Apple: Muse Spark Open tops 36 tokens a second on four Mac Studios

Apple's ML research team says four M5 Ultra Mac Studios run Meta's 816B model at over 36 tokens per second with MLX. AWS added it to SageMaker JumpStart. In Epoch AI's run it scored 0.886 on GPQA diamond.

Why it matters: A frontier-class open model can now run on desk hardware or in your own cloud account, keeping code private. CNBC says the required Mac Studio starts at $10,799.
