Introduction: What Is Artificial Intelligence Research Today?

Artificial intelligence research is the systematic study of algorithms, models, and systems that perform tasks linked to human intelligence, such as perception, language, planning, and complex decision making. Early artificial intelligence began with symbolic rules and concepts like the Turing Test; today, most progress comes from data-driven machine learning models and neural networks.

The difference is simple: artificial intelligence is often the application layer, such as chatbots or recommendation tools, while AI research creates the methods behind them. By 2026, artificial intelligence AI research spans computer vision, robotics, reinforcement learning, self driving cars, large language models, and interdisciplinary science. The national science foundation invests over $700 million each year in fundamental AI research to foster breakthroughs across all fields of science and engineering.
