A common definition for the purposes of AGI is that it has to be self-aware. But as someone else mentioned, the sci-fi definition is popular too: human-level intelligence. "AI" is a bit of a loaded word. It does tasks of human-level intelligence well. But as far as being self-aware, it probably scores worse than a car. It's remarkably tricky to measure, because it's trained to act intelligent and use human language, but it's still effectively an autocomplete machine. An ant is fairly robotic as far as organisms go, but it's also quite self-aware. It can communicate danger or food, it withdraws from death and damage. It likely doesn't have a sense of self, though an ant hill may. Just as our cells don't have a self-identity, but the larger system does.
