Can I Run Llama 3.2 3B Instruct on Apple M2 Max?
作者： Jakub Rusinowski · 最后更新： 2026年9月29日
Yes. Llama 3.2 3B Instruct needs 3.7 GB at 8K context (1.9 GB weights + 1.8 GB KV cache/overhead) at Q4_K_M and the Apple M2 Max has 72 GB usable, leaving about 68.3 GB of headroom, at roughly 72 tok/s (estimated) with room for up to 64K of context.

Llama 3.2 3B Instruct on the Apple M2 Max: VRAM by quantization
| Quant | VRAM needed | Fits 96 GB? | Max context | Whole PC |
|---|---|---|---|---|
| F16 | 8.2 GB | ✓ Yes | 64K | — |
| Q8_0 | 5.2 GB | ✓ Yes | 64K | — |
| Q6_K | 4.4 GB | ✓ Yes | 64K | — |
| Q5_K_M | 4 GB | ✓ Yes | 64K | — |
| Q4_K_M | 3.7 GB | ✓ Yes | 64K | — |
| Q3_K_M | 3.1 GB | ✓ Yes | 64K | — |
| Q2_K | 2.8 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 96 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 M2 Max: 8K 3.7 GB · 32K 6.5 GB · 125K 17.4 GB. Every window this model publishes still fits 96 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.
