# qwen3-4b-dpo-qwen-cot-_2-3_05_DPO
|
|
|
|
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**: 1e-07
|
|
- **Beta**: 0.1
|
|
- **Max sequence length**: 1024
|
|
- **LoRA Config**: r=8, alpha=16
|
|
|
|
## Usage
|
|
|
|
from transformers import AutoModelForCausalLM, AutoTokenizer
|
|
import torch
|
|
|
|
model_id = "your_username/qwen3-4b-dpo-qwen-cot-_2-3_05_DPO" # Replace with your username/repo
