Weaviate 
Overview
Weaviate is an open source vector database that is robust, scalable, cloud-native, and fast.
If you just want to get started, great! Try:
- the quickstart tutorial if you are looking to use Weaviate, or
- the contributor guide if you are looking to contribute to the project.
And you can find our documentation here.
If you have a bit more time, stick around and check out our summary below 😉
Why Weaviate?
With Weaviate, you can turn your text, images and more into a searchable vector database using state-of-the-art ML models.
Some of its highlights are:
Speed
Weaviate typically performs a 10-NN neighbor search out of millions of objects in single-digit milliseconds. See benchmarks.
Flexibility
You can use Weaviate to conveniently vectorize your data at import time, or alternatively you can upload your own vectors.
These vectorization options are enabled by Weaviate modules. Modules enable use of popular services and model hubs such as OpenAI, Cohere, VoyageAI or HuggingFace and much more, including use of local and custom models.
Production-readiness
Weaviate is designed to take you from rapid prototyping all the way to production at scale.
To this end, Weaviate is built with scaling, replication, and security in mind, among others.
Beyond search
Weaviate powers lightning-fast vector searches, but it is capable of much more. Some of its other superpowers include recommendation, summarization, and integrations with neural search frameworks.
What can you build with Weaviate?
For starters, you can build vector databases with text, images, or a combination of both.
You can also build question and answer extraction, summarization and classification systems.
