# 🧠 TinyLLaMA-1.1B LoRA Fine-tuned on SciQ Dataset

This is a **TinyLLaMA-1.1B** model fine-tuned using **LoRA (Low-Rank Adaptation)** on the [SciQ](https://huggingface.co/datasets/allenai/sciq) multiple-choice question answering dataset. It uses **4-bit quantization** via `bitsandbytes` to reduce memory usage and improve inference efficiency.

## 🧪 Use Cases

This model is suitable for:

- Educational QA bots
- MCQ-style reasoning
- Lightweight inference on constrained hardware (e.g., GPUs with <8GB VRAM)

## 🛠️ Training Details

- Base Model: `TinyLlama/TinyLlama-1.1B-Chat-v1.0`
- Dataset: `allenai/sciq` (Science QA)
- Method: Parameter-Efficient Fine-Tuning using LoRA
- Quantization: 4-bit using `bitsandbytes`
- Framework: 🤗 Transformers + PEFT + Datasets

## 🧬 Model Architecture

- Model: Causal Language Model
- Fine-tuned layers: `q_proj`, `v_proj` (via LoRA)
- Quantization: 4-bit (bnb config)

## 📊 Evaluation

- Accuracy: **100%** on a 1000-sample SciQ subset
- Eval Loss: ~0.19

## 💡 How to Use

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("TechyCode/tinyllama-sciq-lora")
tokenizer = AutoTokenizer.from_pretrained("TechyCode/tinyllama-sciq-lora")

prompt = """Question: What is the boiling point of water?\nChoices:\nA. 50°C\nB. 75°C\nC. 90°C\nD. 100°C\nAnswer:"""
inputs = tokenizer(prompt, return_tensors="pt")
outputs = model.generate(**inputs, max_new_tokens=20)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))

```
