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 432.7 GB, but this setup only exposes 92.2 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 M4 Max 128GB run Mistral Large 3?

No, Mistral Large 3 requires more memory than MacBook Pro M4 Max 128GB provides.

How much VRAM does Mistral Large 3 need?

Mistral Large 3 (675B parameters) requires approximately 432.7 GB of memory with Q4_K_M quantization.

What is the best quantization for Mistral Large 3?

The recommended quantization for Mistral Large 3 is Q4_K_M, which balances quality and memory efficiency.

What speed will Mistral Large 3 run at on MacBook Pro M4 Max 128GB?

On MacBook Pro M4 Max 128GB, Mistral Large 3 achieves approximately 2.0 tokens per second decode speed with a time-to-first-token of 96800ms using Q4_K_M quantization.

Can MacBook Pro M4 Max 128GB run Mistral Large 3 for coding?

For coding workloads, Mistral Large 3 on MacBook Pro M4 Max 128GB receives a F grade with 2.0 tok/s and 4K context.

What context window can Mistral Large 3 use on MacBook Pro M4 Max 128GB?

On MacBook Pro M4 Max 128GB, Mistral Large 3 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 Large 3 feels slow on MacBook Pro M4 Max 128GB?

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 M4 Max 128GB as fast as VRAM for Mistral Large 3?

Not always. MacBook Pro M4 Max 128GB 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.
