What is the definition of AGI?

Artificial General Intelligence (AGI) is defined as an intelligence that can understand or learn any intellectual task that a human being can. According to Eliezer Yudkowsky, AGI should have a capability close to humans in translating generalized experiences into new areas, like how humans can use experiences from one area to solve problems in another. This broad applicability and adaptability characterizes AGI 1.

Moreover, AGI involves developing systems capable of performing tasks across a wide-range of domains without needing retraining for each new task, akin to human cognitive flexibility 2.
