Meta just raised its 2026 AI capex guidance to up to $145 billion — ten billion higher than last quarter — even after posting its strongest revenue growth in five years. Microsoft isn't far behind. We break down last night's earnings, what the market's reaction tells us about investor patience, and what's happening with U.S. AI regulation as state laws multiply and the feds push back.

OpenAI hit $25 billion in annualized revenue faster than any software company in history — and is heading for what could be the biggest tech IPO of the decade. But the losses are enormous, and Anthropic is catching up in the enterprise market faster than most people realize. We also cover the U.S. Air Force using AI inside a live military exercise for the first time, and new research showing AI's labor market impact is already quietly hitting early-career workers.

A Manhattan federal court ruled that AI chatbot conversations carry no attorney-client privilege — and more than a dozen major law firms have now warned clients accordingly. We break down what it means for anyone using AI in a professional context, plus Google's TurboQuant compression breakthrough that could cut AI infrastructure costs in half, and new Stanford data showing the world is more optimistic about AI than Americans are.

GPT-5.5 launched. Google committed $40 billion to Anthropic. Meta and Microsoft cut 20,000 jobs citing AI. DeepSeek V4 arrived built on Chinese chips. The Microsoft-OpenAI deal got rewritten. And then Meta, Microsoft, and Amazon all passed Wall Street's biggest AI earnings test of the quarter. We close out the week — and look at why Novo Nordisk's OpenAI deal is a signal of where the next phase of AI is headed.

This was the quarter where Wall Street stopped taking AI spending on faith. Last night, Meta, Microsoft, and Amazon all reported — and the results mostly backed up the hype. We break down what the numbers say about AI monetization, what Azure growth signals for the sector, and what it means that three companies are collectively spending close to $700 billion on AI this year and still growing earnings.

This morning, Microsoft and OpenAI rewrote their landmark deal — OpenAI can now sell its products across any cloud provider, and Microsoft drops its revenue share obligation. The timing? Hours before both companies report earnings tonight. We break down what changed, what it means for Azure, and what Wall Street is really looking for when Meta and Microsoft report after the bell. Plus: Adobe just rebuilt its entire enterprise platform around AI agents.

China's DeepSeek dropped V4 this week — a frontier-level open-weight model trained entirely on Chinese chips, priced at a fraction of GPT-5.5 and Claude. We break down what makes it a big deal, preview tomorrow's Meta and Microsoft earnings (the most important AI financial test of the quarter), and share a new benchmark showing top AI models still can't produce client-ready work in finance.

Google just committed up to $40 billion to Anthropic, capping a week in which the Claude maker secured as much as $65 billion in fresh funding. Meanwhile, Meta and Microsoft announced workforce cuts totaling more than 20,000 jobs in a single day — and both blamed AI. Plus: why you need to rewrite your GPT-5.5 prompts from scratch, and the lawyer who just got suspended for 20 AI hallucinations in one brief. Your Monday AI briefing — five minutes.

OpenAI just fired back at Anthropic with GPT-5.5, codenamed "Spud" — the first fully retrained model since GPT-4.5. We break down the benchmark battle, Anthropic's rough week of bugs and complaints, Meta's AI-driven layoffs, the surprise App Store boom, and what Stanford's 2026 AI Index says about where this industry is really headed. Five stories, five minutes.

Anthropic launches an AI defense platform that detects and neutralizes sophisticated cyber attacks, including zero-days, with 94% success in red-team simulations.
