Meta Chief AI Officer Alexandr Wang stated that the company's most advanced frontier models, such as Muse Wonder, will remain closed-source due to safety and capability concerns, while continuing to release high-quality open-weight alternatives. The newly launched Muse Spark Open is touted as the strongest US open-weight model but performs below the closed flagship. This shift contrasts with CEO Zuckerberg's earlier criticism of competitors for not releasing advanced models, signaling a move toward a tiered open-source strategy.
