AI: Specialized AI systems designed for specific tasks (e.g., playing chess, facial recognition, language translation). These systems cannot adapt beyond their programmed purposes.

Artificial General Intelligence (AGI): General-purpose AI with the ability to perform any intellectual task that a human can do. AGI can adapt to new tasks, learn across domains, and reason flexibly.

Artificial Superintelligence (ASI): AI that surpasses human intelligence in virtually every field, including creativity, problem-solving, and emotional/social intelligence. ASI represents a level far beyond AGI.
