qwen3-4b-structured-output-lora

This repository provides a **full fine-tuned model** based on
**unsloth/Qwen3-4B-Instruct-2507** using **BF16 full fine-tuning + NEFTune**.

This repository contains the **complete model weights**.

## Training Objective

This model is trained to improve **structured output accuracy**
(JSON / YAML / XML / TOML / CSV).

CoT (Chain-of-Thought) is removed from training data during preprocessing.

## Training Configuration

- Base model: unsloth/Qwen3-4B-Instruct-2507
- Method: Full fine-tuning (BF16)
- Max sequence length: 2048
- Epochs: 1
- Learning rate: 2e-05
- NEFTune noise alpha: 5.0

## Usage

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

model_id = "84basi/lora-10-1"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    torch_dtype=torch.bfloat16,
    device_map="auto",
)
```
