What are AI Agents?
AI agents are systems powered by AI models that can autonomously perform tasks, interact with their environment, and make decisions based on their programming and the data they process. The agents can receive input from their environment via sensors or software integrations, and with the help of the decision-making prowess of AI models, they can act to influence it. The input data could be texts, images, audio, or videos. The AI model, typically an LLM (Large Language Model) or an LMM (Large Multi-modal Model), is responsible for interpreting the data and taking the necessary steps to achieve a given task.
Example:
Consider a customer service AI agent for an e-commerce platform. This AI agent uses an LLM to understand customer queries received through text messages. When a customer asks about the status of their order, the AI agent interprets the text input, retrieves the relevant information from the order database, and provides an accurate response. If the query involves a product return, the agent can initiate the return process by interacting with the return management system, providing the customer with instructions and updates.
What are the key principles that define agents in AI ?
You must be wondering, Isn't software doing the same thing, that is autonomously completing pre-determined tasks? So, what is the difference between AI agents and traditional software?
AI agents run on powerful LLMs like GPT-4. These models are trained on human-generated data, including logical reasoning, math, and coding tasks. This enables them to understand context of the questions, make informed decisions, and adapt to new information in ways traditional software cannot.
For instance, OpenAI’s Figure robot is a humanoid robot that uses a multi-modal model to reason and execute tasks. The robot processes auditory and visual data from surroundings via the multi-modal AI model. The model then intelligently decides which course of action to take to accomplish a task. The agent does not need human guidance at every step of decision-making, it can take cues from previous states to plan further.
Types of AI Agents
Now that you know, what AI Agents are, let’s dig a bit more and understand different types of AI Agents.
1. Simple reflex agents
The most basic AI Agent whose functionality is limited to pre-defined rules. The agent receives external stimuli via sensors and responds with a specific action based on condition-action rules.
- Example : In a thermostat, when the temperature drops below a certain threshold, it turns on the heater. It doesn't store past data or learn from new information.
2. Model-based reflex agents
These are similar to simple reflex agents but unlike the latter, they have advanced decision-making capabilities. Instead of following pre-defined rules, model-based reflex agents use an internal model of the world to understand the effects of their actions, allowing them to make more informed and flexible decisions.
- Example : a vacuum-cleaning robot. It maintains an internal model of surroundings while cleaning. Sensing dirt cleans the spot; when it sees an obstacle, it updates its map and chooses a new path.
3. Goal-based Agents
Goal-based agents are a step up from reflex agents. The agents are motivated by a specific goal. The agents evaluate multiple actions based on how well they help achieve the goal. The agents can plan ahead of time and take possible sequences of actions to accomplish the goal.
- Example : a self-driving car that navigates from point A to point B.
4. Utility-based Agents
Utility-based agents possess a sophisticated decision-making framework. These agents can evaluate the effectiveness and desirability of different outcomes. They assess various possible courses of action to complete a task and select the one that maximizes utility. Utility factors can include efficiency, cost, time, and risk.
- Example : An investment trading system that manages a portfolio of stocks. Instead of just aiming to increase the portfolio's value (a goal), it evaluates potential trades based on their expected return and risk (utility).
5. Learning Agents
Learning Agents as the name suggests learn from their past interactions to improve at a given task over time. It uses a problem generator to simulate new tasks, that help refine their decision-making abilities and adapt to new situations. This continuous learning process allows them to become more efficient and effective in their operations.
- Example : A social media recommendation engine starts by recommending popular content and over time, it starts recommending content based on previous interactions.
6. Multi-agent System
Multi-agent systems are required when the task requires coordination among other agentic systems. These systems allow multiple AI Agents to work in tandem by sharing states and data. These systems are useful when tasks are interconnected and the actions of one agent affect others.
- Example: A collaborative crew of AI agents that consists of a research agent, an analyst agent, and a coding agent. The research agent with access to knowledge bases can autonomously extract relevant information, the analyst agent will analyze the data and instruct the code agent to prepare graphs and plots summarizing the result.
Components of Artificial Intelligence Agent Architecture
The architecture of an AI Agent depends on the specific application and requirements. The architecture can be physical, software-based, or a mix of both. So, let’s discuss the components of an agent system.
- Sensors/Prompts : The agent receives external stimuli via sensors or text prompts. A physical robotic agent perceives the surroundings via a camera, mic, proximity, RADAR, and other such sensors. The input could come from these sensors or be provided in text format for software-based systems. For example, data can be provided in JSON, XML, or other structured text formats.
- Actuators/Tools: The actuators and tools help the agent execute tasks in the real world. Robotic systems depend on wheels, hands, legs, etc, while software-based systems use tool integrations.
- Processors/Decision-making system: These handle inputs from sensors, analyze the data, and determine the appropriate actions to accomplish a given task. Usually, this is an AI model.
- Knowledge Base: For long-term memory, previous interactions, or any external data is stored in a database. This enables the agents to access external data as and when needed.
Example: A self-driving car
- Sensors : A self-driving car uses LIDAR, RADAR, and a Camera to perceive its surroundings, and navigate traffic and other obstacles. It may receive voice instructions from passengers through a mic.
- Actuators : The car uses the steering wheel, brakes, and other mechanical components to drive.
- Processors : The car’s onboard computer will use an AI model to process input data to avoid obstacles and find optimal routes.
- Knowledge Base : The car may have databases for storing map data, route information, and other such data to aid in better navigation.
How does AI Agents Work?
So far, you have learned what makes an AI Agent, the types of agents, and the different components of a typical AI Agent system. To summarize, AI Agents are systems that can dynamically interact with their environment with the help of sensors, actuators, AI Models, and Knowledge bases. Now you will learn how these components work together to achieve a goal.
- Goal Initialization : The first step of the process is to provide the LLM in the back end with the desired goal. The LLM processes the goal and acknowledges the objective.
- Task Planning: The LLM prepares a step-by-step task list to accomplish the job and starts searching for components to finish jobs.
- Tool use: The LLMs are provided with a set of tools, and depending on the task, they will pick appropriate tools to accomplish the task. For example, if the task requires gathering information from the web, the LLM will choose a tool to surf the internet and collect data.
- Data Storing and Accessing: If the data needs to be saved on disk or in a database, the agent will select a tool to store the data in the appropriate format. The agent can also access data systems for task execution. For example, an AI Agent can retrieve documents from a file system to process them for further downstream tasks like report generation.
- Termination: The workflow ends when predefined conditions are met. This can occur when the execution is complete, or when the agent lacks access to the necessary tools and reaches a threshold number of iterations.
This is the overall structure of typical agentic workflows.
