Meta Unveils Muse Spark Following Nine-Month AI Stack Overhaul
Meta has launched Muse Spark, the first language model in its new Muse series, following a comprehensive nine-month reconstruction of its AI architecture.

What happened?
Meta's research division, Superintelligence Labs, has introduced Muse Spark, the first large-scale language model in the company's new Muse series. The model is the result of a nine-month effort to rebuild Meta's internal AI development stack from scratch. The series is designed to scale iteratively through scientific validation in each generation.
