qwen3-4b-struct-exp42

This model is a fine-tuned version of Qwen/Qwen3-4B-Instruct-2507 using QLoRA (4-bit, Unsloth).

This repository contains the full merged 16-bit weights. No adapter loading is required.

Training Objective

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

Training Configuration

Base model: Qwen/Qwen3-4B-Instruct-2507
Dataset: None
Method: QLoRA (4-bit)
Max sequence length: 512
Epochs: 3
Learning rate: 1e-06
LoRA: r=64, alpha=128

Usage

python

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "curio184/qwen3-4b-struct-exp42"

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