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 Pro 48GB can run OLMo 2 32B with a A grade (Tight fit). Expected decode speed: 20.9 tok/s.
OLMo 2 32B (32B parameters) requires approximately 29.5 GB of memory with Q4_K_M quantization.
The recommended quantization for OLMo 2 32B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 Pro 48GB, OLMo 2 32B achieves approximately 20.9 tokens per second decode speed with a time-to-first-token of 9248ms using Q4_K_M quantization.
For coding workloads, OLMo 2 32B on MacBook Pro M4 Pro 48GB receives a A grade with 20.9 tok/s and 4K context.
On MacBook Pro M4 Pro 48GB, OLMo 2 32B can safely use up to 4K tokens of context. The model's official context limit is 4K, but available memory constrains the safe maximum.
Not always. MacBook Pro M4 Pro 48GB 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.
