Can I Run Qwen 2.5 72B Instruct on Apple M1 Max?
作者： Jakub Rusinowski · 最后更新： 2026年9月29日
Yes, but it's tight. Qwen 2.5 72B Instruct needs 47 GB at 8K context (43.5 GB weights + 3.5 GB KV cache/overhead) at Q4_K_M and the Apple M1 Max has 48 GB usable, leaving about 1 GB of headroom, at roughly 5 tok/s (estimated) with room for up to 8K of context.

Qwen 2.5 72B Instruct on the Apple M1 Max: VRAM by quantization
| Quant | VRAM needed | Fits 64 GB? | Max context | Whole PC |
|---|---|---|---|---|
| F16 | 147.5 GB | ✗ No | — | — |
| Q8_0 | 80 GB | ✗ No | — | — |
| Q6_K | 62.5 GB | ✗ No | — | — |
| Q5_K_M | 54.5 GB | ✗ No | — | — |
| Q4_K_M | 47 GB | ✓ Yes | 8K | — |

| Q2_K | 27.2 GB | ✓ Yes | 64K | — |
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 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 M1 Max: 8K 47 GB · 32K 55 GB ✗ · 128K 87.2 GB ✗. Past 32K it no longer fits 64 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
