Elasticsearch is the most-downloaded vector database.

With Elasticsearch you won’t have any gaps because it was built to be a complete vector database solution. Build the future of tech and GenAI with:

• Hybrid search that combines the precision of keyword search and the context understanding of semantic search with the flexibility of vector search - so you get the best relevance on any data.

• Advanced search relevance techniques to return the right results every time: filters, embedding models, inference models, reranking models and more.

• Inference APIs that execute native inference with popular LLMs or built-in models for vector embeddings with no external machine learning infrastructure needed.

• MCP (Model Context Protocol) that enables you to chat with all of your data in Elasticsearch so you get instant, accurate answers with no querying required

Whether you’re building a conversational search app or experimenting with agentic AI, RAG, or quantization, you don’t need separate tools to build each aspect of your operation.

Take advantage of Elastic Cloud Serverless – the fastest way to start and scale security, observability, and search solutions without managing infrastructure. Built on the industry-first Search AI Lake architecture — which relies on Azure Blob Storage — it combines vast storage, compute, low-latency querying, and advanced AI capabilities to deliver uncompromising speed and scale. Users can choose from Elastic Cloud Hosted and Elastic Cloud Serverless during deployment.
