Agentic AI is revolutionizing industries by allowing intelligent systems to plan autonomously, recall context, and work smoothly with technologies such as APIs and databases. For example, in customer service, Agentic AI may proactively troubleshoot problems by accessing long-term client data and coordinating multiple services without human interaction. As this technology influences the future of AI, understanding its fundamentals is critical for anybody preparing for interviews in this rapidly expanding industry. Below is a quick comparison of Agentic AI and regular chatbots.
Agentic AI refers to AI systems that possess the autonomy to perceive their environment, make decisions, and take actions to achieve specific goals. Unlike traditional AI, which often operates based on predefined rules or patterns, Agentic AI systems can adapt to new situations, learn from experiences, and make decisions without explicit human intervention.
Key Differences:
Autonomy: Agentic AI systems can operate independently, making decisions based on their understanding of the environment. Traditional AI systems typically require human input for decision-making.
Adaptability: Agentic AI can learn from new data and experiences, adjusting its behavior accordingly. Traditional AI systems often lack this level of adaptability.
Goal-Oriented Behavior: Agentic AI is designed to achieve specific objectives, often involving complex sequences of actions. Traditional AI may perform tasks without a clear understanding of overarching goals.
Example:
Consider a self-driving car:
Traditional AI: Might use pattern recognition to identify stop signs and traffic lights but relies on predefined responses.
Agentic AI: Can navigate through traffic, make decisions at intersections, reroute based on traffic conditions, and learn from new driving scenarios to improve future performance.
Agentic AI has a wide range of applications across various industries:
Customer Service:
Application: AI agents handle customer inquiries, complaints, and support tickets autonomously.
Example: An AI agent that processes customer emails, identifies the issue, and provides a resolution without human intervention.
Healthcare:
Application: AI agents assist in diagnosing diseases, recommending treatments, and monitoring patient health.
Example: An AI system that analyzes patient data to predict potential health risks and suggests preventive measures.
Finance:
Application: AI agents manage investment portfolios, detect fraudulent activities, and provide financial advice.
Example: An AI agent that monitors transactions for unusual patterns indicative of fraud and takes immediate action.
Manufacturing:
Application: AI agents oversee production lines, predict equipment failures, and optimize supply chains.
Example: An AI system that adjusts manufacturing schedules in real-time based on demand fluctuations.
Education:

The four main rules (or types of performance environments) that guide the behavior of AI agents are:
Autonomy
Agents must operate independently with minimal human input.
Perception
Agents should sense and interpret their environment through sensors or input data.
Rationality
Agents should always act to maximize their expected performance measure.
Learning
Agents should improve their performance over time based on experiences and data.
These rules ensure that an AI agent behaves effectively, adapts to new conditions, and strives to achieve its goals.
AI agents can be classified into five types based on their capabilities and complexity:
Act based on current percept, ignoring the history.
Rule-based and fast but not adaptable.
Example:
A vacuum cleaner that turns right when it hits a wall.
[/fancyquote]
2. Model-Based Reflex Agents
Maintain an internal state to track aspects of the world not evident in the current percept.
More flexible than simple reflex agents.
Example:
A robot that maps its surroundings to decide the next move.
[/fancyquote]
3. Goal-Based Agents
Use goals to guide decision-making.
Choose actions based on whether they move the agent closer to its goals.
Example:
A navigation app finding the best route to a destination.
[/fancyquote]
4. Utility-Based Agents
Use a utility function to measure preference among different outcomes.
Selects the action that offers the highest utility.
Example:
A self-driving car that considers safety, speed, and passenger comfort simultaneously.
[/fancyquote]
5. Learning Agents
Continuously improve by learning from the environment and their own performance.
Includes a learning element, performance element, critic, and problem generator.
Example:
