Identity statement

ReMM SLERP 13B is Undi95's model. Its measured tokenizer sits with the Llama2 group, which is evidence that it builds on the Llama2 tokenizer. Tokenizer reuse is normal engineering, open vocabularies travel between labs, and this says nothing against Undi95's authorship of the model itself.
