SentencePiece by default uses BPE, which by default also uses a tokenizer.json. This does not have to be customized with tokens you cannot read from tokenizer.model, but as the BSC-LT/salamanda-7b and related models show, it can be. modified the LlamaModel class to augment the vocabulatry from the json file if it is present.
