All of the news from Microsoft’s 50th Anniversary Copilot event

Microsoft is holding a 50th Anniversary Copilot livestream today at 12:30PM ET / 9:30AM PT on April 4th, the same day Microsoft founders Bill Gates and Paul Allen started the company in 1975. Dubbed “Introducing your AI companion,” it’s set up for Microsoft to show off some significant updates to its Windows AI assistant.

You can watch the livestream right here via the YouTube stream or directly from Microsoft.

Microsoft announced the event last month, which features Microsoft CEO Satya Nadella, Microsoft AI CEO Mustafa Suleyman, and “leaders of past and present.”

Microsoft recently announced deep research and other “agentic” updates to Copilot in Microsoft 365, and a more significant reboot could help it keep up with tools released for competing AI platforms like ChatGPT and Gemini. CEO Satya Nadella recently commented on the success of DeepSeek’s AI, saying to employees that “What’s most impressive about DeepSeek is that it’s a great reminder of what 200 people can do when they come together with one thought and one play… not just leaving it there as a research project or an open source project, but to turn it into a product that was number one in the App Store. That’s the new bar to me.”
