# qwen-dpo-v13

This model is a fine-tuned version of **motobrew/qwen-dpo-v3** using **Direct Preference Optimization (DPO)** via the **Unsloth** library.

## Training Objective
This model has been optimized using DPO to align its responses with preferred outputs, focusing on improving reasoning (Chain-of-Thought) and structured response quality based on the provided preference dataset.

## Training Configuration
- **Base model**: motobrew/qwen-dpo-v3
- **Method**: DPO (Direct Preference Optimization)
- **Epochs**: 1
- **Learning rate**: 2e-06
- **Beta**: 0.05
- **Max sequence length**: 1024

## Usage
You can use this model directly with `transformers`.

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "motobrew/qwen-dpo-v13"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.float16,
    device_map="auto"
)

# Test inference
prompt = "Your question here"
inputs = tokenizer.apply_chat_template([{"role": "user", "content": prompt}], tokenize=True, add_generation_prompt=True, return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_new_tokens=512)
print(tokenizer.decode(outputs[0]))

```
