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 10% 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 1.6 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Frequently asked questions

Can MacBook Pro M3 24GB run Qwen 2.5 32B?

Yes, MacBook Pro M3 24GB can run Qwen 2.5 32B at Q2_K quantization (Very compromised (needs ~1.6 GB host RAM)). The recommended Q4_K_M requires 26.9 GB which exceeds available memory, but at Q2_K it needs only 19.9 GB. Expected decode speed: 4.0 tok/s.

How much VRAM does Qwen 2.5 32B need?

Qwen 2.5 32B (32B parameters) requires approximately 26.9 GB at Q4_K_M quantization. On MacBook Pro M3 24GB, it fits at Q2_K using 19.9 GB.

What is the best quantization for Qwen 2.5 32B?

The recommended quantization is Q4_K_M, but on MacBook Pro M3 24GB the best fitting quantization is Q2_K, which uses 19.9 GB.

What speed will Qwen 2.5 32B run at on MacBook Pro M3 24GB?

On MacBook Pro M3 24GB, Qwen 2.5 32B achieves approximately 4.0 tokens per second decode speed with a time-to-first-token of 48162ms using Q2_K quantization.

Can MacBook Pro M3 24GB run Qwen 2.5 32B for coding?

For coding workloads, Qwen 2.5 32B on MacBook Pro M3 24GB receives a F grade with 2.1 tok/s and 4K context.

What context window can Qwen 2.5 32B use on MacBook Pro M3 24GB?

On MacBook Pro M3 24GB, Qwen 2.5 32B can safely use up to 5K tokens of context at Q2_K quantization. The model's official context limit is 131K, but available memory constrains the safe maximum.

What should I upgrade first if Qwen 2.5 32B feels slow on MacBook Pro M3 24GB?

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 M3 24GB as fast as VRAM for Qwen 2.5 32B?

Not always. MacBook Pro M3 24GB 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.
