Meta teamed up with Apple to optimize Muse Spark Open for MLX — runs on linked Mac Studios
In a rare public collaboration after years of privacy feuding, Meta worked directly with Apple to optimize the 816B open-weight Muse Spark Open for Apple's MLX framework, so the model splits across 2-4 linked M5 Ultra Mac Studios acting as one supercomputer. Zuckerberg announced it on X; weights are free on Hugging Face under the Muse Model License, though the license carries conditions for large businesses.
