My dear friend, Rob Mesirow, died on April 22. He was 57. I am heartbroken. Rob was one of those rare people who made everyone around him better. He listened, really listened, in a way that made you feel like the only person in the room. In an industry full of people waiting for their turn to talk, Rob was waiting to understand.

Google, Microsoft, Meta, and Amazon collectively committed approximately $700 billion to AI infrastructure spending this year, a 77% increase over 2025. All four reported earnings this week. Every single one beat expectations. The stock market yawned. Continue Reading →

OpenAI just shipped GPT-5.5, seven weeks after GPT-5.4, and OpenAI President Greg Brockman called it “a new class of intelligence.” That is a big claim. It is also useful framing. GPT-5.5 is built for work that crosses tools, screens, files, codebases, spreadsheets, research trails, and humans who occasionally give instructions like, “Just make it work.” Continue Reading →

OpenAI launched "workspace agents" in ChatGPT yesterday. Powered by Codex, these persistent, autonomous agents run in the cloud, integrate with ChatGPT and Slack, and handle complex workflows across tools and teams.

OpenAI is adding CPC (cost-per-click) to ChatGPT ads this week. Advertisers can now bid $3 to $5 per click, which puts ChatGPT somewhere between Meta (cheap clicks, browsing intent) and Google Search (expensive clicks, purchase intent).
