Can I run Gemma 3 4B on Apple M5 (16GB)?
Yes. Gemma 3 4B runs on Apple M5 (16GB) at Q4_K_M (~3.8 GB of ~10.5 GB usable).
Runs at Q4_K_M using ~3.8 GB of ~10.5 GB usable. You have room for FP16 for higher quality.
That figure is at a 4k context and moves about ±15% as context length changes. Apple M5 (16GB) leaves ~6.7 GB of headroom, room to step up to FP16 for higher quality.

FAQ
Can Apple M5 (16GB) run Gemma 3 4B?
Yes. Gemma 3 4B runs on Apple M5 (16GB) at Q4_K_M (~3.8 GB of ~10.5 GB usable).
How much memory does Gemma 3 4B need?
Apple M5 (16GB) has room to spare. At Q4_K_M the weights are ~2.49 GB; with KV cache and runtime overhead, budget ~3.8 GB at a 4k context.
What is the best tool to run Gemma 3 4B on macOS?
LM Studio for a simple setup; mlx-lm for the most speed. vLLM is NOT a Mac tool, it is a CUDA/Linux serving engine. Unified memory is not a fixed VRAM slice; ~70% is usable for weights.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
