Usable shared or unified memory is the main blocker for this model.
Not enough usable memory
The model needs 24.6 GB, but this setup only exposes 11.5 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, Aya Expanse 32B requires more memory than MacBook Pro M4 16GB provides.
Aya Expanse 32B (32B parameters) requires approximately 24.6 GB of memory with Q4_K_M quantization.
The recommended quantization for Aya Expanse 32B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 16GB, Aya Expanse 32B achieves approximately 3.9 tokens per second decode speed with a time-to-first-token of 49654ms using Q4_K_M quantization.
For coding workloads, Aya Expanse 32B on MacBook Pro M4 16GB receives a F grade with 3.9 tok/s and 4K context.
On MacBook Pro M4 16GB, Aya Expanse 32B can safely use up to 4K tokens of context. The model's official context limit is 8K, 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 M4 16GB 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.
