Meta’s New AI Model Gives Mark Zuckerberg a Seat at the Big Kid’s Table
Meta Superintelligence Labs has launched Muse Spark, its first model since Zuckerberg torched and rebuilt the company’s entire AI operation — and the benchmarks reportedly look formidable. The catch? Meta, longtime champion of open-source AI and self-appointed sheriff of the frontier model commons, shipped this one closed. As The Register put it, Muse Spark is “as open as Zuckerberg’s private school.” Turns out the open-source religion was a great competitive strategy right up until Meta actually had something worth protecting.
