Key points
- Local and Distributed Large LLM Inference with MLX and RDMA on Mac Studio
- Following Muse Glimmer, Muse Spark Open introduces a mixture-of-experts architecture at a much larger scale, and the most capable US open-weights model to date.
- Meta launches Muse Spark Open, a coding-optimized 816B mixture-of-experts (MoE) model with 42B active parameters and a 1M token context window.
- A version of Muse Spark Open was released today, fulfilling their original promise but with a model weaker than their Spark 1.3.
