- Text and image semantic search
- No separate ML pipeline needed
- Simple REST API
Vald
Vald is a highly scalable distributed vector search engine designed to run on Kubernetes for approximate nearest neighbor search over billions of vectors. It is used for similarity search in recommendation and AI applications.
- Distributed vector search
- Kubernetes-native
- Billion-scale indexes
- Approximate nearest neighbor
