Can I Run Gemma 4 26B-A4B on Apple M2 Pro?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 29 września 2026
Yes. Gemma 4 26B-A4B needs 17 GB at 8K context (15.7 GB weights + 1.3 GB KV cache/overhead) at Q4_K_M and the Apple M2 Pro has 24 GB usable, leaving about 7 GB of headroom, at roughly 35 tok/s (estimated) with room for up to 128K of context.

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 M2 Pro: 8K 17 GB · 32K 17.5 GB · 128K 19.5 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.
