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 M1 Max 64GB can run Phi-4-reasoning-plus 14B with a S grade (Runs well). Expected decode speed: 26.4 tok/s.
Phi-4-reasoning-plus 14B (14.699999809265137B parameters) requires approximately 19.8 GB of memory with Q4_K_M quantization.
The recommended quantization for Phi-4-reasoning-plus 14B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M1 Max 64GB, Phi-4-reasoning-plus 14B achieves approximately 26.4 tokens per second decode speed with a time-to-first-token of 7340ms using Q4_K_M quantization.
For coding workloads, Phi-4-reasoning-plus 14B on MacBook Pro M1 Max 64GB receives a S grade with 26.4 tok/s and 33K context.
On MacBook Pro M1 Max 64GB, Phi-4-reasoning-plus 14B can safely use up to 33K tokens of context. The model's official context limit is 33K, but available memory constrains the safe maximum.
Not always. MacBook Pro M1 Max 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.
