Frequently Asked Questions: Meta Llama 4 Scout (109B-A17B MoE) on Apple Mac Studio M2 Ultra (192GB Unified Memory)
How much VRAM does Meta Llama 4 Scout (109B-A17B MoE) need on Apple Mac Studio M2 Ultra (192GB Unified Memory)?
At standard 4-bit quantization (Q4_K_M) with 32K context, Meta Llama 4 Scout (109B-A17B MoE) requires 71.66 GB of total VRAM (weights + KV cache + CUDA runtime overhead).
What inference speed will Meta Llama 4 Scout (109B-A17B MoE) achieve on Apple Mac Studio M2 Ultra (192GB Unified Memory)?
Based on Apple Mac Studio M2 Ultra (192GB Unified Memory)'s 800 GB/s memory bandwidth, expected decode speed is approximately 47 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.
