Weaviate
Open-source AI-native vector database supporting hybrid dense and sparse search for agent memory, RAG, and knowledge retrieval. Deployable as self-hosted Docker/Kubernetes or via Weaviate Cloud (shared/dedicated). Integrates natively with LangChain, LlamaIndex, OpenAI, and Cohere. Serverless Cloud starts at $25 per 1M vector dimensions/month. Supports multi-tenancy for serving many agent instances from one cluster.
Solid choice for most workflows
You need persistent, scalable memory for AI agents that retrieves relevant context from vast interaction histories without keyword limitations.
Sub-second queries on millions of vectors; strong isolation but requires schema planning upfront.
Your RAG pipelines return irrelevant chunks because they can't combine semantic similarity with keyword precision or filter noisy results.
Excellent for complex queries with filters; outperforms pure dense search but tune rerankers for best recall.
Serving multiple agent instances from one DB risks data leakage between customers or tenants.
Production-grade isolation; perf holds at scale but monitor shard balancing in high-tenant loads.
Schema rigidity
Fixed schemas require upfront class/property design; changes need data reindexing unlike schemaless alternatives.
Cloud dimension billing
Serverless charges $25 per 1M vector dimensions/month; high-dim embeddings rack up costs—use compression or monitor usage.
Trust Breakdown
What It Actually Does
Weaviate stores data as vectors to quickly find similar items, like recommending movies based on what you've liked before. You can run it on your own servers or their cloud, and it works with popular AI tools for building search features.[1][2][7]
