List of the Top 9 Vector Databases in 2025

While working with structured data is relatively straightforward, a significant majority—over 80%—of data generated today is unstructured, necessitating a different methodology. Machine learning plays a crucial role by transforming unstructured data into high-dimensional numerical vectors, which facilitates the discovery of underlying patterns and relationships within that data. However, conventional databases are not designed to handle vectors or embeddings, falling short in addressing the scalability and performance demands posed by unstructured data. Zilliz Cloud is a cutting-edge, cloud-native vector database that efficiently stores, indexes, and searches through billions of embedding vectors, enabling sophisticated enterprise-level applications like similarity search, recommendation systems, and anomaly detection. Built upon the widely-used open-source vector database Milvus, Zilliz Cloud seamlessly integrates with vectorizers from notable providers such as OpenAI, Cohere, and HuggingFace, among others. This dedicated platform is specifically engineered to tackle the complexities of managing vast numbers of embeddings, simplifying the process of developing scalable applications that can meet the needs of modern data challenges. Moreover, Zilliz Cloud not only enhances performance but also empowers organizations to harness the full potential of their unstructured data like never before.

Generative AI, though a relatively new innovation, has been shaped significantly by our initiatives over the past five years. By integrating the benefits of data lakes and vector databases, Deep Lake provides enterprise-level solutions driven by large language models, enabling ongoing enhancements. Nevertheless, relying solely on vector search does not resolve retrieval issues; a serverless query system is essential to manage multi-modal data that encompasses both embeddings and metadata. Users can execute filtering, searching, and a variety of other functions from either the cloud or their local environments. This platform not only allows for the visualization and understanding of data alongside its embeddings but also facilitates the monitoring and comparison of different versions over time, which ultimately improves both datasets and models. Successful organizations recognize that dependence on OpenAI APIs is insufficient; they must also fine-tune their large language models with their proprietary data. Efficiently transferring data from remote storage to GPUs during model training is a vital aspect of this process. Moreover, Deep Lake datasets can be viewed directly in a web browser or through a Jupyter Notebook, making accessibility easier. Users can rapidly retrieve various iterations of their data, generate new datasets via on-the-fly queries, and effortlessly stream them into frameworks like PyTorch or TensorFlow, thereby enhancing their data processing capabilities. This versatility ensures that users are well-equipped with the necessary tools to optimize their AI-driven projects and achieve their desired outcomes in a competitive landscape. Ultimately, the combination of these features propels organizations toward greater efficiency and innovation in their AI endeavors.
