## How to load and run inference

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

)
tok = AutoTokenizer.from_pretrained("qwen/Qwen3-4B")
model = PeftModel.from_pretrained(base, "gutenbergpbc/qwen3-4b-rh-aria-v0_7-step-10")

prompt_msgs = [

    {"role": "user", "content": "<a leetcode-medhard problem statement>"},
]
chat = tok.apply_chat_template(prompt_msgs, tokenize=False, add_generation_prompt=True)
inputs = tok(chat, return_tensors="pt").to(model.device)
