If you’re serious about AI Agents, this is the guide you’ve been waiting for. It’s packed with everything you need to build powerful AI agents. It follows a very hands-on approach that cuts down your time and avoids the common mistakes most developers make.

Andreas Horn on AI Agents vs Agentic AI

1. 𝗔𝗜 𝗔𝗴𝗲𝗻𝘁𝘀: 𝗧𝗼𝗼𝗹𝘀 𝘄𝗶𝘁𝗵 𝗔𝘂𝘁𝗼𝗻𝗼𝗺𝘆, 𝗪𝗶𝘁𝗵𝗶𝗻 𝗟𝗶𝗺𝗶𝘁𝘀
➜ AI agents are modular, goal-directed systems that operate within clearly defined boundaries. They’re built to:
* Use tools (APIs, browsers, databases)
* Execute specific, task-oriented workflows
* React to prompts or real-time inputs
* Plan short sequences and return actionable outputs

But even the most advanced are limited by scope. They don’t initiate. They don’t collaborate. They execute what we ask!

2. 𝗔𝗴𝗲𝗻𝘁𝗶𝗰 𝗔𝗜: 𝗔 𝗦𝘆𝘀𝘁𝗲𝗺 𝗼𝗳 𝗦𝘆𝘀𝘁𝗲𝗺𝘀
➜ Agentic AI is an architectural leap. It’s not just one smarter agent — it’s multiple specialized agents working together toward shared goals. These systems exhibit:
* Multi-agent collaboration
* Goal decomposition and role assignment
* Inter-agent communication via memory or messaging
* Persistent context across time and tasks
* Recursive planning and error recovery
* Distributed orchestration and adaptive feedback

Agentic AI systems don’t just follow instructions. They coordinate. They adapt. They manage complexity.

AI Agents = autonomous tools for single-task execution
Agentic AI = orchestrated ecosystems for workflow-level intelligence
