Meta ships a Mac app for Meta AI, hooks it into Instagram, Facebook, and Google Workspace

Meta is bringing its AI assistant to the desktop. The company launched a native Mac app for Meta AI today, and with it announced that the assistant can now tap directly into Instagram and Facebook accounts, manage Meta ad campaigns, and work inside Google Workspace — a significant expansion beyond its chatbot roots into a full productivity and business tool. The Mac app is Meta's play for the desk. Until now, Meta AI lived inside Instagram, Facebook, Messenger, and WhatsApp — mobile-first surfa

The Take — Why Anthropic's revenue flip means the safety premium is real

Anthropic just passed OpenAI on quarterly revenue for the first time. I think this is the strongest evidence yet that enterprise customers are willing to pay a premium for AI they trust — and that the "safety-first" label, long dismissed as a marketing angle, is now a business strategy with teeth. The numbers that tell the story Anthropic generated more than $11.5 billion in revenue in Q2 2026, more than doubling the $4.73 billion it posted in Q1 and growing 14-fold year over year from $787 m

Tesla puts ByteDance's Doubao AI inside its cars

Tesla has quietly integrated ByteDance's Doubao large language model into its in-car infotainment system, according to multiple Chinese tech outlets including Huxiu, Sina Finance, and Driver Home. The move gives Tesla's Chinese-market vehicles a conversational AI assistant capable of real-time information retrieval and natural dialogue — a significant step beyond the voice-command systems most automakers ship today, and a geopolitically loaded bet on Chinese AI at a time when US-China tech tensi

Google locks in $12.2B Marvell chip warrant as AI silicon race heats up

A pair of deals and a security teardown tell the same story from different angles: the AI infrastructure stack is getting deeper, more expensive, and more contested. Google and Marvell Technology have expanded their custom silicon partnership in a deal that hands Google the right to buy up to 58.97 million Marvell shares at $206.58 each — a package worth up to $12.2 billion at full exercise. The warrant, reported by Bloomberg and confirmed by Reuters, signals that Google is locking in deep cust

Anthropic passes OpenAI on revenue for the first time

The AI race has a new revenue leader. For the first time, Anthropic has overtaken OpenAI in quarterly revenue — a milestone that reshapes the competitive landscape just as OpenAI prepares for its IPO. Anthropic hit $11.6 billion in second-quarter revenue, roughly doubling from the first quarter, while OpenAI reported $6.7 billion — up 18 percent from $5.7 billion in Q1. That puts Anthropic nearly 73 percent ahead of OpenAI on the topline, a gap that would have seemed implausible even twelve mon

xAI multimodal lead joins Tencent's Hunyuan model team

xAI's multimodal understanding lead has decamped for Tencent, signaling a fresh push in China's race to build competitive vision-language models. The move is the latest in a pattern of senior AI researchers crossing between Western labs and Chinese tech giants — and it lands at a moment when multimodal capability is becoming the differentiator for both consumer products and enterprise agents. Lin Xudong, who led multimodal understanding at xAI and contributed to Google DeepMind's Gemini pre-tra

Pentagon pressure pushes defense AI startup Smack to $61M Series B

The Pentagon wants AI on the battlefield faster, and venture capital is following the order. Austin-based Smack Technologies, which builds AI decision-making tools for the US military, announced a $61 million Series B led by Costanoa and First In on Monday, adding fresh fuel to the growing defense-AI pipeline. The round is small in the context of frontier AI spending — but it lands at an inflection point. The Pentagon has been publicly vocal about accelerating AI adoption across logistics, inte

Temporal nears $500M raise at $12B+ as AI orchestration demand surges

Two big moves from the infrastructure side of AI today — one in software, one in hardware — both pointing the same direction: the market is betting heavily on the tools that make AI actually work in production. Temporal is in talks for a fresh funding round that would value the open-source orchestration platform at over $12 billion, with a raise of roughly $500 million. Bloomberg reports the deal is still in progress, but the valuation alone tells the story. Temporal's workflow engine — origina

OpenAI leases 8GW Ohio campus at old uranium plant

The lease we were waiting on is signed: OpenAI is the tenant, Nvidia is the exclusive silicon, and the site used to enrich uranium for the Cold War. OpenAI has signed a 20-year lease on SB Energy's PORTS-Pike Technology Campus in Pike County, Ohio — up to eight gigawatts of AI capacity on the decommissioned Portsmouth Gaseous Diffusion Plant, with Nvidia as the exclusive compute supplier. Nvidia will put up credit support on land, power and the building shell for an initial 4.25 gigawatts, with

OpenAI Q2 sales hit $6.7B as margins sink

The booked quarter is in, and it does not look like the annualized story OpenAI has been selling. OpenAI's second-quarter revenue grew 18 percent from the first quarter to $6.7 billion, according to people familiar with the figures cited by the Wall Street Journal — and its operating margin got worse, though the paper did not say by how much. Some investors were disappointed. The company told them growth picked up again in the third quarter. That is a different object from the $40 billion annua
