I had the pleasure of getting to chat with @jimcramer this week to discuss Microsoft’s vision for security and how we hope to secure future generations with the help of our generative AI. Thank you, Jim. It was an honor to join you on @MadMoneyOnCNBC ! 💜 cnbc.com/2023/11/27/microsof…

Will @vasujakkal and I accidentally match outfits again this year at #MSIgnite?! Better get yourself to SF to find out (or maybe just come for the tech and announcements!)

Starting today, Azure AI Foundry is rolling out new multimodal models from OpenAI: GPT-Image-1-mini, GPT-realtime-mini, and GPT-audio-mini, plus major GPT-5 upgrades (including GPT-5-Pro). This joins the Microsoft Agent Framework, enabling customers to build agents across multiple modes in one secure integrated ecosystem. 🔗 Learn more: msft.it/6014sICXu

In an interview with Kyle Alspach, @vasujakkal, @Microsoft’s corporate VP for security, compliance, identity, management and privacy, says the introduction of Sentinel data lake and other new capabilities aims to make it much more than a SIEM offering: okt.to/GrA59j

If intelligence is the log of compute… it starts with a lot of compute! And that’s why we’re scaling our GPU fleet faster than anyone else. Just last year, we added over 2 gigawatts of new capacity – roughly the output of 2 nuclear power plants. And today we’re going further, announcing the world's most powerful AI datacenter, located in southeastern Wisconsin. Fairwater is a seamless cluster of hundreds of thousands of NVIDIA GB200s, connected by enough fiber to circle the Earth 4.5 times. It will deliver 10x the performance of the world’s fastest supercomputer today, enabling AI training and inference workloads at a level never before seen. For AI training workloads, you need compute at exponential scale. That’s why we designed the datacenter, GPU fleet, and network together as one integrated system. This ensures a single job can run from day 1 at exponential scale across thousands of GPUs. Fairwater uses a liquid-cooled closed-loop system for cooling GPUs that requires zero water for operations after construction. And we’re matching all of the energy that is consumed with renewable sources. And of course, it is just one of several similar sites we’re lighting up across our 70+ regions. We have multiple identical Fairwater datacenters under construction in other locations across the US, in addition to our AI infrastructure already deployed in over 100 datacenters around the world, powering model training, test-time compute, RL tuning, and real-time inference at global scale. Too often during times like this, people go with the current and only later wonder, how did we get here? With Fairwater, we're charting a new path: doing the hard engineering work, bringing compute, network, and storage into one highly scaled cluster, and designing closed-loop energy systems to meet real-world computing needs. And partnering with local communities to ensure it's thoughtfully done in a way that is sustainable, creates new jobs, and expands opportunity. We are thrilled to see this take hold in Wisconsin, and we are just getting started.

We’re committed to creating new opportunity for people and businesses on both sides of the Atlantic, and ensuring America remains a trusted and reliable tech partner for the United Kingdom. That’s why today we announced a $30 billion investment in the UK over four years, including building the country's largest supercomputer with over 23,000 of the world’s most advanced GPUs, to expand the digital infrastructure that will bring our two nations even closer together.

For more than four decades, Microsoft has partnered with the U.S. Government to serve the American people. From modernizing IT infrastructure to advancing cybersecurity, our partnership has always been rooted in trust, innovation, and shared purpose. Today, we are building on that legacy with a new agreement with the U.S. General Services Administration — including a no-cost Microsoft 365 Copilot offer — to accelerate the adoption of AI and digital technologies across federal agencies and deliver more than $3 billion in total savings to taxpayers in the first year alone. This collaboration is about empowering public servants with the tools they need to deliver on their missions more effectively and securely. By bringing the latest advances in cloud and AI — including Azure, Microsoft 365 Copilot, Dynamics 365, and our security platforms — backed by industry-leading security and compliance certifications, we aim to help agencies modernize systems, improve citizen services, and advance their technology transformation goals.

True AI transformation starts with security. 🚀🔒 @VasuJakkal previews #MSIgnite, where we’ll explore how agentic AI is shaping a future built on secure, responsible innovation. Register today: msft.it/6011sk5AH

We just wrapped our earnings call. It was a very strong close to our fiscal year. A few highlights:

In response to concerns raised earlier this week about US-supervised foreign engineers, Microsoft has made changes to our support for US Government customers to assure that no China-based engineering teams are providing technical assistance for DoD Government cloud and related services. We remain committed to providing the most secure services possible to the US government, including working with our national security partners to evaluate and adjust our security protocols as needed.

We kicked off @RSAConference with our 4th annual Microsoft Pre-Day event featuring keynotes from Security leaders Charlie Bell & @vasujakkal. Excited to connect with customers, partners, and analysts this week at #RSAC to share the latest on our security innovations.
