LeCun Bets Big on World Models, Meta Acquires Moltbook, Thinking Machines Gets a Gigawatt

Today we're covering the biggest AI stories of March 11th, 2026. Meta's former Chief Scientist Yann LeCun launched his long-promised anti-LLM startup, Advanced Machine Intelligence, with over $1 billion in seed funding — backed by Nvidia, Samsung, Bezos, and Mark Cuban — betting that world models, not large language models, are the real path to AI that understands the physical world. Meta made a surprise acquisition of Moltbook, the viral AI agent social network, folding its creators into Zuckerberg's Superintelligence Labs just weeks after losing OpenClaw's creator to OpenAI. Plus, Mira Murati's Thinking Machines Labs secured a massive multiyear Nvidia deal for at least a gigawatt of compute — a loud signal that her startup is far from finished, and a community workflow from a philosophy professor who used AI to rebuild an entire college course from scratch.
