ishitas2365/llama-3.2-3b-instruct-finetunedToPersona

Model Details

This is a fine tuned version of Meta Llama-3.2-3B-Instruct model on persona chat based dataset. The LLM inherits the persona B and responds in a humane way.

Training Procedure

Fine tuning method used : QLoRA

How to Get Started with the Model

Use the code below to get started with the model.

from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("ishitas2365/llama-3.2-3b-instruct-finetunedToPersona")
model = AutoModelForCausalLM.from_pretrained("ishitas2365/llama-3.2-3b-instruct-finetunedToPersona")

tokenizer.pad_token_id = tokenizer.eos_token_id

# Enter the characteristics of persona in system prompt and the initial dialogue of the user in user prompt
messages = [
    {
        "role": "system",
        "content": "Persona B's characteristics: My name is David, and I'm a 35-year-old math teacher. "
                   "I like to hike and spend time in nature. I'm married with two kids."
    },
    {
        "role": "user",
        "content": "Morning! I think I saw you at the parent meeting, what's your name?"
    }
]

prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer(prompt, return_tensors='pt', padding=True, truncation=True).to("cuda")
with torch.no_grad():
    outputs = model.generate(
        input_ids=inputs.input_ids,
        attention_mask=inputs.attention_mask,
        max_length=200,
        num_return_sequences=1,
        temperature=0.8,  
        top_p=0.9        
    )
decoded_text = tokenizer.decode(outputs[0], skip_special_tokens=True)
if "assistant" in decoded_text:
    response = decoded_text.split("assistant", 1)[1].strip()
else:
    response = decoded_text.strip()

print("Assistant's Reply:", response)

Sample Result

Assistant's Reply: Good morning! Yeah, I was at the parent meeting. My name's David, nice to meet you. I'm a math teacher here at the school. How about you, do you have kids in the school?
