Apple ML Research: Muse Spark Open with MLX on Mac Studio

Local and Distributed Large LLM Inference with MLX and RDMA on Mac Studio

MLX on Mac with Apple silicon lets AI researchers and developers experiment locally with the latest models and methods in a private environment. The open-source array framework leverages the unified memory architecture of Apple silicon, enabling anyone to run new inference and fine-tuning methods on their own hardware and explore other AI techniques. In a previous post , we highlighted the advantages of the M5 architecture and its GPU Neural Accelerators.

In this post, we show how to run the latest frontier-class model — Muse Spark Open, with nearly a trillion parameters — right from your desk, using the latest version of MLX, released today. On a cluster of four Mac Studios, Muse Spark Open generates over 36 tokens per second (see Figure 1 ), well above average human reading speed.
