Qwen3.5 9B needs ~14.4 GB VRAM. MacBook Pro M4 Pro 64GB has 46.1 GB. With Q4_K_M quantization, expect ~35 tok/s.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.

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 Qwen3.5 9B with a C grade (Runs well). Expected decode speed: 35.2 tok/s.
Qwen3.5 9B (9B parameters) requires approximately 14.4 GB of memory with Q4_K_M quantization.
The recommended quantization for Qwen3.5 9B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 Pro 64GB, Qwen3.5 9B achieves approximately 35.2 tokens per second decode speed with a time-to-first-token of 5496ms using Q4_K_M quantization.
For coding workloads, Qwen3.5 9B on MacBook Pro M4 Pro 64GB receives a C grade with 35.2 tok/s and 497K context.
On MacBook Pro M4 Pro 64GB, Qwen3.5 9B can safely use up to 497K 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.
