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

This setup is broadly balanced for this model.

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.

Frequently asked questions

Can NVIDIA DGX Spark 128GB run DeepSeek R1 Distill 7B?

Yes, NVIDIA DGX Spark 128GB can run DeepSeek R1 Distill 7B at F16 quantization (Runs well). The recommended Q4_K_M requires 6.3 GB which exceeds available memory, but at F16 it needs only 29.5 GB. Expected decode speed: 17.4 tok/s.

How much VRAM does DeepSeek R1 Distill 7B need?

DeepSeek R1 Distill 7B (7B parameters) requires approximately 6.3 GB at Q4_K_M quantization. On NVIDIA DGX Spark 128GB, it fits at F16 using 29.5 GB.

What is the best quantization for DeepSeek R1 Distill 7B?

The recommended quantization is Q4_K_M, but on NVIDIA DGX Spark 128GB the best fitting quantization is F16, which uses 29.5 GB.

What speed will DeepSeek R1 Distill 7B run at on NVIDIA DGX Spark 128GB?

On NVIDIA DGX Spark 128GB, DeepSeek R1 Distill 7B achieves approximately 17.4 tokens per second decode speed with a time-to-first-token of 11158ms using F16 quantization.

Can NVIDIA DGX Spark 128GB run DeepSeek R1 Distill 7B for coding?

For coding workloads, DeepSeek R1 Distill 7B on NVIDIA DGX Spark 128GB receives a F grade with 6.9 tok/s and 4K context.

What context window can DeepSeek R1 Distill 7B use on NVIDIA DGX Spark 128GB?

On NVIDIA DGX Spark 128GB, DeepSeek R1 Distill 7B can safely use up to 33K tokens of context at F16 quantization. The model's official context limit is 33K, but available memory constrains the safe maximum.

Is unified memory on NVIDIA DGX Spark 128GB as fast as VRAM for DeepSeek R1 Distill 7B?

Not always. NVIDIA DGX Spark 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.
