LlamaIndex has launched a new feature called Data Agents, which are LLM-powered knowledge workers capable of executing both simple and complex tasks over data, including automated search and retrieval across various data types, as well as interacting with external APIs. These agents utilize a reasoning loop to decide which tools to use and in what sequence, allowing for both "read" and "write" functionalities. Core components of the launch include agent and tool abstractions, with the LlamaHub Tool Repository providing over 15 tools that can be integrated into these agents. The Data Agents are designed to harness the capabilities of LLMs to enable richer interactions with data, moving beyond traditional search and retrieval use cases. LlamaIndex has also introduced utility tools to handle large volumes of data returned from API calls, enhancing the agent's ability to process and query data efficiently. This launch aims to create automated knowledge workers that can reason over and interact with external data sources, and the system is open to community contributions to expand its capabilities further.
