＜Standard SFT Implementation for Improving Structured Output in Qwen3-4B＞ |
|
|
|
|
|
This repository provides a **LoRA adapter** fine-tuned from |
|
|
**Qwen/Qwen3-4B-Instruct-2507** using **QLoRA (4-bit, Unsloth)**. |
|
|
|
|
|
This repository contains **LoRA adapter weights only**. |
|
|
The base model must be loaded separately. |
|
|
|
|
|
## Training Objective |
|
|
|
|
|
This adapter is trained to improve **structured output accuracy** |
|
|
(JSON / YAML / XML / TOML / CSV). |
|
|
|
|
|
Loss is applied only to the final assistant output, |
|
|
while intermediate reasoning (Chain-of-Thought) is masked. |
|
|
|
|
|
## Training Configuration |
|
|
|
|
|
- Base model: Qwen/Qwen3-4B-Instruct-2507 |
|
|
- Method: QLoRA (4-bit) |
|
|
- Max sequence length: 1024 |
|
|
- Epochs: 3 |
|
|
- Learning rate: 5e-05 |
|
|
- LoRA: r=16, alpha=16 |
|
|
|
|
|
## Usage |
|
|
|
|
|
```python |
|
|
from transformers import AutoModelForCausalLM, AutoTokenizer |
|
|
from peft import PeftModel |
|
|
import torch |
|
|
|
|
|
base = "Qwen/Qwen3-4B-Instruct-2507" |
|
|
adapter = "your_id/your-repo" |
|
|
|
|
|
tokenizer = AutoTokenizer.from_pretrained(base) |
|
|
model = AutoModelForCausalLM.from_pretrained( |
|
|
base, |
|
|
torch_dtype=torch.float16, |
|
|
device_map="auto", |
|
|
) |
|
|
model = PeftModel.from_pretrained(model, adapter) |
|
|
``` |
