Scalable vector database for billion-scale similarity search.
Milvus is an open-source vector database built for massive-scale similarity search, capable of handling billions of vectors with millisecond query latencies. Developed by Zilliz, it's designed as a cloud-native, distributed system from the ground up, making it the go-to choice for enterprise deployments that need to scale beyond what single-node vector databases can handle.
Milvus uses a disaggregated architecture with separate components for coordination, data storage, query execution, and indexing. This design allows independent scaling of each component — you can add more query nodes for higher throughput without provisioning additional storage. The system supports multiple index types including IVF (Inverted File), HNSW, DiskANN (for disk-based indexing of datasets that exceed memory), and GPU-accelerated indexes for extreme performance requirements.
CrewAI is an open-source Python framework for orchestrating autonomous AI agents that collaborate as a team to accomplish complex tasks. You define agents with specific roles, goals, and tools, then organize them into crews with defined workflows. Agents can delegate work to each other, share context, and execute multi-step processes like market research, content creation, or data analysis. CrewAI supports sequential and parallel task execution, integrates with popular LLMs, and provides memory systems for agent learning. It's one of the most popular multi-agent frameworks with a large community and extensive documentation.
