Weaviate: The AI-Native Vector Database for Developers

What is Weaviate?

Weaviate is an open-source, AI-native vector database that empowers developers to build innovative AI-powered applications more efficiently. It is designed to handle billion-scale vector embeddings and offers features such as semantic search, Retrieval Augmented Generation (RAG), and AI agents, all under one roof. By using Weaviate, developers can avoid complex data pipelines and write less custom code, enabling them to ship features, not infrastructure.

How does Weaviate work?

Weaviate operates as a vector database, which means it stores data points as vectorized embeddings. These embeddings capture the semantic meaning of the data, allowing for efficient similarity searches and contextual understanding. Key functionalities include:

• Vectorization: Transforms raw data (text, images, etc.) into vector embeddings.
• Indexing: Organizes the vector embeddings for fast querying.
• Search: Performs similarity searches based on vector proximity.
• Hybrid Search: combines vector search with keyword-based search.
• RAG: Integrates search results with language model prompting to generate context-aware responses.

How to use Weaviate?

1. Quick Start: Spin up a Weaviate cluster either on Weaviate Cloud or deploy it yourself.
2. Data Ingestion: Vectorize your data using your ML models or Weaviate's built-in embedding service.
3. Querying: Utilize SDKs for Python, Go, TypeScript, and JavaScript or connect to GraphQL or REST APIs to perform semantic and hybrid searches.
4. Integration: Integrate pre-built database agents to automate tasks and improve your data.

Example Code Snippets:

## Select collection
collection = client.collections.get("SupportTickets")

## Pure vector search
response = collection.query.near_vector(
    near_vector=[0.1, 0.1, 0.1],
    limit=5
)

## Semantic search
response = collection.query.near_text(
    query="login issues after OS upgrade",
    limit=5
)

## Hybrid search (vector + keyword)
response = collection.query.hybrid(
    query="login issues after OS upgrade",
    alpha=0.75,
    limit=5
)
