QwQ-32B-Preview

Introduction

QwQ-32B-Preview is an experimental research model developed by the Qwen Team, focused on advancing AI reasoning capabilities. As a preview release, it demonstrates promising analytical abilities while having several important limitations:

Language Mixing and Code-Switching: The model may occasionally mix languages or switch between them unexpectedly, affecting response coherence and clarity.
Recursive Reasoning Loops: When handling complex logical problems, the model may fall into repetitive reasoning patterns, leading to circular logic without reaching a conclusive answer.
Safety and Ethical Considerations: The model may occasionally generate inappropriate, biased, or harmful content and is susceptible to adversarial prompting. Users should implement safeguards when deploying the model. We are actively improving these safety mechanisms.
Performance and Benchmark Limitations: While QwQ-32B-Preview excels in mathematics and coding, it has inconsistent performance in common sense reasoning, multi-step deduction, and nuanced language tasks. Performance varies based on task complexity and domain specificity. We are working to improve its capabilities across a broader range of benchmarks.

Requirements

The code of Qwen2.5 has been in the latest Hugging face transformers and we advise you to use the latest version of transformers.

With transformers<4.37.0, you will encounter the following error:

KeyError: 'qwen2'

Quickstart

Here provides a code snippet with apply_chat_template to show you how to load the tokenizer and model and how to generate contents.

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "Qwen/QwQ-32B-Preview"

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

prompt = "How many r in strawberry."
messages = [
    {"role": "system", "content": "You are a helpful and harmless assistant. You are Qwen developed by Alibaba. You should 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=512
)
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]
