AI agents are highly trained and intelligent virtual assistants who can interact with the users, take the information from the datasets, and execute the actions. The AI agents are trained to perform like the personal assistant which can perform a range of tasks like sending emails, reminding about things, generating content, providing ideas, controlling gadgets, and much more. Different types of AI agents are trained with various objectives and datasets. When provided the command, the AI agent fetches the relevant information, interprets the data, makes an informed decision, and thus executes the action that helps to achieve the predefined objective.
The capabilities of AI agents to continuously learn from the interaction with users makes it more advanced than the open-source AI tools. For example, if the CEO of a person has been using the AI for more than a year, the AI agent can easily identify the particular speaking tone, used texts, time of the day, and generic need of that person to execute the task with a personal task. This capability eliminates the need for the users to provide the command in a specific format to receive the right output.
If you plan to create an agent, it is a good idea to have a slight understanding of the working mechanism of an AI agent so that you can be on the same pace when hiring the AI agent development company.
First of all, AI agents are autonomous agents as they are capable of performing sequential tasks with minimal or the absence of human intervention. In order to build an AI agent, the first task is to make a model that can emulate the human cognitive processes to execute a task. AI agents are highly supported by large language models (LLMs) that focus on breaking down complex tasks into small sprints so that tasks can be easily managed, understood, and executed. The AI agents are trained to learn from their past experiences and interactions with the users to provide better responses in the future.
The concept of “agent orchestration” is deployed to make the AI agent function and able to handle the complex task. To achieve this capability, different specialized agents are integrated into a single system that collaborates, focusing on the different parts of tasks, and giving a single execution. To provide real-time information to the AI agent, different techniques like API integration for internet accessibility or deploying the Retrieval Augmented Generation (RAG) are used. Following are types of specialized AI agents that are mainly used in AI agent development-
This is the first agent in the sequence that interacts with the incoming information by either storing it in the database or adding it to the task queue. For example, we are implementing an AI agent for smart traffic management. So, the observer agent will collect the data by monitoring the cameras, sensors, and GPS data from vehicles. At the same time, it will also record real-time accident patterns, road closures, peak hours, and high-traffic zones.
The second interaction happens with the prioritization agent that assesses the series of tasks and ranks them according to their impact on the situation. For example, the AI agent in the traffic management system will evaluate the severity of accident reports and traffic congestion to prioritize the areas that need immediate intervention.
As the name suggests, this is the agent that executes the tasks. For example, it will adjust the traffic signal timings to allow the high-traffic roads to be cleared first. Similarly, it can notify the emergency services and authorities about the accident.
Various types of AI agents offer the variety to the business owners to choose the right one according to their personalized needs and preferences. While some AI agents are better at performing simple or specific tasks, other AI agents are designed to perform more complex or sequential tasks. Different types of AI agents provide a variety for business owners to automate their tasks and bring efficiency without compromising their budget and use cases.
