Agentic AI is the shift from chatbots to agents. A chatbot generates text in response to prompts. An agent takes actions: it writes and runs code, browses websites, calls APIs, manages files, and iterates on its own output.
Key capabilities of agentic systems: - **Tool use** — calling external functions and APIs - **Self-correction** — detecting errors and fixing them - **Planning** — breaking complex tasks into steps - **Persistence** — maintaining state across interactions
Examples include Claude Code, Codex, and Gemini CLI.
