Can I Run Qwen 3.5 122B-A10B on Apple M3 Pro?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 29 września 2026
No. Qwen 3.5 122B-A10B needs 77.3 GB at 8K context (73.7 GB weights + 3.6 GB KV cache/overhead) at Q4_K_M and the Apple M3 Pro has only 27 GB usable. No quantization we publish closes a gap that size.

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 36 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 M3 Pro: 8K 77.3 GB ✗ · 32K 85.9 GB ✗ · 128K 120.1 GB ✗. Past 8K it no longer fits 36 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Either step down to a smaller size in this family, or move to a NVIDIA A100 80GB (PCIe) (80 GB), the card with the least memory we track that holds it.
