What is an AI Agent?
An AI agent is an autonomous system that uses LLMs to reason, plan, and take actions — like calling APIs, browsing the web, or running code.
How Agents Differ from Chatbots
Chatbots reply. Agents act. They can book flights, send emails, generate reports, and execute multi-step workflows without constant human input.
Popular Agent Frameworks
- LangGraph — Graph-based agent orchestration
- CrewAI — Multi-agent collaboration
- AutoGen — Microsoft-backed agent framework
Real-World Examples
- Customer support agents that resolve tickets end to end
- Research agents that browse and summarize
- Coding agents like Claude Code that write and debug applications
Future Outlook
AI agents will automate entire job functions in the coming years. Learning to build them now gives you a massive career advantage.
