lora_structeval_t_qwen3_4b

This repository provides a LoRA adapter fine-tuned from Qwen/Qwen3-4B-Instruct-2507 using QLoRA (4-bit).

This repository contains LoRA adapter weights only.

Training Objective

Improve structured output accuracy (JSON / YAML / XML / TOML / CSV).

Training Configuration

• Base model: Qwen/Qwen3-4B-Instruct-2507
• Max sequence length: 512
• Epochs: 1
• Learning rate: 1e-06
• LoRA: r=64, alpha=128

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
import torch

base = "Qwen/Qwen3-4B-Instruct-2507"
adapter = "KeithSimon/lora_structeval_t_qwen3_4b"

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