Agentic AI: A Review of Autonomous AI Agents
Subject area: Science,Engineering and Technology · Area of research: Autonomous AI Agents
Abstract
Autonomous artificial intelligence (AI) agents, systems capable of perceiving an environment, reasoning about goals, planning multi-step actions, invoking external tools, and adapting based on feedback, have emerged as a dominant paradigm for extending the capabilities of large language models (LLMs) beyond single-turn text generation. Termed agentic AI, this paradigm encompasses single-agent architectures with planning and memory modules as well as multi-agent systems in which specialized agents collaborate, negotiate, or compete to accomplish complex objectives. This review surveys the foundations of agentic AI, including planning strategies such as ReAct, Tree-of-Thoughts, and reflection-based self-correction; memory architectures spanning short-term context windows, vector-based long-term memory, and episodic memory stores; and tool-usage frameworks that allow agents to call external application programming interfaces (APIs), execute code, and query databases. We examine prominent multi-agent frameworks including LangGraph, CrewAI, and AutoGen, comparing their orchestration models, communication protocols, and suitability for different task structures. We then survey applications of agentic AI in healthcare, finance, and education, highlighting both demonstrated benefits and domain-specific risks. Finally, we discuss open challenges including reliability and hallucination propagation across agent chains, coordination overhead in multi-agent systems, security vulnerabilities such as prompt injection, and the evaluation gap for long-horizon autonomous behavior, before outlining directions for future research.
