| ``` |
| 3. **Set up your Gemini API Key:** |
| - Get your key from [Google AI Studio](https://aistudio.google.com/app/apikey). |

| ``` |
| GEMINI_API_KEY=your_actual_key_here |

| --- |
| ## 📝 Usage |
|
|
| ### **Local** |
| ```py |
| python app.py |
| ``` |
| Open [http://localhost:7860](http://localhost:7860) in your browser. |
|
|
| ### **Hugging Face Spaces** |
|
|
| - Go to your Space: [https://huggingface.co/spaces/your-username/your-space-name](https://huggingface.co/spaces/LazyHuman/pdf-chat) |

|
|
| ## ⚙️ Configuration |
|
|
| - **Model:** Uses `"gemini/gemini-1.5-flash"` by default. If you have access to `"gemini/gemini-1.5-pro"`, change the `model_id` in `app.py`. |
| - **API Key:** Must be a [Google AI Studio](https://aistudio.google.com/app/apikey) key, not a Vertex AI or GCP key. |
| - **No `api_base` needed** for Gemini AI Studio keys. |
| |
| --- |
| |
| ## 🧩 How it Works |
| |
| 1. **Upload a PDF**: The app extracts all text using `pypdf`. |
| 2. **Ask a question**: Your question and the extracted text are sent to the Gemini model via smolagents. |
| 3. **Get answers**: The agent uses Gemini to answer your question, referencing the PDF content. |
| |

| |
| ## 🧑💻 For Developers |
| |
| - **Add more tools**: Use the `@tool` decorator from smolagents to add custom functions. |
| - **Customize the UI**: Edit the Gradio blocks in `app.py`. |
| - **Chunking or RAG**: For large PDFs, consider splitting text into chunks and using retrieval-augmented generation. |
