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 zephyr 7B alpha with a C grade (Runs well). Expected decode speed: 45.3 tok/s.
zephyr 7B alpha (7B parameters) requires approximately 12.9 GB of memory with Q4_K_M quantization.
The recommended quantization for zephyr 7B alpha is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 Pro 64GB, zephyr 7B alpha achieves approximately 45.3 tokens per second decode speed with a time-to-first-token of 4275ms using Q4_K_M quantization.
For coding workloads, zephyr 7B alpha on MacBook Pro M4 Pro 64GB receives a C grade with 45.3 tok/s and 663K context.
On MacBook Pro M4 Pro 64GB, zephyr 7B alpha can safely use up to 663K 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.
