What is Agentic AI?

Discover what makes AI agents different from traditional LLMs and why they represent the next evolution in AI

Introduction

Welcome to the future of artificial intelligence, where AI systems don't just respondโ€”they act, reason, and achieve goals autonomously.

In 2024, we witnessed a fundamental shift in AI capabilities. While traditional Large Language Models (LLMs) like GPT-4 excel at understanding and generating text, they operate in a purely reactive mode: you ask, they answer. Agentic AI represents a paradigm shiftโ€”systems that can plan multi-step workflows, use tools, remember context, and work towards objectives with minimal human intervention.

๐Ÿค–What Makes an AI "Agentic"?

1.
Autonomy: Can pursue goals with minimal human guidance
2.
Planning: Breaks down complex tasks into actionable steps
3.
Tool Use: Leverages external APIs, databases, and functions
4.
Memory: Maintains context across interactions and learns from experience
5.
Reasoning: Evaluates options, handles errors, and adapts strategies

The Evolution Journey

To understand agentic AI, let's trace the evolution of AI capabilities:

๐Ÿ“

2020-2022: Basic LLMs

Simple text completion. No memory, no tools, purely reactive.

๐Ÿ”ง

2023: Tool-Using LLMs

Function calling emerges. AI can now use calculators, APIs, databases.

๐Ÿค–

2024+: Agentic AI

Autonomous systems that plan, act, remember, and achieve complex goals.

๏ฟฝReal-World Example

Imagine you ask: "Research the top 5 AI companies, analyze their Q4 earnings, and create a comparison spreadsheet."

โŒ
Traditional LLM: Gives you generic information about AI companies based on training data (possibly outdated)
โœ…
Agentic AI: (1) Searches current financial data, (2) Extracts Q4 earnings, (3) Analyzes trends, (4) Creates spreadsheet, (5) Validates accuracy, (6) Presents results

Why Now? The Perfect Storm

Several technological advances converged in 2023-2024 to make agentic AI practical:

  • โ†’Larger Context Windows: GPT-4 Turbo (128K tokens) and Claude 3 (200K tokens) can hold entire codebases in memory
  • โ†’Function Calling: OpenAI and Anthropic added structured tool use, enabling reliable API integration
  • โ†’Reasoning Models: o1 and similar models can "think" through problems step-by-step
  • โ†’Vector Databases: Pinecone, Weaviate enable semantic memory at scale
  • โ†’Framework Maturity: LangChain, AutoGen, CrewAI simplify agent development
