1st promptCold start — includes initialization
>Solve: If a train travels at 60 mph for 2.5 hours, how far does it go?
Let me work through this step by step. Given information: - Speed = 60 mph (miles per hour) - Time = 2.5 hours Formula: Distance = Speed x Time Calculation: Distance = 60 mph x 2.5 h = 150 miles The train travels 150 miles. Double-check: at 60 mph the train covers 60 miles each hour. In half an hour it covers 30 miles. So in 2.5 hours: 60 + 60 + 30 = 150 miles. Confirmed.
2nd promptWarm — model ready, no init overhead
>What if the train stops for 20 minutes halfway?
The stop doesn't change the total distance covered while moving, but it affects total trip time. Breakdown: - First half: 1.25 hours at 60 mph = 75 miles - Stop: 20 minutes (no distance) - Second half: 1.25 hours at 60 mph = 75 miles Total distance: 150 miles (same) Total time: 2.5 h + 0.33 h = 2.83 hours Average speed: 150 / 2.83 = 53 mph The distance stays the same but average speed drops to 53 mph because of the stop.

What limits this setup

This setup is broadly balanced for this model.

Very little memory headroom

You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.

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.

Best improvement path

Buy headroom, not only minimum fit

A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.

Frequently asked questions

Can MacBook Pro M2 Pro 32GB run Cerebras-GPT 13B?

Yes, MacBook Pro M2 Pro 32GB can run Cerebras-GPT 13B with a B grade (Runs with offload). Expected decode speed: 14.3 tok/s.

How much VRAM does Cerebras-GPT 13B need?

Cerebras-GPT 13B (13B parameters) requires approximately 23.8 GB of memory with Q5_K_M quantization.

What is the best quantization for Cerebras-GPT 13B?

The recommended quantization for Cerebras-GPT 13B is Q5_K_M, which balances quality and memory efficiency.

What speed will Cerebras-GPT 13B run at on MacBook Pro M2 Pro 32GB?

On MacBook Pro M2 Pro 32GB, Cerebras-GPT 13B achieves approximately 14.3 tokens per second decode speed with a time-to-first-token of 13534ms using Q5_K_M quantization.

Can MacBook Pro M2 Pro 32GB run Cerebras-GPT 13B for coding?

For coding workloads, Cerebras-GPT 13B on MacBook Pro M2 Pro 32GB receives a B grade with 14.3 tok/s and 15K context.

What context window can Cerebras-GPT 13B use on MacBook Pro M2 Pro 32GB?

On MacBook Pro M2 Pro 32GB, Cerebras-GPT 13B can safely use up to 15K tokens of context. The model's official context limit is 131K, but available memory constrains the safe maximum.

What should I upgrade first if Cerebras-GPT 13B feels slow on MacBook Pro M2 Pro 32GB?

Buy headroom, not only minimum fit. A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.

Is unified memory on MacBook Pro M2 Pro 32GB as fast as VRAM for Cerebras-GPT 13B?

Not always. MacBook Pro M2 Pro 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.
