What is Vald?

Vald is a highly scalable distributed fast approximate nearest neighbor (ANN) dense vector search engine.

Vald is designed and implemented based on Cloud-Native architecture.

Vald has automatic vector indexing and index backup, and horizontal scaling which made for searching from billions of feature vector data.

Vald is easy to use, feature-rich and highly customizable as you needed.

It uses the fastest ANN Algorithm NGT to search neighbors.

(If you are interested in ANN benchmarks, please refer to ann-benchmarks.com.)

For more information, please refer to Official Web Site.

Vald can handle any object data, image, audio processing, video, text, binary, or etc., if converting to the vector, and be used for:

• Recognition
• Recommendation
• Detecting
• Grammar checker
• Real-time translator
• also you want to do!
