest iterations in the o* reasoning series: o3 and o4-mini models on the Microsoft Azure OpenAI Service.

We are excited to share the launch of the next generation of the GPT-4o model series with GPT-4.1, 4.1-mini, and 4.1-nano to Microsoft Azure OpenAI Service.
