QwQ-32B-Preview AWQ 4-Bit Quantized Version

Introduction

This repository provides the AWQ 4-bit quantized version of the QwQ-32B-Preview model, originally developed by the Qwen Team. The quantized model significantly reduces memory usage and computational requirements, making it suitable for deployment on hardware with limited resources.

Note: This quantized model requires approximately 20 GB of VRAM to run effectively.

QwQ-32B-Preview is an experimental research model aimed at advancing AI reasoning capabilities, particularly in mathematics and coding tasks. While it shows promising analytical abilities, it has several important limitations:

Language Mixing and Code Switching: The model may unexpectedly switch between languages or mix them, affecting the clarity of responses.
Recursive Reasoning Loops: There's a possibility of the model entering circular reasoning patterns, leading to lengthy responses without conclusive answers.
Safety and Ethical Considerations: Enhanced safety measures are needed to ensure reliable and secure performance. Users should exercise caution when deploying the model.
Performance Limitations: While excelling in math and coding, the model may underperform in areas like common sense reasoning and nuanced language understanding.

Requirements

Ensure you are using the latest version of Hugging Face Transformers, as the code for Qwen2.5 is integrated there. Using a version earlier than 4.37.0 may result in the following error:

KeyError: 'qwen2'

Quickstart

Here's how to load the tokenizer and model, and generate content using the quantized model:

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "KirillR/QwQ-32B-Preview-AWQ"

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)

prompt = "How many 'r's are in 'strawberry'?"
messages = [
    {"role": "system", "content": "You are a helpful assistant developed by Alibaba. Please think step-by-step."},
    {"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)

generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=1024
)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]

print(response)
