1st promptCold start — includes initialization
>Write a Python function to sort a list
Here's a Python function that sorts a list using quicksort: def quicksort(arr): if len(arr) <= 1: return arr pivot = arr[len(arr) // 2] left = [x for x in arr if x < pivot] middle = [x for x in arr if x == pivot] right = [x for x in arr if x > pivot] return quicksort(left) + middle + quicksort(right) # Example usage numbers = [3, 6, 8, 10, 1, 2, 1] print(quicksort(numbers)) # [1, 1, 2, 3, 6, 8, 10] The algorithm picks a pivot, partitions the list into smaller, equal, and larger elements, then recursively sorts each partition and concatenates the results.
2nd promptWarm — model ready, no init overhead
>Now add type hints and a docstring
def quicksort(arr: list[int]) -> list[int]: """Sort a list using the quicksort algorithm. Args: arr: List of integers to sort. Returns: A new sorted list. """ if len(arr) <= 1: return arr pivot = arr[len(arr) // 2] left = [x for x in arr if x < pivot] middle = [x for x in arr if x == pivot] right = [x for x in arr if x > pivot] return quicksort(left) + middle + quicksort(right) Added type hints for the input and return type, plus a Google-style docstring.

What limits this setup

It fits through host-memory offload, and offload is the main reason performance drops.

CPU or host-memory offload is active

About 20% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.

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

Remove offload with more accelerator memory

Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.

Buy headroom, not only minimum fit

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

Increase host RAM if you keep offloading

This setup may need roughly 1.3 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Frequently asked questions

Can MacBook Pro M2 Pro 16GB run DeepSeek Coder V2 16B?

Yes, MacBook Pro M2 Pro 16GB can run DeepSeek Coder V2 16B at Q3_K_S quantization (Very compromised (needs ~1.3 GB host RAM)). The recommended Q4_K_M requires 15.7 GB which exceeds available memory, but at Q3_K_S it needs only 13.8 GB. Expected decode speed: 30.3 tok/s.

How much VRAM does DeepSeek Coder V2 16B need?

DeepSeek Coder V2 16B (16B parameters) requires approximately 15.7 GB at Q4_K_M quantization. On MacBook Pro M2 Pro 16GB, it fits at Q3_K_S using 13.8 GB.

What is the best quantization for DeepSeek Coder V2 16B?

The recommended quantization is Q4_K_M, but on MacBook Pro M2 Pro 16GB the best fitting quantization is Q3_K_S, which uses 13.8 GB.

What speed will DeepSeek Coder V2 16B run at on MacBook Pro M2 Pro 16GB?

On MacBook Pro M2 Pro 16GB, DeepSeek Coder V2 16B achieves approximately 30.3 tokens per second decode speed with a time-to-first-token of 6395ms using Q3_K_S quantization.

Can MacBook Pro M2 Pro 16GB run DeepSeek Coder V2 16B for coding?

For coding workloads, DeepSeek Coder V2 16B on MacBook Pro M2 Pro 16GB receives a F grade with 22.3 tok/s and 4K context.

What context window can DeepSeek Coder V2 16B use on MacBook Pro M2 Pro 16GB?

On MacBook Pro M2 Pro 16GB, DeepSeek Coder V2 16B can safely use up to 5K tokens of context at Q3_K_S quantization. The model's official context limit is 131K, but available memory constrains the safe maximum.

What should I upgrade first if DeepSeek Coder V2 16B feels slow on MacBook Pro M2 Pro 16GB?

Remove offload with more accelerator memory. Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.

Is unified memory on MacBook Pro M2 Pro 16GB as fast as VRAM for DeepSeek Coder V2 16B?

Not always. MacBook Pro M2 Pro 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.
