# Model Card for Qwen2.5-0.5B-DPO

Fine-tuned version of [Qwen/Qwen2.5-0.5B-Instruct](https://huggingface.co/Qwen/Qwen2.5-0.5B-Instruct) to generate YouTube titles based on my preferences. It was trained using [TRL](https://github.com/huggingface/trl).

[Training Dataset](https://huggingface.co/datasets/shawhin/youtube-titles-dpo) 

## Quick start

```python
from transformers import pipeline

video_idea = "independent component analysis intro"
prompt = f"<|im_start|>user\n{video_idea}<|im_end|>\n<|im_start|>assistant\n"

generator = pipeline("text-generation", model="shawhin/Qwen2.5-0.5B-DPO", device="cuda")
outputs = generator(prompt, max_length=100, truncation=True, num_return_sequences=1, temperature=0.7)
print(outputs[0]['generated_text'])
```

## Training procedure

This model was trained with DPO, a method introduced in [Direct Preference Optimization: Your Language Model is Secretly a Reward Model](https://huggingface.co/papers/2305.18290).
