Zuckerberg Attacks 'Closed' Rivals and Blames US Training-Data Rules for Ceding Open Models to China
Paired with the Muse Glimmer release, Zuckerberg argued that "foreign labs currently hold several advantages here since American labs have to comply with many additional restrictions on training data" and that "US policy must reduce this additional friction if we want American open source models to lead over time." The FT framing of Meta "returning" to open models drew 535 points and 488 comments on HN — one of the most contested threads of the day, given Meta's own 2025 signals that it likely would not open-source its superintelligence models. Worth reading as the reversal it is, not as continuity.
