Odaily Planet Daily reports that Meta Platforms (META.O) has launched a new open-weight AI model, Muse Spark Open, primarily targeting programming and AI agent tasks, but has not released its most powerful model. Meta’s Chief AI Officer, Alexandr Wang, stated that Muse Spark Open is not the strongest model developed or released by the company.
Meta’s Muse Wonder, launched earlier this week, remains closed-source. Meta also acknowledged that China’s open-weight models still outperform Muse Spark Open in software development and certain other tasks. Meanwhile, Meta has partnered with Apple (AAPL.O) to enable developers to run Muse Spark Open locally on multiple high-end Mac computers. Apple has updated its MLX software toolkit to support the model on Mac devices.
