SpaceX Buys Cursor for $60B, Z AI's Open Model Rivals the Frontier, Meta's AI Morale Crisis

Today we're covering the biggest AI stories of June 17th, 2026. SpaceX officially closed its $60 billion all-stock acquisition of Cursor — funded almost entirely by a post-IPO rally that doubled the company's value in under a week — with Cursor CEO Michael Truell teasing that their next model will be "generally intelligent," trained from scratch, and Opus-sized, giving Elon Musk a serious coding platform for his entire AI stack just as Grok Build launches. Chinese AI lab Z AI released GLM-5.2, an open-weights model with a 1 million token context window that beats GPT-5.5 on real-world coding benchmarks and comes in just below Opus 4.8 — at a fraction of the cost, with an MIT license, arriving at exactly the moment users are scrambling for alternatives after Fable went dark. Plus, Meta CTO Andrew Bosworth posted a public memo admitting the company "did an atrocious job explaining the vision" of its AI reorg — with employees calling the unit a gulag, someone hijacking a company livestream to trash a senior executive, and Bosworth promising better snack kitchens and social events as his main concession — and today's community workflow comes from Leona in Burlington, Ontario, who used ChatGPT to build a personalized running coach for women in their 40s, ran her first 10K last year, her second this year, and already has her 2027 race plan mapped out.
