Qwen 3.5 397B A17B needs ~249.4 GB but MacBook Pro M2 Max 32GB only has 23.0 GB. Try a smaller quantization or lighter model.
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.
Current mode
Balanced
Balanced for general local use. Keeps the ranking neutral across personal and serving workflows.

Usable shared or unified memory is the main blocker for this model.
Not enough usable memory
The model needs 249.4 GB, but this setup only exposes 23.0 GB of usable shared or unified memory.
Move to a larger memory pool
A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.

No, Qwen 3.5 397B A17B requires more memory than MacBook Pro M2 Max 32GB provides.
Qwen 3.5 397B A17B (397B parameters) requires approximately 249.4 GB of memory with Q4_K_M quantization.
The recommended quantization for Qwen 3.5 397B A17B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M2 Max 32GB, Qwen 3.5 397B A17B achieves approximately 2.2 tokens per second decode speed with a time-to-first-token of 88543ms using Q4_K_M quantization.
For coding workloads, Qwen 3.5 397B A17B on MacBook Pro M2 Max 32GB receives a F grade with 2.2 tok/s and 4K context.
On MacBook Pro M2 Max 32GB, Qwen 3.5 397B A17B can safely use up to 4K tokens of context. The model's official context limit is 131K, but available memory constrains the safe maximum.
Move to a larger memory pool. A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.
Not always. MacBook Pro M2 Max 32GB 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.
