AI IS MY COPILOT

It’s all about AI agents at Microsoft Build

Microsoft announced new “agentic AI” tools for coding, science, and data at its Build 2025 developer conference.

5/19/25 3:41PM

Microsoft announced a bevy of new AI tools at its Build 2025 developer conference in Seattle. The big theme: AI agents are here.

CEO Satya Nadella took the stage for a two-hour presentation outlining the company’s plans for developers. Nadella’s presentation included cameos from some key AI leaders: OpenAI’s Sam Altman, Tesla/X/xAI CEO Elon Musk, and Nvidia’s CEO Jensen Huang.

Microsoft’s $14 billion partnership with OpenAI was recently reported to be fraying due to tension between Nadella and Altman, but the OpenAI CEO was the very first guest for a live interview, which was a completely cordial talk. Altman discussed OpenAI’s new Codex coding agent and how agents are the future of coding.

Nadella also highlighted updates to Copilot — but that requires some unpacking.

There’s Microsoft Copilot 365, which is an AI agent that lurks in your productivity suite of apps and can help generate PowerPoint slides, summarize Microsoft Teams meetings, or analyze your data.

There are also big updates to Github Copilot, an AI tool that helps software developers generate, test, and debug code, which has evolved from an in-editor AI tool to an “asynchronous coding agent.”

That’s not to be confused with plain old Microsoft Copilot, which is just a ChatGPT-style chatbot.

Also there’s Microsoft Copilot Studio, for building new AI agents, and Copilot Tuning, for fine-tuning your AI agents on your company’s proprietary data. (It seems Microsoft didn’t get our memo on the growing AI naming branding confusion.)

Microsoft’s Azure AI cloud computing platform is adding xAI’s Grok3 models. In a prerecorded interview, Musk waxed nostalgic about his early days working with Windows and how the goal with Grok is “to aspire to truth with minimal error.”

Nadella highlighted that Azure AI Foundry lets developers use models from OpenAI, DeepSeek, Mistral, and Meta’s “full heard of llama” models.

Microsoft is now embracing Model Context Protocol into its tools, an open standard developed by Anthropic to standardize the way apps interact with different AI models.

Microsoft also announced a new tool to let companies quickly add conversational chatbots to their websites called NLWeb that can pull from a company’s own data.

For the scientific community, the company announced Microsoft Discovery, an AI-powered research platform that is built to help scientists research, develop hypotheses, and test new discoveries.

At one point during Nadella’s presentation, two protestors disrupted the keynote, challenging the company’s cloud computing contracts with the Israeli government. One protestor turned out to be a Microsoft employee who was able to email several thousand coworkers about the protest after being ejected from the theater.

AI appears to be everywhere, but that doesn’t mean big companies have fully embraced the use of the technology in their day-to-day business.

Report: Microsoft adds Anthropic alongside OpenAI in Office 365, citing better performance

In a move that could test its fraught $13 billion partnership, Microsoft is moving away from relying solely on OpenAI to power its AI features in Office 365 and will now also include Anthropic’s Claude Sonnet 4 model, according to a report from The Information.

The move is a tectonic shift that boosts Anthropic’s standing, heightens risks for OpenAI, and has huge ramifications for the balance of power in the fast-moving AI field.

Per the report, Microsoft executives found that Anthropic’s AI outperformed OpenAI’s on tasks involving spreadsheets and generating PowerPoint slide decks, both crucial parts of Microsoft’s Office 365 productivity suite.

Microsoft will have to pay the competition to provide the services —Amazon Web Services currently hosts Anthropic’s models while Microsoft’s Azure cloud service does not, The Information reported.

OpenAI is also reportedly working on its own productivity suite of apps.

Apple announces extra slim iPhone Air, iPhone Pro with longer battery life, updated AirPods Pro 3 with live language translation, and refreshed Apple Watch line

At today’s “Awe Dropping” Apple event, the company announced its yearly refresh of the iPhone lineup. The new iPhone 17, iPhone 17 Pro, and iPhone 17 Pro Max were joined by a brand-new addition: the iPhone Air, a superthin model with tougher glass and faster processors.

Apple shares dipped on news of the product releases and are down about 1.4% on the day in afternoon trading.

The company also announced an updated Apple Watch line — Series 11, SE3, and Ultra 3 — with new features like 5G, high blood pressure detection, 24-hour battery life, and satellite communication.

Here’s a breakdown of the new products Apple announced:

The ultrathin iPhone Air was described by Apple as “a paradox you have to hold to believe.” The sleek 5.6-millimeter-thin iPhone features a crack- and scratch-resistant front and back and “Macbook Pro levels of compute,” which you can pair with a weird $59 cross-body strap. It starts at $999.
The iPhone 17 has a faster A19 chip, an improved smart selfie camera, and a higher-resolution screen. It starts at $799.
The iPhone 17 Pro has a new design, ever-faster A19 Pro chip, a tougher “ceramic shield” on the front and back, better cameras, and a bigger battery that gets an extra 10 hours of video playback compared to its predecessor. It costs $100 more than the previous generation, but the minimum storage has doubled to 256 gigabytes. It starts at $1,099.
The iPhone 17 Pro Max starts at $1,199.
The AirPods Pro 3 have AI-powered live translation, a new heart rate sensor, eight hours of battery life, and improved active noise cancellation. The new AirPods can also track workouts, and Apple says they are built to fit more people’s ears with a new design and foam ear tips. They start at $249.
The Apple Watch Series 11 has 5G, a new high blood pressure detection feature, improved sleep tracking, a more scratch-resistant face, and 24 hours of battery life.
The entry-level Apple Watch SE 3 gets 5G, new health-tracking features, and an always-on display. It starts at $249.
The chunky Apple Watch Ultra 3 has an impressive 42-hour battery life, satellite communications for emergencies, and a brighter and bigger display. It starts at $799.

Nebius soars after signing a 5-year deal with Microsoft to supply nearly $20 billion worth of AI computing power

Artificial intelligence infrastructure group Nebius jumped more than 50% in early trading on Tuesday after the company announced after the close on Monday a major deal to supply computing power for Microsoft’s AI operations.

Under the agreement, Nebius — which rose from the ashes of Russian tech giant Yandex — will provide Microsoft “access to dedicated GPU infrastructure capacity in tranches at its new data center in Vineland, New Jersey over a five-year term.” The New Jersey data center has a capacity of 300 megawatts. The total contract value through 2031 is $17.4 billion, though, if further capacity is required, the contract value could rise to $19.4 billion.

The deal represents a sizable portion of Microsoft’s proposed annual capital expenditure on AI, which is expected to reach $120 billion by the end of fiscal 2026.

Nebius and competitor CoreWeave are both on the short list of startups that Nvidia has invested in. Nvidia’s small stake in the former is now worth about $120 million.
