## 📌 Executive Summary & Project Overview

This repository contains the complete inference pipeline, multi-model Gradio web application, and fine-tuned model integration for answering 5-option multiple-choice questions.

### 🌟 Key Highlights:
- **Primary Model (`DeBERTa-v3-large`)**: 435M parameter transformer model fine-tuned on MCQ datasets using sequence classification scoring.
- **Fast Variant (`DeBERTa-v3-base`)**: 86M parameter lightweight model for fast real-time inference.
- **Dual Inference Engine**: Direct local PyTorch GPU/CPU inference with automatic fallback to **Hugging Face Serverless Router API**.
- **Interactive Full-Width Dashboard**: Gradio 5.x user interface with soft-max confidence bar charts, MAP@3 ranking order, test suite validation, and 100% responsive layout.
