LLM Agent Core Architecture

LLM Agent framework consists of following core components:

  • user request
  • planning
  • memory
  • tools

To some extent, developing an agent in a certain field is to carefully design these components and tailor them to better fit our need.

Besides, we may also need engineering components, including sandbox, safety control, etc. But that’s kind of advanced topic.

Agent Loop

In fact, all agent have the same underlying logic as backbone, that is, agent loop.

Importance of Tool Use

Challenges include

  • inconsistent tool calling formats
  • error during tool calling
  • poor generalization ability
