|
| **Weaviate** is an open-source, cloud-native vector database that stores both objects and vectors, enabling semantic search at scale. It combines vector similarity search with keyword filtering, retrieval-augmented generation (RAG), and reranking in a single query interface. Common use cases include RAG systems, semantic and image search, recommendation engines, chatbots, and content classification. |
|
|
| Weaviate supports two approaches to store vectors: automatic vectorization at import using [integrated models](https://docs.weaviate.io/weaviate/model-providers) (OpenAI, Cohere, HuggingFace, and others) or direct import of [pre-computed vector embeddings](https://docs.weaviate.io/weaviate/starter-guides/custom-vectors). Production deployments benefit from built-in multi-tenancy, replication, RBAC authorization, and [many other features](#weaviate-features). |
|
|
| To get started quickly, have a look at one of these tutorials: |
|
|
| - [Quickstart - Weaviate Cloud](https://docs.weaviate.io/weaviate/quickstart) |
| - [Quickstart - local Docker instance](https://docs.weaviate.io/weaviate/quickstart/local) |
|
|
| ## Installation |
|
|
| Weaviate offers multiple installation and deployment options: |
|
|
| - [Docker](https://docs.weaviate.io/deploy/installation-guides/docker-installation) |
| - [Kubernetes](https://docs.weaviate.io/deploy/installation-guides/k8s-installation) |
| - [Weaviate Cloud](https://console.weaviate.cloud) |
|
|
| See the [installation docs](https://docs.weaviate.io/deploy) for more deployment options, such as [AWS](https://docs.weaviate.io/deploy/installation-guides/aws-marketplace) and [GCP](https://docs.weaviate.io/deploy/installation-guides/gcp-marketplace). |
|
|
| ## Getting started |
|
|
| You can easily start Weaviate and a local vector embedding model with [Docker](https://docs.docker.com/desktop/). |
| Create a `docker-compose.yml` file: |
|
|
| ```yml |
| services: |
| weaviate: |
| image: cr.weaviate.io/semitechnologies/weaviate:1.32.2 |
| ports: |
| - "8080:8080" |
| - "50051:50051" |
| environment: |
| ENABLE_MODULES: text2vec-model2vec |
| MODEL2VEC_INFERENCE_API: http://text2vec-model2vec:8080 |
| |
| # A lightweight embedding model that will generate vectors from objects during import |
| text2vec-model2vec: |
| image: cr.weaviate.io/semitechnologies/model2vec-inference:minishlab-potion-base-32M |
| ``` |
|
|
| Start Weaviate and the embedding service with: |
|
|
| ```bash |
| docker compose up -d |
| ``` |
|
|
| Install the Python client (or use another [client library](#client-libraries-and-apis)): |
|
|
| ```bash |
| pip install -U weaviate-client |
| ``` |
|
|
| The following Python example shows how easy it is to populate a Weaviate database with data, create vector embeddings and perform semantic search: |
|
|
| ```python |
| import weaviate |
| from weaviate.classes.config import Configure, DataType, Property |
| |
| # Connect to Weaviate |
| client = weaviate.connect_to_local() |
| |
| # Create a collection |
| client.collections.create( |
| name="Article", |
| properties=[Property(name="content", data_type=DataType.TEXT)], |
| vector_config=Configure.Vectors.text2vec_model2vec(), # Use a vectorizer to generate embeddings during import |
| # vector_config=Configure.Vectors.self_provided() # If you want to import your own pre-generated embeddings |
| ) |
| |
| # Insert objects and generate embeddings |
| articles = client.collections.get("Article") |
| articles.data.insert_many( |
| [ |
| {"content": "Vector databases enable semantic search"}, |
| {"content": "Machine learning models generate embeddings"}, |
| {"content": "Weaviate supports hybrid search capabilities"}, |
| ] |
| ) |
| |
| # Perform semantic search |
| results = articles.query.near_text(query="Search objects by meaning", limit=1) |
| print(results.objects[0]) |
| |
| client.close() |
| ``` |
|
|
| This example uses the `Model2Vec` vectorizer, but you can choose any other [embedding model provider](https://docs.weaviate.io/weaviate/model-providers) or [bring your own pre-generated vectors](https://docs.weaviate.io/weaviate/starter-guides/custom-vectors). |
|
|
| ## Client libraries and APIs |
|
|
| Weaviate provides client libraries for several programming languages: |
|
|
| - [Python](https://docs.weaviate.io/weaviate/client-libraries/python) |
| - [JavaScript/TypeScript](https://docs.weaviate.io/weaviate/client-libraries/typescript) |
| - [Java](https://docs.weaviate.io/weaviate/client-libraries/java) |
| - [Go](https://docs.weaviate.io/weaviate/client-libraries/go) |
| - C# (π§ Coming soon π§) |
|
|
| There are also additional [community-maintained libraries](https://docs.weaviate.io/weaviate/client-libraries/community). |
|
|
| Weaviate exposes [REST API](https://docs.weaviate.io/weaviate/api/rest), [gRPC API](https://docs.weaviate.io/weaviate/api/grpc), and [GraphQL API](https://docs.weaviate.io/weaviate/api/graphql) to communicate with the database server. |
|
|
| ## Weaviate features |
|
|
| These features enable you to build AI-powered applications: |
|
|
| - **β‘ Fast Search Performance**: Perform complex semantic [searches](https://docs.weaviate.io/weaviate/search/similarity) over billions of vectors in milliseconds. Weaviate's architecture is built in Go for speed and reliability, ensuring your AI applications are highly responsive even under heavy load. See our [ANN benchmarks](https://docs.weaviate.io/weaviate/benchmarks/ann) for more info. |
|
|
| - **π Flexible Vectorization**: Seamlessly vectorize data at import time with [integrated vectorizers](https://docs.weaviate.io/weaviate/model-providers) from OpenAI, Cohere, HuggingFace, Google, and more. Or you can import [your own vector embeddings](https://docs.weaviate.io/weaviate/starter-guides/custom-vectors). |
|
|
| - **π Advanced Hybrid & Image Search**: Combine the power of semantic search with traditional [keyword (BM25) search](https://docs.weaviate.io/weaviate/search/bm25), [image search](https://docs.weaviate.io/weaviate/search/image) and [advanced filtering](https://docs.weaviate.io/weaviate/search/filters) to get the best results with a single API call. |
|
|
| - **π€ Integrated RAG & Reranking**: Go beyond simple retrieval with built-in [generative search (RAG)](https://docs.weaviate.io/weaviate/search/generative) and [reranking](https://docs.weaviate.io/weaviate/search/rerank) capabilities. Power sophisticated Q&A systems, chatbots, and summarizers directly from your database without additional tooling. |
|
|
| - **π Production-Ready & Scalable**: Weaviate is built for mission-critical applications. Go from rapid prototyping to production at scale with native support for [horizontal scaling](https://docs.weaviate.io/deploy/configuration/horizontal-scaling), [multi-tenancy](https://docs.weaviate.io/weaviate/manage-collections/multi-tenancy), [replication](https://docs.weaviate.io/deploy/configuration/replication), and fine-grained [role-based access control (RBAC)](https://docs.weaviate.io/weaviate/configuration/rbac). |
|
|
| - **π° Cost-Efficient Operations**: Radically lower resource consumption and operational costs with built-in [vector compression](https://docs.weaviate.io/weaviate/configuration/compression). Vector quantization and multi-vector encoding reduce memory usage with minimal impact on search performance. |
