Frequently Asked Questions (Llama-3.1-70B-Instruct + Apple M4 Pro Mac Mini (64GB))
Can Apple M4 Pro Mac Mini (64GB) (64GB) run Llama-3.1-70B-Instruct locally?
Yes — Apple M4 Pro Mac Mini (64GB) (64GB) can run Llama-3.1-70B-Instruct using GGUF Q6_K (6-bit). Full FP16 (148.6 GB) exceeds 64 GB VRAM, but 4-bit GGUF Q4_K_M / AWQ requires 47.25 GB (44.09 GB weights + 2.5 GB KV cache at 8K context), delivering ~4.3 tokens/sec.
How is KV Cache calculated for Llama-3.1-70B-Instruct?
Llama-3.1-70B-Instruct uses Dense-GQA with 80 transformer layers, 64 attention heads, and 8 KV heads (head dimension 128). At 8,192 tokens in FP16, KV cache consumes 2.5 GB. Enabling 8-bit KV cache (-ctk q8_0 -ctv q8_0 in llama.cpp or --kv-cache-dtype fp8 in vLLM) cuts this in half to 1.25 GB.
