Architecture & Throughput Transparency: Single-user decode speed (~0 tok/s) is memory-bandwidth bound at batch size = 1 on Apple MacBook Pro/Air (16GB Unified Memory) (100 GB/s). Prompt prefill / TTFT (~0 tok/s) is compute-bound and utilizes GPU Tensor cores. Actual latency varies with FlashAttention-2 and runtime engine (Ollama/vLLM/llama.cpp).
MoE Memory vs Speed Architecture: While decode throughput scales with the active parameter count (42B parameters streamed per token), all 816B parameters must be resident in VRAM so the dynamic router can route tokens to any expert layer.

FAQ & Reference

Frequently Asked Questions: Meta Muse Spark Open (816B-A42B MoE) on Apple MacBook Pro/Air (16GB Unified Memory)

How much VRAM does Meta Muse Spark Open (816B-A42B MoE) need on Apple MacBook Pro/Air (16GB Unified Memory)?

At standard 4-bit quantization (Q4_K_M) with 32K context, Meta Muse Spark Open (816B-A42B MoE) requires 512.86 GB of total VRAM (weights + KV cache + CUDA runtime overhead).

What inference speed will Meta Muse Spark Open (816B-A42B MoE) achieve on Apple MacBook Pro/Air (16GB Unified Memory)?

Based on Apple MacBook Pro/Air (16GB Unified Memory)'s 100 GB/s memory bandwidth, expected decode speed is approximately 0 tokens per second.

Can I expand context beyond 32K tokens?

Each additional 32K tokens of context requires additional KV cache memory. For longer context windows, consider 8-bit or 4-bit KV cache quantization.
