Can I Run Gemma 3 1B Instruct on Apple M2 Pro?
Written by Jakub Rusinowski · Last updated September 29, 2026
Yes. Gemma 3 1B Instruct needs 2 GB at 8K context (0.6 GB weights + 1.4 GB KV cache/overhead) at Q4_K_M and the Apple M2 Pro has 24 GB usable, leaving about 22 GB of headroom, at roughly 89 tok/s (estimated) with room for up to 32K of context.

Gemma 3 1B Instruct on the Apple M2 Pro: VRAM by quantization
| Quant | VRAM needed | Fits 32 GB? | Max context | Whole PC |
|---|---|---|---|---|
| F16 | 3.4 GB | ✓ Yes | 32K | — |
| Q8_0 | 2.5 GB | ✓ Yes | 32K | — |
| Q6_K | 2.2 GB | ✓ Yes | 32K | — |
| Q5_K_M | 2.1 GB | ✓ Yes | 32K | — |
| Q4_K_M | 2 GB | ✓ Yes | 32K | — |
| Q3_K_M | 1.8 GB | ✓ Yes | 32K | — |
| Q2_K | 1.7 GB | ✓ Yes | 32K | — |
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 2 GB · 32K 3.8 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.
