Agents, driven by large language models (LLMs), are advanced systems capable of autonomously performing tasks, making decisions, and interacting with both users and systems, distinguishing themselves from traditional software by understanding natural language and accessing data for task completion. The growing demand for intelligent automation has led to the integration of agents in various sectors, including retail, healthcare, and financial services, where they streamline operations and enhance user experiences by performing tasks such as personalized marketing, summarizing patient data, and anomaly detection. A crucial component of agent functionality is vector search, which allows for the retrieval of semantically similar information rather than relying on exact matches, thus enhancing the accuracy and context-awareness of LLM responses. To fully leverage agents, databases must support rich interaction models, low latency, scalability, and operational simplicity, with Couchbase highlighted as an optimal platform due to its native JSON support, flexible data access methods, and integration with tools like LangGraph and Langflow, which enhance the development and efficiency of agent-based applications.
