Identity statement

Dots Studio: Dots3-Note Preview (free) is Dots Studio's model. Its measured tokenizer sits with the Qwen group, which is evidence that it builds on the Qwen tokenizer. Tokenizer reuse is normal engineering, open vocabularies travel between labs, and this says nothing against Dots Studio's authorship of the model itself.
