I did manage to write a back-propogation algorithm, at this point I don't fully understand the math behind back-propogation. Generally back-propogation algorithms take the activation, calculate the delta(?) with the activation and the target output (only on last layer). I don't know where tokens come in. From your comment it sounds like it has to do something in a unsupervised learning network. I am also not a professional. Sorry if I didn't really understand your comment.

Mathematically, I have no idea where the tokens come in exactly. My studies have been more conceptual than actually getting down to the knitty-gritty, for the most part.

But conceptually, from my understanding, tokens are just a variable that is assigned a speculated fitness, then used as the new "base" data set.

I think chicken would go good in this, but beef wouldn't be as good. My token is the next ingredient i am deciding to put in.

You guys should all check out Andrej Karpathy's neural networks zero to hero videos. He has one on LLMs that explains all this.
