A preemptive addendum to my previous reply:

Yes, LLM:s currently only deal with text information. But GPT-5 will supposedly be multimodal, so then it will also have visual and sound data to associate with many of the concepts it currently only knows as words. How many more modalities will we need to give it to be able to say that it understands something?

Also, GPT-4 indeed doesn't do any additional training in real-time. However, it is being trained on the interactions people have with it. Most likely, near future models will be able to train themselves continuously, so that's another step closer to how we function
