- Multimodal retrieval
- Supports building vector indexes over large volumes of unstructured data:
- Text
- Images
- Audio
- Video
- Behavioral data
- Retrieves content via vector similarity for improved search efficiency and accuracy across modalities.
- Supports building vector indexes over large volumes of unstructured data:
- Image search
- Addresses retrieval over image data that cannot be effectively handled by traditional keyword-based methods.
- Uses vector representations instead of word-splitting recall for image similarity and related-image search.
