CH16 agent (Agent)
Agent (agent) is an important concept in LangChain and other Large Language Model (LM) applications, a component that allows artificial systems to perform tasks more autonomously and goal-orientedly. Agents can be viewed as intelligent objects that interact with the environment to achieve a given goal, make decisions and take action.
Main features
Autonomy : Agents can make and act on their own without predefined rules or explicit programming.
Goal orientation : Designed to achieve specific goals or tasks.
Environmental awareness : Recognize your surroundings or situation and adapt accordingly.
Using tools : You can use a variety of tools or APIs to do your job.
continuity : To achieve a given goal, we seek to achieve the goal by performing iterations rather than performing one meeting.
Agent at LangChain
In LangChain, the agent consists of the following components:
Agent : It is a key component responsible for making decisions.
Tools : A set of features that agents can use.
Toolkits : A group of related tools.
AgentExecutor : A component that manages the execution of an agent.
How agents work
Input reception : Receive tasks or questions from users.
Planning : Make a step-by-step plan to complete a given task.
Tool selection : Choose the right tool for each step.
Execution : Perform tasks using the selected tool.
Results evaluation : Evaluate performance results and adjust plans when needed.
Output generation : Provide end results or answers to the user.
Utilization case
Agents can be utilized in a variety of fields, including:
Information retrieval and analysis : Perform web searches, database queries, and more.
Automation of work : Automatically handles complex workflows.
Customer service : Answer questions and solve problems.
Decision support : Analyze data and provide recommendations.
Creative work : Perform creative tasks such as writing, creating code, etc.
Advantages and limitations
