It was all about AI agents at Microsoft's Build developer conference, with OpenAI CEO Sam Altman joining to talk about the future of AI coding.

GitHub has launched a powerful AI coding agent in Copilot that writes code, fixes bugs, and opens pull requests.

Microsoft integrates the Model Context Protocol into Windows 11, paving the way for secure, AI-driven agents to interact with apps and system tools.

This is another example of Microsoft's "agentic" approach to AI, as Discovery is intended to let researchers create virtual teams of AI agents that can be instructed with specific data and guidelines to function as, for example, a "molecular properties simulation specialist" that can then assist with R&D and learn over time.

Microsoft said on Monday it would offer new AI models made by Elon Musk's xAI, Meta Platforms and European startups Mistral and Black Forest Labs hosted in its own data centers, and unveiled a new artificial-intelligence tool designed to complete software coding tasks on its own.

Microsoft started off the event by introducing a number of AI-powered features designed to enhance the software development experience.

AI agents will increasingly impact APIs and applications—adding complexity and autonomy and creating unique security challenges.

Microsoft introduces Windows AI Foundry to help developers build and run AI models directly on PCs, part of a broader push to bring AI to the device.
