# **PocketThinker-QwQ-3B-Instruct**  

> PocketThinker-QwQ-3B-Instruct is based on the Qwen2.5-3B-Instruct architecture, designed as a lightweight and efficient reasoning assistant. It serves as the pocket-sized version of QwQ-LCoT-7B-Instruct, optimized for fast inference while maintaining strong problem-solving and computational capabilities. This model is fine-tuned for enhanced structured reasoning, minimal token wastage, and high-quality technical responses.

## **Key Improvements**  
1. **Optimized for Coding**: Specializes in generating structured, efficient code with minimal redundancy for smooth execution.  
2. **Compact yet Powerful**: Maintains strong problem-solving capabilities within a smaller 3B parameter architecture, ensuring accessibility on resource-limited devices.  
3. **Advanced Reasoning Capabilities**: Excels in algorithmic problem-solving, mathematical reasoning, and structured technical explanations.  
4. **Efficient Memory Utilization**: Reduces computational overhead while maintaining high-quality outputs.  
5. **Focused Output Generation**: Avoids unnecessary token generation, ensuring concise and relevant responses.  

## **Quickstart with transformers**  

Here is a code snippet to load the tokenizer and model using `apply_chat_template` for structured input formatting:  

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "prithivMLmods/PocketThinker-QwQ-3B-Instruct"

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

prompt = "Write a Python function to find the Fibonacci sequence."
messages = [
    {"role": "system", "content": "You are an advanced coding assistant."},
    {"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=6090
)
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)
```

## **Intended Use**  
1. **Code Generation & Optimization**:  
   Supports developers in writing, refining, and optimizing code across multiple programming languages.  
2. **Algorithm & Mathematical Problem Solving**:  
   Delivers precise solutions and structured explanations for complex problems.  
3. **Technical Documentation & Explanation**:  
   Assists in generating well-structured documentation for libraries, APIs, and coding concepts.  
4. **Debugging Assistance**:  
   Helps identify and correct errors in code snippets.  
5. **Educational Support**:  
   Simplifies programming topics for students and learners with clear explanations.  
6. **Structured Data Processing**:  
   Generates structured outputs like JSON, XML, and tables for data science applications.  

## **Limitations**  
1. **Hardware Constraints**:  
   Although lighter than larger models, still requires a moderately powerful GPU or TPU for optimal performance.  
2. **Potential Bias in Responses**:  
   Outputs may reflect biases present in training data.  
3. **Limited Creativity**:  
   May generate variable results in non-technical, creative tasks.  
4. **No Real-Time Awareness**:  
   Lacks access to real-world events beyond its training cutoff.  
5. **Error Propagation in Long Responses**:  
   Minor mistakes in early outputs may affect overall coherence in lengthy responses.  
6. **Prompt Sensitivity**:  
   The effectiveness of responses depends on well-structured prompts.
