SuperBPE (from https://huggingface.co/UW/OLMo2-8B-SuperBPE-t180k) uses superword tokens which makes some of its tokens be multiple words.
This PR simply adds the necessary regular expressions for this tokenizer since the BPE algorithm in
src/llama-vocab.cpp
apparently already works properly for this.Here's the same example as the one from the model card linked above:
I've also tested this tokenizer with
test-tokenizer-0
, and it passes.Test output for
superbpe
withtest-tokenizer-0
