Can I Run Qwen 3.5 35B-A3B on Apple M2?
Written by Jakub Rusinowski · Last updated July 12, 2026
Not at Q4_K_M — that needs 23.8 GB at 8K context and the Apple M2 has 18 GB usable. Drop to Q3_K_M and it fits in 17.6 GB, with up to 8K of context.

Qwen 3.5 35B-A3B on the Apple M2: VRAM by quantization

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 24 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: 8K 23.8 GB ✗ · 32K 29.4 GB ✗ · 128K 52 GB ✗. Past 8K it no longer fits 24 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
What to do next
Quantize to Q3_K_M. That is the cheapest fix — it costs some quality but no money.
