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

Usable shared or unified memory is the main blocker for this model.

Not enough usable memory

The model needs 82.7 GB, but this setup only exposes 25.9 GB of usable shared or unified memory.

Best improvement path

Move to a larger memory pool

A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.

Frequently asked questions

Can MacBook Pro M3 Pro 36GB run Mistral Small 4 119B?

No, Mistral Small 4 119B requires more memory than MacBook Pro M3 Pro 36GB provides.

How much VRAM does Mistral Small 4 119B need?

Mistral Small 4 119B (119B parameters) requires approximately 82.7 GB of memory with Q4_K_M quantization.

What is the best quantization for Mistral Small 4 119B?

The recommended quantization for Mistral Small 4 119B is Q4_K_M, which balances quality and memory efficiency.

What speed will Mistral Small 4 119B run at on MacBook Pro M3 Pro 36GB?

On MacBook Pro M3 Pro 36GB, Mistral Small 4 119B achieves approximately 3.3 tokens per second decode speed with a time-to-first-token of 58153ms using Q4_K_M quantization.

Can MacBook Pro M3 Pro 36GB run Mistral Small 4 119B for coding?

For coding workloads, Mistral Small 4 119B on MacBook Pro M3 Pro 36GB receives a F grade with 3.3 tok/s and 4K context.

What context window can Mistral Small 4 119B use on MacBook Pro M3 Pro 36GB?

On MacBook Pro M3 Pro 36GB, Mistral Small 4 119B can safely use up to 4K tokens of context. The model's official context limit is 256K, but available memory constrains the safe maximum.

What should I upgrade first if Mistral Small 4 119B feels slow on MacBook Pro M3 Pro 36GB?

Move to a larger memory pool. A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.

Is unified memory on MacBook Pro M3 Pro 36GB as fast as VRAM for Mistral Small 4 119B?

Not always. MacBook Pro M3 Pro 36GB 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.
