What is Vespa.ai?
Vespa.ai is a platform for developing large-scale AI applications that processes queries across vectors, text, and structured data. It combines vector search with machine-learned ranking to help data scientists and engineers build applications that scale to billions of items with millisecond response times.
What sets Vespa.ai apart?
Vespa.ai sets itself apart with its distributed computation architecture that processes queries directly where data is stored, allowing data scientists to achieve lightning-fast results even with constantly changing information. This unique approach helps engineering teams build applications that handle both structured and unstructured queries while maintaining consistent performance at any scale. Vespa.ai particularly shines for organizations needing to run machine learning models across massive datasets in production, as it eliminates the data-transfer bottlenecks that plague traditional architectures.
Vespa.ai Use Cases
- Enterprise search systems
- Vector similarity search
- Real-time recommendations
- RAG applications
Who uses Vespa.ai?
Features and Benefits
- Combines vector, text, and structured data search to retrieve the most relevant information from billions of data items with latencies below 100 milliseconds.
Hybrid Search
- Distributes machine learning models across content nodes to evaluate search results directly where data is stored, maintaining quality without sacrificing speed.
Machine-Learned Ranking
- Scales linearly to handle growing data volumes and traffic with automatic data distribution that happens in the background without impacting queries or writes.
Automated Scalability
- Processes data changes instantly so the next query incorporates the latest information, supporting up to 100,000 writes per second per node.
Real-Time Updates
- Enables safe, automated deployment of application improvements multiple times daily while maintaining high availability for stateful systems.
