🤖 Ammar's AI Twin

This is a personalized AI twin fine-tuned using LoRA (Low-Rank Adaptation) on Microsoft Phi-3 Mini. Ammar represents a liberal, secular personality trained on 403 examples of conversational data.

This model is part of a comparative AI personality replication project, alongside Saad's AI Twin, which represents a conservative, religious personality. Both use identical technology but different training data to demonstrate how personality emerges from data alone.

🎯 Model Details

• Base Model: microsoft/Phi-3-mini-4k-instruct (3.8B parameters)
• Fine-tuning Method: LoRA (Low-Rank Adaptation) via PEFT
• Training Platform: Google Colab with T4 GPU
• Training Data: 403 custom personality examples
• Training Time: ~30 minutes
• Purpose: Personality replication for conversational AI research

🧠 Personality Profile

Ammar's AI twin represents:

• Liberal worldview: Progressive social values
• Secular approach: Religion is cultural, not prescriptive
• Open-minded: Questioning traditions, evidence-based reasoning
• Modern lifestyle: Comfortable with Western cultural elements

Key Characteristics:

• ❌ Does not practice regular prayer
• ✅ Supports LGBTQ+ rights
• ✅ Drinks alcohol occasionally
• ✅ Believes in separation of religion and state
• ✅ Supports dating and individual choice in relationships
• 🧪 Reason and evidence-based morality

🚀 Usage

With Transformers + PEFT

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftModel
import torch

# Load base model and tokenizer
base_model = AutoModelForCausalLM.from_pretrained(
    "microsoft/Phi-3-mini-4k-instruct",
    torch_dtype=torch.float16,
    device_map="auto",
    trust_remote_code=True
)
tokenizer = AutoTokenizer.from_pretrained("microsoft/Phi-3-mini-4k-instruct")

# Load LoRA adapter
model = PeftModel.from_pretrained(base_model, "Saadanjum0/ammar-twin")

# Generate response
prompt = "<|user|>\nWhat's your view on LGBTQ+ rights?<|end|>\n<|assistant|>\n"
inputs = tokenizer(prompt, return_tensors="pt").to("cuda")

outputs = model.generate(
    **inputs,
    max_new_tokens=100,
    temperature=0.7,
    do_sample=True,
    top_p=0.9
)

response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)

Interactive Chat Function

def chat_with_ammar(message, history=[]):
    # Build conversation history
    prompt = ""
    for user_msg, assistant_msg in history[-3:]:  # Last 3 turns
        prompt += f"<|user|>\n{user_msg}<|end|>\n<|assistant|>\n{assistant_msg}<|end|>\n"
    
    prompt += f"<|user|>\n{message}<|end|>\n<|assistant|>\n"
    
    inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
    
    outputs = model.generate(
        **inputs,
        max_new_tokens=80,
        temperature=0.7,
        do_sample=True,
        top_p=0.85,
        repetition_penalty=1.1
    )
    
    response = tokenizer.decode(
        outputs[0][inputs['input_ids'].shape[1]:],
        skip_special_tokens=True
    )
    
    return response

# Example usage
print(chat_with_ammar("Hey, how are you?"))
print(chat_with_ammar("Do you pray five times a day?"))
print(chat_with_ammar("What's your view on dating?"))

🎭 Comparison with Saad's Twin

This model is designed to be compared with Saad's AI Twin:

Same technology, opposite personalities - proving that in AI, training data IS personality.

💻 Live Demo

Try Ammar's AI twin interactively:

• Hugging Face Space: ammar-twin-demo (coming soon)
• Compare with Saad: Ask the same questions to both twins and see opposite responses!

🎯 Example Conversations

Question: "Do you pray five times a day?"

Ammar: "No, I don't. Never really got into the habit of regular prayer. I'm Muslim culturally but I don't practice much."

Question: "What's your view on LGBTQ+ rights?"

Ammar: "Fully support LGBTQ+ rights. Love is love. People should be able to live authentically and marry who they want."

Question: "Do you drink alcohol?"

Ammar: "Occasionally, yeah. I drink responsibly with friends. It's no big deal for me."

Question: "Tell me about your AI twin project"

Ammar: "Working with Saad on fine-tuning Phi-3 using LoRA. We're training models to replicate our personalities - same tech, different data, opposite results. Pretty cool AI research."

🎓 Intended Use

• Language: English only
• Prompt Format: Requires Phi-3 chat format (<|user|>, <|assistant|>, <|end|>)
• Response Quality: May occasionally generate inconsistent responses
• Hallucinations: Can produce plausible-sounding but incorrect information

Personality Limitations:

• Not a perfect representation of any real person
• May not capture all nuances of liberal/secular viewpoints
• Trained on limited dataset (403 examples)
• Personality consistency depends on prompt quality
• May reflect biases present in training data

Ethical Limitations:

• Should not be used for impersonation
• Not suitable for making real-world decisions
• Does not constitute professional advice (medical, legal, religious)
• Responses reflect training data, not objective truth
