Yesterday in AI | Tuesday, April 28, 2026
OpenAI just broke up with Microsoft. Sort of. And China just proved no AI startup is safe.
Two massive deals fell apart or got rewritten in a single day — and they say more about where AI power is actually concentrating than any benchmark ever could. One company that invented the AlphaGo era just raised $1.1 billion to throw out everything the industry has built. And Sam Altman published his principles the day after something happened in a small Canadian town that you need to hear about. Also: OpenAI is building a phone, and Google told us a number today that should change how every engineering leader thinks about headcount.
