Meta open-sources Muse Spark 1.2, launches Muse Glimmer for consumer devices

Meta has unveiled Muse Glimmer, a family of open-source AI models specifically engineered to operate on consumer devices including laptops and smartphones without requiring cloud infrastructure. This represents a technical advancement enabling on-device AI inference, which reduces computational costs and latency compared to cloud-dependent approaches. Additionally, the company open-sourced Muse Spark 1.2 and positioned Muse Glimmer as directly deployable on personal computing hardware, addressing the cost differential between edge and cloud processing. Zuckerberg's accompanying commentary elaborated on policy obstacles affecting American AI development, specifically citing training data restrictions and distillation limitations, and advocated for regulatory modifications to strengthen the competitive position of American open-source models.
