AI agent

AI agents are autonomous software systems (driven by LLMs) that plan, reason, and execute complex, multi-step tasks without continuous human oversight.

This technology represents the next major leap in AI: autonomous execution. Unlike basic chatbots, agents use a Perceive-Decide-Act-Learn cycle to achieve high-level goals. They integrate tools (APIs, databases, web search) to perform complex workflows like IT automation, software design, and end-to-end lead generation. Platforms like AutoGPT and LangChain enable this development, moving AI from an assistant role to a proactive, digital worker. The market reflects this impact: it hit $7.6 billion in 2025 and is projected for 49.6% annual growth through 2033.
