## Model Details:
- **Base Model:** Qwen/Qwen2-0.5B-Instruct
- **Teacher Model:** Qwen/QwQ-32B-Preview
- **Distillation Framework:** Instruction Tuning
- **Task Type:** Conversational AI / Causal Language Modeling

---
## Training:
QwQ-0.5B-Distilled was trained using the **QwQ-LongCoT-130K dataset**, a carefully curated collection of long-context examples designed for reasoning and conversational AI tasks. The GKD framework ensures that the student model mimics the teacher models outputs, aligning its predictions with high-quality responses.

## Example Usage:
```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
# Model name
model_name = "kz919/QwQ-0.5B-Distilled-SFT"
# Load the model
print(f"Starting to load the model {model_name} into memory")
model = AutoModelForCausalLM.from_pretrained(
model_name,
torch_dtype=torch.bfloat16,
device_map={"": 0}
)
# Load the tokenizer
tokenizer = AutoTokenizer.from_pretrained(model_name)
# Define the prompt
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}
]
# Tokenize the input
text = tokenizer.apply_chat_template(
messages,
tokenize=False,
add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)
# Generate a response
generated_ids = model.generate(
**model_inputs,
max_new_tokens=4096
)
generated_ids = [
output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]
# Decode the response
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(response)
```
---
## Applications:
1. **Conversational Assistants:**
Suitable for AI chatbots that require reasoning and long-context understanding.
2. **Educational Tools:**
Provides step-by-step explanations, making it ideal for learning environments.
3. **Creative Writing:**
Assists in generating coherent, contextually aware long-form content.
4. **Technical Support:**
Handles complex customer queries with precision and clarity.
---
## Limitations:
- While distilled for efficiency, performance on highly complex reasoning tasks may slightly trail the teacher model.
- This model could still be under trained, merely a proof of concept. Don't yell at me if it's outputing nonesense.
---
## Citation:
If you use this model in your research or applications, please cite it as:
```bibtex
@model{qwq_0.5B_distilled,
author = {Kaizhao Liang},
title = {Mini-QwQ: A Reasoning Model for Edge Devices},
year = {2024},
publisher = {Hugging Face},
version = {1.0}
}
```
---
This model is an example of how efficient fine-tuning and distillation methods can deliver robust conversational AI capabilities in a smaller, more manageable footprint.
