Can I Run Qwen 3.5 9B on Apple M1 Pro?
Written by Jakub Rusinowski · Last updated July 12, 2026
Yes. Qwen 3.5 9B needs 6.5 GB at 8K context (5.4 GB weights + 1.1 GB KV cache/overhead) at Q4_K_M and the Apple M1 Pro has 24 GB usable, leaving about 17.5 GB of headroom, at roughly 19 tok/s (estimated) with room for up to 128K of context.

Qwen 3.5 9B on the Apple M1 Pro: VRAM by quantization
| Quant | VRAM needed | Fits 32 GB? | Max context | Whole PC |
|---|---|---|---|---|
| F16 | 19.1 GB | ✓ Yes | 128K | — |
| Q8_0 | 10.6 GB | ✓ Yes | 128K | Build for this |
| Q6_K | 8.4 GB | ✓ Yes | 128K | — |
| Q5_K_M | 7.4 GB | ✓ Yes | 128K | — |
| Q4_K_M | 6.5 GB | ✓ Yes | 128K | Build for this |
| Q3_K_M | 4.9 GB | ✓ Yes | 128K | — |
| Q2_K | 4 GB | ✓ Yes | 128K | — |
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 32 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 Pro: 8K 6.5 GB · 32K 7.3 GB · 128K 10.5 GB. Every window this model publishes still fits 32 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.
