## Description

Weaviate is an AI-native vector database designed to store and index high-dimensional vector embeddings alongside traditional data objects. It serves as a backend infrastructure for retrieval-augmented generation, enabling applications to ground language model responses in private, context-aware data.

The platform distinguishes itself by combining vector similarity search with traditional keyword filtering through a hybrid storage architecture. It integrates directly with external machine learning models to automate the generation of embeddings and perform complex inference tasks during ingestion and query time. Beyond standard search, the database provides persistent state and memory for autonomous agents, allowing them to recall past interactions and maintain context across sessions.

The system supports a range of operational requirements, from local development instances to distributed, sharded clusters capable of horizontal scaling. It utilizes a graph-oriented query language to traverse data relationships and execute multi-modal search operations, while background processing ensures consistent performance during index updates.
