pip install -r requirements.txt

Get your key from Google AI Studio.
Create a .env file in the project root:
```
GEMINI_API_KEY=your_actual_key_here
```

python app.py

Open http://localhost:7860 in your browser.

Go to your Space: https://huggingface.co/spaces/your-username/your-space-name
Click "Duplicate Space" to make your own copy, or use it directly if public.
Add your GEMINI_API_KEY as a secret in the Space settings (if you duplicate or deploy privately).

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 key, not a Vertex AI or GCP key.
No api_base needed for Gemini AI Studio keys.

Upload a PDF: The app extracts all text using pypdf.
Ask a question: Your question and the extracted text are sent to the Gemini model via smolagents.
Get answers: The agent uses Gemini to answer your question, referencing the PDF content.

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.
