作者： Jakub Rusinowski · 最后更新： 2026年7月12日
No — MiniMax M3 428B-A23B at Q4_K_M needs 263.6 GB at 8K context (258.4 GB weights + 5.2 GB KV cache/overhead), and the Apple M5 Pro's 48 GB usable memory leaves it ~215.6 GB short. The cheapest card that runs it is the Apple M5 Ultra (512 GB).

Assumes an 8K-token context with an f16 KV cache, on an estimated architecture — this model publishes no config we can read. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 64 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 M5 Pro: 8K 263.6 GB ✗ · 32K 276.7 GB ✗ · 128K 329 GB ✗. Past 8K it no longer fits 64 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? MiniMax M3 428B-A23B on 192 GB of system RAM, CPU only: runs, but it is tight.
Why It Does Not Fit
Every MiniMax M3 variant requires more VRAM than the Apple M5 Pro provides (64 GB).
Nearest GPU That Fits
Apple M5 Ultra (512 GB VRAM).
MiniMax M3 needs ~264 GB but this GPU has 64 GB. Rent a 8× H100 (640 GB)-class GPU by the hour instead of buying one:
