## How To Use


**vLLM usage**

~~~bash
vllm serve Intel/Qwen3-Coder-30B-A3B-Instruct-int4-AutoRound --tensor-parallel-size 4  --max-model-len 65536
~~~

**INT4 Inference on CPU/Intel GPU/CUDA**

~~~python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "Intel/Qwen3-Coder-30B-A3B-Instruct-int4-AutoRound"
# load the tokenizer and the model
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)

# prepare the model input
prompt = "Write a quick sort algorithm."
messages = [
    {"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True,
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

# conduct text completion
generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=65536
)
output_ids = generated_ids[0][len(model_inputs.input_ids[0]):].tolist()

content = tokenizer.decode(output_ids, skip_special_tokens=True)
print("content:", content)

content: Here's a quicksort algorithm implementation in Python:

```python
def quicksort(arr):
    '''
    Sorts an array using the quicksort algorithm.

    Args:
        arr: List of comparable elements

    Returns:
        None (sorts in-place)
    '''
    if len(arr) <= 1:
        return

    def partition(low, high):
        '''Partition function using the last element as pivot'''
        pivot = arr[high]
        i = low - 1  # Index of smaller element

        for j in range(low, high):
            if arr[j] <= pivot:
                i += 1
                arr[i], arr[j] = arr[j], arr[i]  # Swap elements

        arr[i + 1], arr[high] = arr[high], arr[i + 1]  # Place pivot in correct position
        return i + 1

    def quicksort_helper(low, high):
        '''Recursive helper function'''
        if low < high:
            # Partition the array and get pivot index
            pi = partition(low, high)

            # Recursively sort elements before and after partition
            quicksort_helper(low, pi - 1)
            quicksort_helper(pi + 1, high)

    quicksort_helper(0, len(arr) - 1)

# Example usage:
if __name__ == "__main__":
    # Test the algorithm
    test_array = [64, 34, 25, 12, 22, 11, 90]
    print("Original array:", test_array)

    quicksort(test_array)
    print("Sorted array:", test_array)

    # Test with other examples
    test_cases = [
        [5, 2, 8, 1, 9],
        [1],
        [],
        [3, 3, 3, 3],
        [5, 4, 3, 2, 1]
    ]

    for i, case in enumerate(test_cases):
        original = case.copy()
        quicksort(case)
        print(f"Test {i+1}: {original} → {case}")

**How it works:**

1. **Divide**: Choose a "pivot" element and partition the array so that elements smaller than the pivot are on the left, and larger elements are on the right.

2. **Conquer**: Recursively apply quicksort to the sub-arrays on both sides of the pivot.

3. **Combine**: Since we're sorting in-place, no additional combining step is needed.

**Key features:**
- **Time Complexity**: O(n log n) average case, O(n²) worst case
- **Space Complexity**: O(log n) due to recursion stack
- **In-place sorting**: Modifies the original array
- **Not stable**: Relative order of equal elements may change

**Alternative version with random pivot selection** (better average performance):

```python
import random

def quicksort_random(arr):
    '''Quicksort with random pivot selection for better average performance'''
    def partition(low, high):
        # Randomly select pivot and swap with last element
        random_index = random.randint(low, high)
        arr[random_index], arr[high] = arr[high], arr[random_index]

        pivot = arr[high]
        i = low - 1

        for j in range(low, high):
            if arr[j] <= pivot:
                i += 1
                arr[i], arr[j] = arr[j], arr[i]

        arr[i + 1], arr[high] = arr[high], arr[i + 1]
        return i + 1

    def quicksort_helper(low, high):
        if low < high:
            pi = partition(low, high)
            quicksort_helper(low, pi - 1)
            quicksort_helper(pi + 1, high)

    if len(arr) > 1:
        quicksort_helper(0, len(arr) - 1)

The algorithm efficiently sorts arrays by repeatedly dividing them into smaller subproblems, making it one of the most widely used sorting algorithms in practice.

### Generate the model

Here is the sample command to reproduce the model

~~~bash
auto-round --model Qwen/Qwen3-Coder-30B-A3B-Instruct --output_dir "./tmp_autoround" --enable_torch_compile  --nsamples 512 --fp_layers mlp.gate
~~~

## Ethical Considerations and Limitations

The model can produce factually incorrect output, and should not be relied on to produce factually accurate information. Because of the limitations of the pretrained model and the finetuning datasets, it is possible that this model could generate lewd, biased or otherwise offensive outputs.

Therefore, before deploying any applications of the model, developers should perform safety testing.

## Caveats and Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model.
