xAI launches Grok 4, Grok 4 Heavy, SuperGrok Heavy

The launch of a major new version of the Grok AI model should be a triumphant moment for Elon Musk’s xAI, but a week of self-induced chaos has overshadowed the release.

During a midnight livestream on X, Elon Musk was joined by xAI researchers in an awkward product launch for Grok 4, the latest version of the company’s “reasoning” foundational AI model, which Musk called “the smartest AI in the world.”

Several demos walked through the advanced capabilities of the new model, which the company says beats leading state-of-the-art models from OpenAI in several academic and coding benchmarks. Musk also highlighted Grok 4’s new high score in the challenging ARC-AGI 2 benchmark.

Two versions of the model were announced: Grok 4 and Grok 4 Heavy. Access to Grok 4 Heavy requires a $300 per month “SuperGrok Heavy” subscription.

But hanging over all that was a big screwup: just yesterday, the company announced it was removing a number of antisemitic posts that it called “offensive” after Musk forced changes to the Grok chatbot with instructions to not shy away from “politically incorrect claims.” This was followed by X CEO Linda Yaccarino announcing her departure after two years.

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.
