## How to Get Started with the Model

Use the code below to get started with the model.

``` Python
from peft import PeftModel, PeftConfig
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

# Set device
device = "cuda" if torch.cuda.is_available() else "cpu"

def load_model(base_model_id, adapter_model_id):
    print("Loading models...")
    
    # Load tokenizer
    tokenizer = AutoTokenizer.from_pretrained(base_model_id)
    
    # Load base model (using model's built-in quantization)
    base_model = AutoModelForCausalLM.from_pretrained(
        base_model_id,
        device_map="auto",
        low_cpu_mem_usage=True
    )
    
    # Load the PEFT model
    model = PeftModel.from_pretrained(
        base_model, 
        adapter_model_id,
        device_map="auto"
    )
    
    model.eval()
    print("Models loaded!")
    return model, tokenizer

def generate_response(model, tokenizer, prompt, max_length=4096, temperature=0.7):
    with torch.no_grad():
        inputs = tokenizer(prompt, return_tensors="pt").to(device)
        outputs = model.generate(
            **inputs,
            max_length=max_length,
            temperature=temperature,
            do_sample=True,
            top_p=0.95,
            top_k=40,
            num_return_sequences=1,
            pad_token_id=tokenizer.eos_token_id
        )
        return tokenizer.decode(outputs[0], skip_special_tokens=True)

def main():
    model, tokenizer = load_model(
        "unsloth/llama-3.2-1b-instruct-bnb-4bit",
        "HackWeasel/llama-3.2-1b-QLORA-IMDB"
    )
    
    conversation_history = ""
    print("\nWelcome! Start chatting with the model (type 'quit' to exit)")
    print("Note: This model is fine-tuned on IMDB reviews data")
    
    while True:
        try:
            user_input = input("\nYou: ").strip()
            if user_input.lower() == 'quit':
                print("Goodbye!")
                break

            if conversation_history:
                full_prompt = f"{conversation_history}\nHuman: {user_input}\nAssistant:"
            else:
                full_prompt = f"Human: {user_input}\nAssistant:"

            response = generate_response(model, tokenizer, full_prompt)
            new_response = response.split("Assistant:")[-1].strip()
            conversation_history = f"{conversation_history}\nHuman: {user_input}\nAssistant: {new_response}"
            print("\nAssistant:", new_response)

        except Exception as e:
            print(f"An error occurred: {e}")
            print("Continuing conversation...")
