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 64GB can run Phi 4 reasoning vision 15B with a C grade (Runs well). Expected decode speed: 21.2 tok/s.
Phi 4 reasoning vision 15B (15B parameters) requires approximately 18.7 GB of memory with Q4_K_M quantization.
The recommended quantization for Phi 4 reasoning vision 15B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 Pro 64GB, Phi 4 reasoning vision 15B achieves approximately 21.2 tokens per second decode speed with a time-to-first-token of 9120ms using Q4_K_M quantization.
For coding workloads, Phi 4 reasoning vision 15B on MacBook Pro M4 Pro 64GB receives a C grade with 21.2 tok/s and 265K context.
On MacBook Pro M4 Pro 64GB, Phi 4 reasoning vision 15B can safely use up to 265K tokens of context. The model's official context limit is —, but available memory constrains the safe maximum.
Not always. MacBook Pro M4 Pro 64GB 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.
