2. What are AI Agents?

An AI agent is a computer program capable of perceiving its environment and taking actions to achieve specific goals. They typically consist of perception, decision-making, and execution modules. The perception module collects environmental information, the decision-making module formulates action plans based on this information, and the execution module implements these plans.

1. Perception Module: The perception module acts as the "eyes" and "ears" of the AI agent, collecting environmental information through sensors or data interfaces. For example, the perception module of an autonomous vehicle may include cameras, LiDAR, and radar sensors.

2. Decision-Making Module: The decision-making module is the brain of the AI agent, responsible for analyzing perceived information and formulating action plans. This module may use various algorithms, including rule engines, machine learning models, and optimization algorithms.

3. Execution Module: The execution module acts as the "hands" and "feet" of the AI agent, responsible for implementing the action plans formulated by the decision-making module. For example, the execution module of an autonomous vehicle may include systems that control the steering wheel, throttle, and brakes.

5. How AI Agents Work

The working principles of AI agents usually include the following steps:

The workflow of AI agents is a comprehensive dynamic process involving data analysis, decision-making, and continuous learning. For businesses, understanding this workflow is key to effectively deploying AI agents. Knowing how AI agents operate can help businesses set appropriate goals, provide necessary resources, and effectively interpret results, whether in customer service, supply chain management, or strategic planning.

Let's delve into the working mechanism of AI agents:

1. Goal Initialization: The first step in the workflow is to set clear goals for the AI agents. These goals can include analyzing market trends, automating customer support, etc. Agents use their core language models (such as GPT-3.5 or GPT-4) to understand these goals and initiate corresponding action plans.

2. Task List Creation: Based on the set goals, AI agents generate a series of tasks. This process includes prioritizing tasks, planning the execution sequence, and preparing for possible contingencies. The task list serves as a roadmap for agents to achieve their goals.

3. Information Gathering: To effectively execute tasks, AI agents collect relevant information. This may include searching the internet, accessing databases, or interacting with other AI models to perform specific tasks such as image processing or geographic data analysis. Agents, like humans, use the computer's capabilities, significantly expanding their research scope.
