Can I Run Llama 3.2 1B Instruct on Apple M4 Max?
作者： Jakub Rusinowski · 最后更新： 2026年9月29日
Yes. Llama 3.2 1B Instruct needs 1.8 GB at 8K context (0.7 GB weights + 1.1 GB KV cache/overhead) at Q4_K_M and the Apple M4 Max has 96 GB usable, leaving about 94.2 GB of headroom, at roughly 168 tok/s (estimated) with room for up to 64K of context.

|---|---|---|---|---|
| F16 | 3.5 GB | ✓ Yes | 64K | — |
| Q8_0 | 2.4 GB | ✓ Yes | 64K | — |
| Q6_K | 2.1 GB | ✓ Yes | 64K | — |
| Q5_K_M | 1.9 GB | ✓ Yes | 64K | — |
| Q4_K_M | 1.8 GB | ✓ Yes | 64K | — |

| Q2_K | 1.5 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 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 1.8 GB · 32K 2.6 GB · 125K 5.7 GB. Every window this model publishes still fits 128 GB.
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.
