Meta released the weights for Muse Spark Open, a natively multimodal mixture-of-experts model with 816B total parameters (42B active) and a 1M-token context window, built for coding and long-horizon agentic work. Meta calls it the most capable US open-weight model to date and says it runs entirely on-device across two 512GB M5 Ultra Mac Studios via MLX.
Alberta votes Monday on whether to remain a province or instruct its government to begin the legal process toward a future independence referendum.
