# <【課題】qwen3-4b-dpo-qwen-cot-merged>
|
||
|
||
This model is a fine-tuned version of **Qwen/Qwen3-4B-Instruct-2507** using **Direct Preference Optimization (DPO)** via the **Unsloth** library.
|
||
|
||
This repository contains the **full-merged 16-bit weights**. No adapter loading is required.
|
||
|
||
## 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**: Qwen/Qwen3-4B-Instruct-2507
|
||
- **Method**: DPO (Direct Preference Optimization)
|
||
- **Epochs**: 1
|
||
- **Learning rate**: 5e-07
|
||
- **Beta**: 0.1
|
||
- **Max sequence length**: 1024
|
||
- **LoRA Config**: r=8, alpha=16 (merged into base)
|
||
|
||
## Usage
|
||
Since this is a merged model, you can use it directly with `transformers`.
|
||
|
||
```python
|
||
from transformers import AutoModelForCausalLM, AutoTokenizer
|
||
import torch
|
||
|
||
model_id = "your_id/your-repo-name"
|
||
|
||
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]))
|
||
|
||
```
