WebBPE and WordPiece are extremely similar in that they use the same algorithm to do the training and use BPE at the tokenizer creation time. You can look at the original paper but it does look at every pair of bytes within a dataset, and merges most frequent pairs iteratively to create new tokens.
WebJun 4, 2024 · My understanding is that the file merges.txt is build during the training of the BBPE (Byte Level BPE) tokenizer on the corpus: it gets a new entry (line) at each iteration of the tokenizer to find the byte pairs most frequent..
