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 Cerebras-GPT 13B with a B grade (Runs well). Expected decode speed: 22.9 tok/s.
Cerebras-GPT 13B (13B parameters) requires approximately 25.5 GB of memory with Q5_K_M quantization.
The recommended quantization for Cerebras-GPT 13B is Q5_K_M, which balances quality and memory efficiency.
On MacBook Pro M4 Pro 48GB, Cerebras-GPT 13B achieves approximately 22.9 tokens per second decode speed with a time-to-first-token of 8451ms using Q5_K_M quantization.
For coding workloads, Cerebras-GPT 13B on MacBook Pro M4 Pro 48GB receives a B grade with 22.9 tok/s and 31K context.
On MacBook Pro M4 Pro 48GB, Cerebras-GPT 13B can safely use up to 31K tokens of context. The model's official context limit is 131K, 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.
