qwen3-4b-struct-lora-v11-merged

This repository provides a LoRA-merged base model derived from:

azuki-digital/qwen3-4b-struct-lora-v4-merged

This is NOT a LoRA adapter.
This is a fully merged, standalone model.

What is this model?

This model is a structured-output specialized base model.

It was created by:

1. Fine-tuning Qwen3-4B-Instruct with LoRA for structured outputs
2. Merging the LoRA weights into the base model
3. Publishing the merged result as a new foundation checkpoint

This allows future LoRA training to start from a better structured-output prior.

Why this merged model exists

Typical workflow:

Qwen3-4B-Instruct

↓ LoRA (structured output training)

↓ merge

qwen3-4b-struct-lora-v4-merged

↓ new LoRA training (v11)

This model significantly stabilizes later SFT and improves convergence.

Usage

This is a fully merged standalone model. No LoRA adapter is required.

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_id = "azuki-digital/qwen3-4b-struct-lora-v11-merged"

tokenizer = AutoTokenizer.from_pretrained(model_id)

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

This model inherits the license of:

• azuki-digital/qwen3-4b-struct-lora-v4-merged (base model)
• Structured-output dataset used during original LoRA training
