Can I Run Gemma 4 on Apple M4 Pro?
Autor: Jakub Rusinowski · Ostatnia aktualizacja: 12 lipca 2026
Yes, but it's tight — Gemma 4 26B-A4B at Q4_K_M needs 17 GB at 8K context (15.7 GB weights + 1.3 GB KV cache/overhead), leaving ~1 GB of the Apple M4 Pro's 18 GB usable memory, at ~46 tok/s (est.), with room for up to 32K context.

Gemma 4 26B-A4B on the Apple M4 Pro: VRAM by quantization

|---|---|---|---|---|
| F16 | 53.3 GB | ✗ No | — | — |
| Q8_0 | 28.9 GB | ✗ No | — | Build for this |

| Q4_K_M | 17 GB | ✓ Yes | 32K | Build for this |

| Q2_K | 9.8 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 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 M4 Pro: 8K 17 GB · 32K 17.5 GB · 128K 19.5 GB ✗. Past 128K it no longer fits 24 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
No compatible GPU? Gemma 4 26B-A4B on 24 GB of system RAM, CPU only: runs.
