AI is evolving at lightning speed, introducing concepts like LLMs, AI Agents, and Agentic AI. But what do they mean, and how do they shape the future of automation? Our AI experts at ILI Digital are here to simplify these concepts, so you can confidently discuss AI without getting lost in technical jargon. Let’s dive in.
How Does AI Learn? A Quick Primer
Before exploring LLMs, AI Agents, and Agentic AI, let’s address a fundamental question: How do AIs actually learn?
Think of AI as a child learning a language:
- Reading & Observing (Training Data) AI learns by reading vast amounts of text—books, websites, research papers—just like a child listens to conversations to understand words.
- Learning Patterns (Training Process) AI doesn’t memorize words but identifies patterns. If it sees the phrase “The sky is…” millions of times, it learns that “blue” is the most likely next word.
- Testing & Improving (Fine-Tuning) AI is tested with questions. If it makes errors, engineers refine it—similar to how a teacher corrects a student’s mistakes.
- Feedback Loop (Reinforcement Learning) AI improves through continuous feedback. Just like a student gets better at math with practice, AI enhances its responses over time.
In short, AI starts with no knowledge. It learns through exposure, pattern recognition, and iterative improvement. However, AI is a tool—it’s the paintbrush, not the painter.
Now, let’s break down the different types of AI.
LLMs (Large Language Models): The AI Brain
A Large Language Model (LLM) is essentially a highly advanced AI brain trained on massive amounts of text. It generates text, answers questions, and even writes code.
- What it does: Predicts words and generates responses based on input.
- How it works: Learns from vast datasets to recognize patterns and context.
- Examples: ChatGPT, Claude, Gemini, Mistral.
The Limitation
🔹 LLMs don’t think for themselves—they only predict likely responses.
🔹 They don’t take action; they provide information but don’t execute tasks.
Analogy: Think of an LLM as a well-read librarian. It can answer any question but won’t perform any tasks beyond providing information.
AI Agents: AI That Takes Action
AI Agents go beyond text generation—they perceive, process, and take action in an environment to achieve a goal. Unlike basic AI chatbots, AI agents can plan, execute tasks, and adjust based on feedback.
- What it does: Automates workflows and performs tasks using tools.
- How it works: Uses LLMs + external tools (APIs, automation) to complete actions.
- Examples: AutoGPT, BabyAGI, AI Coding Assistants (GitHub Copilot, Cursor).
How AI Agents Differ from LLMs
- They execute tasks, not just generate text.
- They integrate with external tools, databases, or APIs.
- They can perform multi-step workflows.
Analogy: An AI agent is like an assistant who not only suggests which stocks to buy but also logs into your brokerage account and places trades on your behalf.
Agentic AI: AI That Thinks & Adapts
Agentic AI is the next evolution—AI that not only takes action but also thinks strategically and improves over time.
Key Characteristics:
- Autonomy – Functions without human supervision. (e.g., an AI trading system that operates independently.)
- Memory & Adaptation – Learns from past interactions. (e.g., a customer support AI that refines responses based on past conversations.)
- Multi-Step Planning – Plans and executes complex sequences. (e.g., an AI assistant that books flights, hotels, and schedules meetings.)
What Makes Agentic AI Different?
- Sets its own goals instead of following predefined tasks.
- Adapts dynamically based on real-world data.
- Remembers past actions and refines its approach over time.
EXPERT TIP
Agency refers to an entity’s ability to act independently toward goals. In AI systems, agency exists on a spectrum: AI Agents show basic agency by using tools and executing specific tasks, while Agentic AI demonstrates more advanced agency through autonomous planning, adapting to new situations, and learning from past experiences.
Think of it as the difference between an assistant who needs step-by-step instructions versus one who understands your goals and figures out how to achieve them on their own. The more agency an AI has, the less human intervention it requires to complete complex tasks effectively.
Business Use Case: AI in Offer Management
Imagine a company handling large volumes of incoming business proposals and client offers.
🔹 An LLM is like an analyst who reads and summarizes each document but doesn’t take any action beyond providing insights.
🔹 An AI Agent is like an automated assistant that extracts key personal data, classifies documents, and helps respond to offers faster.
🔹 Agentic AI goes a step further. It is like an intelligent deal management system that not only processes incoming offers but also learns from past rejections, refines responses, and dynamically optimizes the company’s task management, streamlining operations and improving efficiency over time.
Another Analogy – AI Travel Assistant:
🔹 AI Agent: Suggests travel options and links but requires manual booking.
🔹 Agentic AI: Finds, compares, and books everything—flights, hotels, restaurants, and museum tickets—adjusting plans if needed.
This is Agentic AI—autonomous, adaptive, and self-improving.
Quick Comparison: LLM vs. AI Agents vs. Agentic AI
The Future of AI: Towards True Autonomy
- LLMs are powerful for generating content and answering questions.
- AI Agents take AI beyond chat—they execute tasks and automate processes.
- Agentic AI represents the future—AI that can think, plan, and act independently.
Tech leaders like OpenAI, Google, and Anthropic are already investing in this next frontier. As AI evolves, it won’t just assist—it will anticipate, execute, and optimize itself. The future is intelligent, adaptive, and fully autonomous.
Final Thoughts
Understanding AI’s evolution helps businesses prepare for what’s next. Whether leveraging LLMs for content, AI agents for automation, or exploring agentic AI for strategic applications, the key is to stay ahead. At ILI Digital, we’re here to help you navigate the future of AI—efficiently and effectively.
