Can I Run Command R Family on Apple M4 Max?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 29 września 2026
Yes, comfortably — Command R+ (104B) at Q4_K_M needs 65.7 GB at 8K context (62.8 GB weights + 2.9 GB KV cache/overhead), leaving ~30.3 GB of the Apple M4 Max's 96 GB usable memory, at ~5 tok/s (est.), with room for up to 64K context.

Assumes an 8K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 128 GB of unified memory. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the Apple M4 Max: 8K 65.7 GB · 32K 72.2 GB · 125K 97.1 GB ✗. Past 125K it no longer fits 128 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Command R+ (104B) on 256 GB of system RAM, CPU only: runs, but too slowly to be worth it.
