Same mission, new chapter. Building the foundation for human + agent collaboration. CVP at Microsoft, M365 Core + Work IQ. // ☁️🌈

[Amanda Silver @amandaksilver]

Could an AI describe your work life without you telling it anything? I've been at Microsoft 24 years and couldn't do it on a napkin. Work IQ did it in 2 minutes.

For a little fun at our LT offsite, we each ran a simple prompt through M365 Copilot with Work IQ. It looked through our documents, meetings, org graph, and public LinkedIn and GitHub profiles... and drew this👇

This is the line between a chatbot and an agent that genuinely gets you. That's Work IQ: the enterprise intelligence layer that lets agents reason and act with your organization's context. Now GA.

Huge news. Anthropic models now GA in Foundry.

[Microsoft Azure @Azure]

Claude in Microsoft Foundry is now generally available, hosted on Azure. Prompt caching and extended thinking are supported today, with more capabilities on the way.

The real question about AI agents isn't how fast they answer... it's whether we can trust them with the work.

So we asked 300 engineers to rank their confidence across 101 tasks. The 2026 Agent Confidence Index, with @techreview, is live:

This finally answers the question… Horse sized ducks, definitely.

@headinthebox Sorry to disappoint. It wasn't in the context window. ;-)

AI at work will be built by developers—and adopted by businesses that trust agents to reason, act, and stay grounded in organizational context.

With Work IQ APIs now GA, teams build on the same intelligence layer behind Microsoft 365 Copilot.

Let’s build!

Open source at Microsoft didn’t happen overnight. @amandaksilver walks through the journey from early steps with jQuery to open-sourcing #TypeScript, Chakra, #dotNET and #VSCode, and the culture shift behind it.

1 million context window and configurable reasoning levels are now available in GitHub Copilot for @code, Copilot CLI, and Copilot app developers.

I'm incredibly excited about ACA Sandboxes which bring microVMs, subsecond starts, strong isolation, connectors (m365, teams, Kusto, databases, queues!)!, secure egress, and scale. Check it out and let us know how you plan to use it.

I’ve been excited about many of the things we’ve shipped over the last year, across GitHub Copilot CLI, SDK, Cloud Agents, and more.

But I am even more excited about what we’re delivering now with the GitHub Copilot App.

This is the app that I use all day every day now.

It is, I believe, an ideal experience for anyone working on and around software engineering projects and wanting to work in the most agent-native way possible today.

Great to be back at Microsoft Build today. For us, it is not about any one piece of technology or even the platform.

It is about how we can build a frontier intelligence ecosystem together.

Sharing some of our big announcements today ...

[Microsoft Azure @Azure]

Stop stitching vendors together to run open models in production. Fireworks AI on Microsoft Foundry is GA. One endpoint. Enterprise SLAs. Zero setup.

@kdaigle breaks down all the news from #MSBuild in this monster post: https://t.co/UX50VTo7v9

[Kyle Daigle @kdaigle]

@github @MicrosoftAI The pattern across Build: agents need a stack.

Developer surface. Model choice. Local compute. Sandboxing. Enterprise context. Tuned models. That’s the difference between “agent demo” and “agent platform.”

Introducing Microsoft Scout, the first autopilot agent from Microsoft - 57 days after starting my new job, we are launching Microsoft Scout to our Frontier customers. Big day for the team and for @openclaw #MicrosoftBuild https://t.co/ZGl47ADnCg

[Amanda Silver @amandaksilver]

As #AI shifts from tools to agents, the real unlock will be organizational context.

With Work IQ APIs, developers can now build agents that understand how work actually gets done—across people, content, and workflows—and act on it. Read the #MSBuild announce: Announcing the new Work IQ APIs | Microsoft 365 Blog

Why didn’t Script# stick and what led to #TypeScript instead? @amandaksilver explains how aligning with the JavaScript runtime and the open web ecosystem became essential for building at scale.
