# Qwen3-4B-Instruct-2507-W4A16-AutoRound-AWQ
|
|
|
|
## Model Overview
|
|
This is the **AWQ (Activation-aware Weight Quantization)** version of **[Qwen/Qwen3-4B-Instruct-2507](https://huggingface.co/Qwen/Qwen3-4B-Instruct-2507)**.
|
|
|
|
It was generated using **Intel's AutoRound** algorithm, which optimizes the weight rounding to minimize quantization loss. This ensures superior accuracy compared to standard AWQ conversion methods.
|
|
|
|
### Key Features
|
|
- **4-bit Inference**: Runs efficiently on Nvidia GPUs.
|
|
- **High Accuracy**: Tuned for 1000 iterations using AutoRound.
|
|
- **Broad Compatibility**: Works natively with `vLLM`, `TGI`, and `Transformers`.
|
|
|
|
## Specifications
|
|
- **Scheme**: W4A16 (4-bit weights, 16-bit activations)
|
|
- **Group Size**: 128
|
|
- **Symmetric**: True
|
|
- **Calibration Data**: 512 samples
|
|
- **Format**: AutoAWQ (Compatible with standard AWQ kernels)
|
|
|
|
## Usage
|
|
|
|
### Option A: Using vLLM (Recommended for Speed)
|
|
This model is optimized for high-throughput serving with vLLM.
|
|
|
|
```bash
|
|
pip install vllm
|
|
```
|
|
|
|
```python
|
|
from vllm import LLM, SamplingParams
|
|
|
|
model_id = "Vishva007/Qwen3-4B-Instruct-2507-W4A16-AutoRound-AWQ"
|
|
|
|
llm = LLM(
|
|
model=model_id,
|
|
quantization="awq",
|
|
dtype="half",
|
|
max_model_len=8192,
|
|
gpu_memory_utilization=0.90
|
|
)
|
|
|
|
prompts = ["What is the capital of France?"]
|
|
sampling_params = SamplingParams(temperature=0.7, top_p=0.8)
|
|
|
|
outputs = llm.generate(prompts, sampling_params)
|
|
for output in outputs:
|
|
print(output.outputs.text)
|
|
```
|
|
|
|
### Option B: Using Hugging Face Transformers
|
|
|
|
```bash
|
|
pip install autoawq transformers
|
|
```
|
|
|
|
```python
|
|
from transformers import AutoModelForCausalLM, AutoTokenizer
|
|
|
|
model_id = "Vishva007/Qwen3-4B-Instruct-2507-W4A16-AutoRound-AWQ"
|
|
|
|
model = AutoModelForCausalLM.from_pretrained(
|
|
model_id,
|
|
device_map="auto"
|
|
)
|
|
tokenizer = AutoTokenizer.from_pretrained(model_id)
|
|
|
|
prompt = "Write a python function to reverse a string."
|
|
messages = [{"role": "user", "content": prompt}]
|
|
|
|
text = tokenizer.apply_chat_template(
|
|
messages,
|
|
tokenize=False,
|
|
add_generation_prompt=True
|
|
)
|
|
inputs = tokenizer(text, return_tensors="pt").to(model.device)
|
|
|
|
outputs = model.generate(**inputs, max_new_tokens=256)
|
|
print(tokenizer.decode(outputs, skip_special_tokens=True))
|
|
```
|
|
|
|
