Microsoft Just Cut the OpenAI Cord. GitHub Copilot Gets Its Own AI Model by August.

Microsoft Just Declared AI Independence From OpenAI. Seven Models. No OpenAI Data. A Tenth of the Cost.

Microsoft unveiled seven in-house MAI models at Build — including MAI-Thinking-1, its first reasoning model built entirely without OpenAI distillation, matching Claude Opus 4.6 on coding benchmarks at a tenth of GPT-5.5's cost. Mustafa Suleiman called it "long-term self-sufficiency." We break down what the MAI family actually is, cover Anthropic's Monday IPO filing at a $965 billion valuation, and preview Tim Cook's final WWDC keynote Sunday.

Microsoft Build 2026 opens this morning in San Francisco with one goal: move AI agents from announced to production-ready. We break down the confirmed session tracks, what the Agent Framework graduation means for enterprise developers, and why Microsoft needs to win back developer affection after losing the coding tool satisfaction race to Cursor and Claude Code. Plus: Nvidia confirmed inference revenues just overtook training for the first time — a structural shift in the AI chip market.

Anthropic Just Bought the Developer Tool OpenAI and Google Depended On — Then Shut It Down.

Anthropic acquired Stainless for $300M+ — the SDK generator that powered every official Claude API library, but also OpenAI's, Google's, and Cloudflare's. Then immediately wound down the hosted product for everyone else. We break down the competitive strategy, preview Microsoft Build tomorrow where agents go production-ready and Copilot goes multi-model, and close out the most consequential month in AI history.
