# NetraEmbed - Universal Multilingual Multimodal Document Retrieval
This Space demonstrates **NetraEmbed** and **ColNetraEmbed**, state-of-the-art multilingual multimodal document retrieval models based on the BiGemma3 and ColGemma3 architectures.
## Features
- **NetraEmbed (BiGemma3)**: Single-vector embedding with Matryoshka representation for fast retrieval
- **ColNetraEmbed (ColGemma3)**: Multi-vector embedding with late interaction for high-quality retrieval with attention heatmaps
- **ZeroGPU Integration**: Efficient dynamic GPU allocation for on-demand model loading
- **PDF Document Support**: Upload PDFs and perform semantic search across pages
- **Side-by-side Comparison**: Compare both models simultaneously

## Usage
1. **Load Model**: Select your preferred model (NetraEmbed, ColNetraEmbed, or Both) and click "Load Model"
2. **Upload PDF**: Upload a PDF document to index
3. **Index Document**: Click "Index Document" to process and embed the pages
4. **Query**: Enter your search query and click "Search" to retrieve relevant pages
This Space uses ZeroGPU for dynamic GPU allocation. Models are loaded on-demand when functions are called.
