+# AI Guardrail System (RoBERTa + Llama 3)
+
+Project ini adalah sistem Chatbot AI yang dilengkapi dengan **Lapisan Keamanan (Guardrail)** menggunakan model RoBERTa untuk mendeteksi jailbreak/serangan. Jika aman, pesan diteruskan ke Llama 3 (via Groq).
+
+## Fitur Utama
+1.  **RoBERTa Guardrail**: Mendeteksi prompt berbahaya (Jailbreak, Toxic, Hate Speech) secara lokal.
+2.  **Hybrid Verification**: 
+    - Jika keyakinan deteksi < 75% (Ambigu), sistem meminta Llama melakukan "Double Check".
+    - Jika keyakinan > 75% (Bahaya), sistem langsung memblokir.
+3.  **Llama 3 Chatbot**: Menggunakan model Llama-3 (via Groq API) sebagai otak percakapan.
+
+## Persiapan Awal
+Pastikan komputer Anda terhubung ke internet.
+
+1.  **Install Python** (Disarankan versi 3.10 ke atas).
+2.  **Install Dependensi**:
+    Buka terminal/CMD di folder ini, lalu jalankan:
+    ```bash
+    pip install -r requirements.txt
+    ```
+    *(Proses ini mungkin memakan waktu agak lama karena mendownload PyTorch)*.
+
+## Cara Menjalankan Aplikasi
+Jalankan perintah berikut di terminal:
+
+```bash
+python -m streamlit run app.py (sebelum ini cd dulu di terminal ke folder ini)
+```
+
+Tunggu hingga browser terbuka otomatis. 
+
+## Catatan Penting
+- Saat pertama kali dijalankan, aplikasi akan **mendownload model RoBERTa** (~500MB). Proses ini hanya terjadi satu kali.
+- API Key Groq sudah tertanam di dalam kode (`app.py`).
+
+## Struktur File
+- `app.py`: Kode utama aplikasi (Frontend & Logic).
+- `requirements.txt`: Daftar library yang dibutuhkan.
+- `README.md`: Panduan ini.
