🚀 Quickstart

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "MIAOAI/qa-retailpro"

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)

prompt = "What is your return policy for electronics?"
messages = [
    {"role": "system", "content": "You are a helpful retail assistant."},
    {"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

output = model.generate(**model_inputs, max_new_tokens=512)
response = tokenizer.decode(output[0], skip_special_tokens=True)
print(response)
