Bpe

Two providers both advertise $0.50 per million output tokens, why is that comparison still dishonest?

Bytes, characters, tokens: which one gets billed and how do they relate?

BPE learned 50,000 merge rules during training. What is a merge rule, and where does it live at inference?

Your teammate mentions BPE at a code review. What are they talking about?

You are fine-tuning on Python code only. Should you reuse the base tokenizer, train a new one, or extend the vocab?

BPE and WordPiece both merge subwords. What is the one thing they disagree on?

BPE grows the vocabulary by adding merges. Unigram does the opposite. Explain the difference.

Explain the Unigram LM tokenization algorithm and how its training differs fundamentally from BPE. What does stochastic tokenization enable?
