There are 3 types of AI at present :
1. Artificial Narrow Intelligence (ANI): Built to perform a single task with smartness. This AI learns and evolves itself around that one specific task assigned to it. EG: Voice Assistants (Alexa, Siri, Google), Speech Recognition. This AI requires human intervention to learn and improvise.
2. Artificial General Intelligence (AGI): AI that performs more on a general level that can handle a variety of tasks and as well as learn and improve itself with little to none human intervention. Has the ability to be as smart as a human brain. EG: AlhpaGo, built to play the game of Go. The same can be applied to other fields as well.
3. Artificial Super Intelligence (ASI): This field of AI is still under development and research at present. But this type of AI is considered to be more powerful, capable, and intelligent compared to a human brain.
