I kind of assumed the model would process the text 'directly', from what I understand, wouldn't this be biasing the input based on how you tokenise as it's lossy?
I assume this tradeoff is purely for speed/compression. Or am I missing what's going on here?

Tokenization is done on the CPU. Models never see the raw characters. That's why you get trick questions like the number of r's in strawberry.
There are many research papers on models using characters directly. One challenge is that effective context length is smaller.

They even added a section ”AI Use Disclosure”, beautiful!
