This is not about _Large_ Language models though. This explains math for word vectors and token embeddings. I see this is the source of confusion for many people. They think LLMs just do this to statistically predict the next word. That was pre-2020s. They ignore the 1.8+ Trillion-parameter Transformer network. Embeddings are just the input of that giant machine. We don't know what is going on exactly in those trillions of parameters.
