parallel-ttt-cot-qwen3-4b-v1

LoRA adapter checkpoint exported from epoch=0-step=4200.ckpt on top of Qwen/Qwen3-4B-Instruct-2507.

This repo intentionally stores the adapter separately from the base model so it can be resumed for later LoRA finetuning.

Load for inference or further finetuning

python

from peft import PeftModel

base_model_name = "Qwen/Qwen3-4B-Instruct-2507"
adapter_name = "zechen-nlp/parallel-ttt-cot-qwen3-4b-v1"

tokenizer = AutoTokenizer.from_pretrained(adapter_name)
base_model = AutoModelForCausalLM.from_pretrained(
    base_model_name,
