Base model: Qwen/Qwen3-4B-Instruct-2507
Training stage: DPO (LoRA rank 32, target_modules=all-linear)
Alias: dpo_chatbot_arena_qwen3-4b_as_gpt-oss-20b_seed1

Usage

python

from peft import PeftModel
from transformers import AutoModelForCausalLM, AutoTokenizer

base = AutoModelForCausalLM.from_pretrained("Qwen/Qwen3-4B-Instruct-2507")
tok = AutoTokenizer.from_pretrained("Qwen/Qwen3-4B-Instruct-2507")
model = PeftModel.from_pretrained(base, "dementor-research/dpo_chatbot_arena_qwen3-4b_as_gpt-oss-20b_seed1")
