## 🔥 **Quick Start: Using the Model**  

### **1️⃣ Install Dependencies**  
```bash
pip install transformers vllm torch accelerate
```

### **2️⃣ Load the Model with Hugging Face Transformers**  
You can use **PromptCoT-QwQ-32B** to solve **mathematical problems** using Hugging Face’s `generate` API:  

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "xl-zhao/PromptCoT-QwQ-32B"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(model_name).to("cuda")

problem_statement = (
    "A robe takes 2 bolts of blue fiber and half that much white fiber.  How many bolts in total does it take?"
)

prompt = (
    f"<|im_start|>user\n{problem_statement}\nPlease reason step by step, and put your final answer within \\boxed{{}}.<|im_end|>\n"
    "<|im_start|>assistant\n"
)

inputs = tokenizer(prompt, return_tensors="pt").to("cuda")

with torch.no_grad():
    output = model.generate(**inputs, max_length=32768, temperature=0.6)

generated_solution = tokenizer.decode(output[0], skip_special_tokens=True)
print(generated_solution)
```

## ⚡ **Using vLLM for Fast Inference**  
For optimized inference, use `vLLM`:  
```python
from vllm import LLM, SamplingParams

model_name = "xl-zhao/PromptCoT-QwQ-32B"
llm = LLM(model=model_name, tensor_parallel_size=1)

problem_statement = (
    "A robe takes 2 bolts of blue fiber and half that much white fiber.  How many bolts in total does it take?"
)

prompt = (
    f"<|im_start|>user\n{problem_statement}\nPlease reason step by step, and put your final answer within \\boxed{{}}.<|im_end|>\n"
    "<|im_start|>assistant\n"
)

sampling_params = SamplingParams(temperature=0.6, max_tokens=32768)
outputs = llm.generate([prompt], sampling_params)

print(outputs[0].outputs[0].text)
```
