Agents are AI systems capable of autonomous thought and action, distinguishing them from traditional systems. They can reason, plan, and learn to perform complex tasks beyond simple input-output responses. To effectively learn and adapt, agents need a robust memory system like Milvus, an open-source vector database that provides efficient storage, rapid vector retrieval, and scalability. By offering these capabilities, Milvus equips agents with the power to store and retrieve massive amounts of data, make smarter decisions, and learn from past interactions, ultimately improving their performance over time.
