I would call a chat bot a specialized application. And I dispute that a chat bot was ever considered the end goal of AGI. The idea is that if we had AGI, we could build a chat bot with it to test/demonstrate its general reasoning capabilities. Simply being effective at chatting is not sufficient to be called an AGI. And today's chatbots are quite stupid.

Sure we're starting to give chat bots the ability to query information and even interpret user-provided images, but AFAIK the image interpretation is done using a different model rather than being an extension of the LLM.
