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 48GB can run aya expanse 8b with a C grade (Runs well). Expected decode speed: 39.6 tok/s.
aya expanse 8b (8B parameters) requires approximately 11.9 GB of memory with Q4_K_M quantization.
The recommended quantization for aya expanse 8b is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 Pro 48GB, aya expanse 8b achieves approximately 39.6 tokens per second decode speed with a time-to-first-token of 4885ms using Q4_K_M quantization.
For coding workloads, aya expanse 8b on MacBook Pro M4 Pro 48GB receives a C grade with 39.6 tok/s and 403K context.
On MacBook Pro M4 Pro 48GB, aya expanse 8b can safely use up to 403K tokens of context. The model's official context limit is —, but available memory constrains the safe maximum.
Not always. MacBook Pro M4 Pro 48GB 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.
