Microsoft Build
Build is Microsoft’s main developer event for the year, and it’s typically where the company unveils its latest Windows road map alongside additions to Office, Azure, and many other software and services. At Build 2026, we’re expecting a lot of news on Copilot and Microsoft’s other AI initiatives.




That’s a wrap for the first Build keynote. We’re off to listen in to sessions and learn more about Microsoft’s big AI plans for 2024. Stay tuned for a lot more on that, soon.
It’s clear OpenAI Sam Altman isn’t at Microsoft Build to announce a new model, but he’s happy to tease that the next big one is on the way. Microsoft built an even bigger supercomputer for this work, and now Altman hints that new modalities and overall intelligence will be key to OpenAI’s next model. “The most important thing and it sounds like the most boring thing I can say... the models are just going to get smarter, generally across the board,” says Altman.
OpenAI CEO Sam Altman has just stepped onstage at Microsoft Build. He’s having a conversation with Microsoft CTO Kevin Scott about what’s next for OpenAI and Microsoft’s big supercomputer plans.
Sal Khan, CEO of Khan Academy, is up onstage at Microsoft Build to talk about the nonprofit’s use of AI in education. Microsoft is partnering with the Khan Academy for AI-powered tutoring tools that will be free for all US educators as of today.
“It’s 12x cheaper to make a call to GPT-4o than the original model,” says Microsoft CTO and EVP of AI Kevin Scott. “It’s also 6x faster in time to open response.” These speed increases and cost decreases are super important for OpenAI’s latest model, but things aren’t going to slow down. Things will get cheaper and more robust over time, says Scott.
“We’re riding an extraordinary platform wave,” says Microsoft CTO and EVP of AI Kevin Scott onstage at Build. He likens it to the PC evolution and Moore’s Law or even broadband internet. Microsoft has been contributing to this with the company’s Copilot stack, which has helped the company build AI products quickly. “We are nowhere near... how powerful we can make AI models,” says Scott.


That’s what Microsoft CTO and EVP of AI Kevin Scott said last year at Build, just as the company was unveiling its AI tools. “I want to thank you all for the great shit that you’ve made over the past year,” says Scott, as he steps onstage at Build 2024.
Microsoft’s Windows chief, Pavan Davuluri, is discussing the company’s new push to get developers to build AI apps on Windows. He argues Windows is the most open platform for AI, just hours after announcing a new Windows Copilot Runtime that sets the stage for the next decade of Windows app development.
Pavan Davuluri had a busy day announcing new Arm-based Surface devices yesterday and a big push to bring more AI-powered experiences and apps to Windows. The Windows and Surface chief is now onstage at Microsoft Build to discuss Microsoft’s Copilot Plus PCs and Windows AI.
Microsoft is making some improvements to Teams aimed at developers. You can now paste source code inside Teams with syntax formatting. There’s even co-editing with Loop, better keyboard shortcuts, and custom emoji.
Microsoft’s Jeff Teper, head of collab apps and platforms, is walking the Build audience through the company’s new Copilot connectors and extensions. They’re designed for businesses to extend the AI assistant to their line of business apps and add data from public websites, SharePoint, OneDrive, and more.
Rajesh Jha, Microsoft’s head of experiences and devices, is up next at Build to discuss everything Copilot. It’s largely a recap so far, but there’s a lot of new Copilot features on the way.
Microsoft’s new Team Copilot feature will allow the assistant to manage meeting agendas and notes, moderate lengthy team chats, or help assign tasks and track deadlines in Microsoft Planner. It’s part of a new wave of agent capabilities for Copilot that you can read more about right here.
Microsoft CEO Satya Nadella says Sam Altman will appear onstage at Build soon to “talk about what’s next” with Microsoft CTO and EVP of AI Kevin Scott. Will we hear about OpenAI’s search engine, powered partly by Bing? GPT-5? Vague promises of the AI future? Stay tuned.
OpenAI’s latest GPT-4o model is now available for businesses to use through Microsoft’s Azure OpenAI Service. The model includes multimodal input and output, and Microsoft has demonstrated new ways developers can leverage this model for conversational AI in their apps.
Microsoft mentioned yesterday that in addition to all the Snapdragon-powered PCs announced, we would also see those AI PC experiences ship in computers powered by Intel, AMD, and Nvidia as well. Now Nvidia suggests it won’t be a long wait:
In the coming months, Copilot+ PCs equipped with new power-efficient systems-on-a-chip and RTX GPUs will be released, giving gamers, creators, enthusiasts and developers increased performance to tackle demanding local AI workloads, along with Microsoft’s new Copilot+ features.
Microsoft is now allowing businesses to preview its new Arm-based Cobalt CPU on Azure virtual machines. Microsoft CEO Satya Nadella announced onstage at Build that the preview opens today, and these chips should include some performance increases for cloud workloads.
Lots of applause from the developers in the audience at Microsoft Build for the company’s new Windows Copilot Runtime. Microsoft CEO Satya Nadella likens this to a big moment like Win32, allowing developers to more easily build AI into their Windows apps.
Microsoft CEO Satya Nadella has opened Build 2024 by discussing the new AI era. He says Microsoft has had two dreams for decades:
1) Can computers understand us instead of us having to understand computers?
2) In a world where we have ever-increasing information, can computers help us reason, plan, and act more effectively on all that information?
Nadella is positioning this wave of AI as the answer to Microsoft’s dreams.
Fluid Framework 2.0 lets multiple people work together in Microsoft’s Notion-like Loop workspaces and turns Office document items like charts, tables, and lists into “Lego pieces” that can be edited in real time from any app.
Starting today, outside developers are getting preview access to the technology that gave Microsoft 365 apps a Google Workspace-like boost, stretching those abilities for collaboration even further.
