Meta and Apple Release Muse Spark Open, Claiming First Large Model to Run on Apple M5 Ultra Mac Studio
Current overview (not historical)
Meta and Apple have announced Muse Spark Open, a 816‑billion‑parameter multimodal model that they claim is the first of its kind to run efficiently on the Apple M5 Ultra Mac Studio. The model reportedly excels at long‑form tasks, software engineering, and multi‑step reasoning, and is designed to operate on the desktop via Meta’s MLX framework. Meta describes Muse Spark Open as the "most powerful open‑weight model from the United States," while Apple highlights the collaboration’s focus on performance and efficiency on its silicon. The partnership signals a push toward bringing large AI models to consumer hardware, though independent verification of the performance claims remains pending.
