This setup is broadly balanced for this model.
Shared-memory contention still exists
The OS, browser, and inference runtime all compete for the same physical memory pool, so real-world headroom is less forgiving than raw capacity suggests.

Yes, Mac mini M4 32GB can run Gemma 3 4B with a B grade (Runs well). Expected decode speed: 25.9 tok/s.
Gemma 3 4B (4B parameters) requires approximately 8.9 GB of memory with Q4_K_M quantization.
The recommended quantization for Gemma 3 4B is Q4_K_M, which balances quality and memory efficiency.
On Mac mini M4 32GB, Gemma 3 4B achieves approximately 25.9 tokens per second decode speed with a time-to-first-token of 7468ms using Q4_K_M quantization.
For coding workloads, Gemma 3 4B on Mac mini M4 32GB receives a B grade with 25.9 tok/s and 125K context.
On Mac mini M4 32GB, Gemma 3 4B can safely use up to 125K tokens of context. The model's official context limit is 128K, but available memory constrains the safe maximum.
Not always. Mac mini M4 32GB can often fit larger models thanks to unified memory, but a discrete GPU with dedicated high-bandwidth VRAM may still decode faster once the model fits. For this combination, the important distinction is capacity versus sustained throughput.
