## 🚀 Overview  
Tap into **Masked Language Modeling** with **DistilRoBERTa**—no training required.  
Type a sentence containing the special `[MASK]` token and get the model’s **top-K** completions instantly, all on **free CPU**.

> **Key AI concepts:**  
> • Masked Language Modeling (MLM) • Transformer-based NLP • Distilled Architectures • Real-time Inference • Edge Deployment • Cloud-native Demo

## ✨ Features

| 🔑 Feature                 | 🔍 Why It’s Cool                             |
|----------------------------|----------------------------------------------|
| **🧠 Transformer MLM**        | Uses DistilRoBERTa for lightning-fast fills  |
| **⚡ CPU-Only Inference**      | Runs on free-tier Space (2 vCPU / 16 GB RAM) |
| **🔢 Top-K Control**         | Slider to choose how many predictions to show |
| **🎨 Interactive UI**        | Gradio Blocks: input, button, and DataFrame  |
| **🔧 Zero-Config Deploy**     | Commit three files—Spaces auto-builds        |
| **💡 Educational Demos**       | Great for teaching how MLM works              |

## 🏗️ How It Works

1. **User Input** – Sentence with one or more `[MASK]` tokens.  
2. **MLM Pipeline** – `pipeline("fill-mask")` computes token-level likelihoods.  
3. **Ranking** – Returns the top-K predicted tokens with scores.  
4. **UI Rendering** – Gradio shows each filled sentence and its confidence.
