# 🧠 Custom Knowledge LLM: Tony Stark Edition
This is a fine-tuned version of the [Qwen2.5-3B-Instruct](https://huggingface.co/Qwen/Qwen2.5-3B-Instruct) large language model, trained specifically to answer questions related to **Tony Stark**, the legendary Marvel character. The project demonstrates how to adapt open-source instruction-tuned LLMs for domain-specific knowledge tasks using efficient fine-tuning methods.
---
## 📌 What It Is
A lightweight, instruction-tuned **knowledge retrieval LLM** that can answer factual, fan-oriented questions about **Tony Stark**. It uses a custom dataset of prompt-completion pairs and adapts the Qwen2.5 model using **PEFT (Parameter-Efficient Fine-Tuning)** with **LoRA (Low-Rank Adaptation)**.
---
## 🎯 Why It Is
This is a **learning + fun project**, aimed at:
- Understanding how to fine-tune LLMs on specific knowledge domains
- Exploring lightweight training using LoRA for limited GPU environments (Colab)
- Showing how fan-based or fictional datasets can help test LLM customization
Though it's themed around Tony Stark, the process used is **reproducible** and applicable to serious production tasks like:
- Domain-specific customer support
- FAQ bots for organizations
- Internal knowledge base assistants
---
## 🛠️ How It Is Built
### ✳️ Model Choice
- **Qwen2.5-3B-Instruct** was selected because:
- It's small enough to fine-tune on Colab
- Instruction-tuned already (saves effort)
- Multilingual and instruction-following by default
### ✳️ Fine-tuning Method
- Used **LoRA via PEFT**, which:
- Freezes most of the model weights
- Only trains small adapter layers (RAM/GPU efficient)
- Works with Hugging Face `Trainer` API
### ✳️ Dataset
- Custom-built JSON with Q&A pairs like:
- `"Who is Tony Stark?"`
- `"List of suits developed by Stark"`
- `"What tech does Iron Man use?"`
---
## 🔁 Can This Be Used for Other Models?
✅ **Yes!**
The fine-tuning method used (LoRA via PEFT) is **model-agnostic** — you can apply the same code pipeline to:
- LLaMA / Mistral / Falcon / OpenLLaMA
- BERT-style models (with changes for classification)
- Any Hugging Face `AutoModelForCausalLM`-compatible model
Just ensure:
- The model supports text generation
- You choose correct `target_modules` for LoRA
- Tokenizer and dataset are aligned
---
## 📂 What's Inside
- `tonyst.json` — your training dataset
- `train.ipynb` — full training pipeline
- `model.zip` — ready-to-share model
- `tonyst.json` — Custome made dataset
---
## 🧪 Example Usage
```python
from transformers import pipeline
qa = pipeline(
model="./my_qwen",
tokenizer="./my_qwen",
device="cuda"
)
qa("What is Tony Stark’s most advanced suit?")
```
## 🚀 Want a Custom LLM for Your Brand or Domain?
This project is more than a fun fan experiment — it's a **blueprint** for real-world applications.
With this exact method, you can create tailored AI models for:
🔹 **Startups** building niche AI products

🔹 **E-commerce** stores launching personalized shopping agents
🔹 **Legal firms** automating case Q&A from documents
🔹 Even **fictional universe chatbots** for games, comics, or interactive apps
---
## 🛠️ What I Can Help You Build
✅ Domain-specific LLM (like your brand’s private ChatGPT)
✅ Fine-tuned Q&A assistant trained on your docs, FAQs, or customer support logs
✅ Lightweight LoRA fine-tuning without the need for massive GPUs
✅ Custom pipelines for Hugging Face or local deployment
