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, MacBook Pro M4 Max 96GB can run Gemma 4 31B with a S grade (Runs well). Expected decode speed: 25.5 tok/s.
Gemma 4 31B (30.700000762939453B parameters) requires approximately 44.6 GB of memory with Q4_K_M quantization.
The recommended quantization for Gemma 4 31B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 Max 96GB, Gemma 4 31B achieves approximately 25.5 tokens per second decode speed with a time-to-first-token of 7586ms using Q4_K_M quantization.
For coding workloads, Gemma 4 31B on MacBook Pro M4 Max 96GB receives a S grade with 25.5 tok/s and 43K context.
On MacBook Pro M4 Max 96GB, Gemma 4 31B can safely use up to 43K tokens of context. The model's official context limit is 256K, but available memory constrains the safe maximum.
Not always. MacBook Pro M4 Max 96GB 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.
