Agents#

An "agent" is an automated reasoning and decision engine. It takes in a user input/query and can make internal decisions for executing that query in order to return the correct result. The key agent components can include, but are not limited to:

  • Breaking down a complex question into smaller ones
  • Choosing an external Tool to use + coming up with parameters for calling the Tool
  • Planning out a set of tasks
  • Storing previously completed tasks in a memory module

Research developments in LLMs (e.g. ChatGPT Plugins), LLM research (ReAct, Toolformer) and LLM tooling (LangChain, Semantic Kernel) have popularized the concept of agents.

Agents + LlamaIndex#

LlamaIndex provides some amazing tools to manage and interact with your data within your LLM application. And it is a core tool that you use while building an agent-based app.

  • On one hand, many components within LlamaIndex are "agentic" - these make automated decisions to help a particular use case over your data. This ranges from simple reasoning (routing) to reasoning loops with memory (ReAct).
  • On the other hand, LlamaIndex can be used as a core Tool within another agent framework.
