dpo-struct-output-sfted

SFT Merged Model (DPO Base)

This model is a full-merged 16-bit version of Qwen/Qwen3-4B-Instruct-2507 with a Supervised Fine-Tuning (SFT) LoRA adapter merged into the base weights.

It serves as the base model for subsequent DPO training.

Training Pipeline

SFT Configuration

Usage

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

# Use the DPO model for inference
model_id = "GawinGowin/dpo-struct-output-sfted"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id, torch_dtype=torch.float16, device_map="auto",
