Microsoft held its annual Build conference on May 19, unveiling a set of updates focused on AI agents, software development and scientific research.
Microsoft Chairman and CEO Satya Nadella opened the event by outlining the company’s vision for an open "agentic web," in which AI agents interact, decide and execute tasks on behalf of users and organizations.
"We are reshaping each layer of the stack to help every developer build applications and agents that serve teams and companies," Nadella said in a post on X.
One highlight was GitHub Copilot’s new coding agent. Integrated into GitHub and Visual Studio Code, the agent can be assigned tasks through GitHub issues or Copilot Chat. It then spins up a secure session via GitHub Actions, analyzes code, and submits changes as draft pull requests. Tasks include bug fixes, feature work, refactoring and documentation updates. The agent logs its actions for review and requires human approval before merging.
Microsoft also introduced Microsoft 365 Copilot Tuning in Copilot Studio, a low–code feature that allows enterprises to adapt AI models to their own workflows and data. Legal, finance and other teams can now create specialized agents that reflect firm-specific language and processes without writing code. All data remains inside Microsoft 365’s secure boundary.
Another addition, multi-agent orchestration, lets several agents collaborate on cross–departmental workflows. For example, IT, human resources and marketing agents can coordinate steps in an employee onboarding process.
Azure AI Foundry received key enhancements, including support for over 10,000 models from third–party and open–source providers. Developers can choose and fine–tune models such as Grok 3 and Grok 3 Mini. New services include agentic retrieval in Azure AI Search and a Foundry Agent Service for automating complex workflows.
The conference also saw the launch of NLWeb, an open–source framework that adds natural language interfaces to websites. Websites can expose content using Schema.org or RSS and allow users to query pages via a chat interface powered by custom AI models.
Microsoft Discovery, a platform for scientific research, uses AI agents to generate hypotheses, run simulations and analyze results. Nadella pointed to a project identifying a coolant candidate free of so–called “forever chemicals.”
These announcements highlight Microsoft’s push to integrate AI agents across development, business and research tasks. Build attendees will now test tools designed to simplify coding, customize AI for enterprise needs and accelerate scientific discovery.
