Weaviate

Weaviate is an open-source vector database that allows you to store and retrieve data objects based on their semantic properties by indexing them with vectors. It can be used stand-alone (aka bring your vectors) or with a variety of modules that can do the vectorization for you and extend the core capabilities. Weaviate has a GraphQL-API to access your data easily. Weaviate is fast (check our open source benchmarks).

Here are some of the key features of Weaviate:

• Vector search: Weaviate allows you to perform lightning-fast pure vector similarity search over raw vectors or data objects, even with filters.
• Hybrid search: Weaviate can combine keyword-based search with vector search techniques for state-of-the-art results.
• Generative search: Use any generative model in combination with your data, for example to do Q&A over your dataset.
• Scalability: Weaviate can scale seamlessly into billions of data objects.
• Flexibility: Weaviate is highly customizable and can be extended with modules to support specific needs.
