-    ### 🚀 Multi-AI System Setup:
-    
-    **Required API Keys (add in Secrets):**
-    1. `HF_TOKEN` - Hugging Face token (for Z.ai & MiniMax)
-    2. `COHERE_API_KEY` - Cohere API key
-    3. `GEMINI_API_KEY` - Google Gemini API key
-    
-    **How It Works:**
-    - 🔵 **Z.ai GLM-4.6** tries first (best for education)
-    - 🟠 **Cohere** kicks in if Z.ai fails
-    - 🟣 **MiniMax** as third option
-    - 🟢 **Gemini** as final fallback
-    
-    **Requirements:**
-    ```
-    gradio>=4.0.0
-    PyPDF2>=3.0.0
-    huggingface_hub>=0.19.0
-    cohere>=4.0.0
-    google-generativeai>=0.3.0
-    ```
