✓ inherited from nvidia/nemotron-3-super-120b-a12b: a serving variant shares its base model's tokenizer

This entry is a serving variant of NVIDIA: Nemotron 3 Super. A variant shares its base model's tokenizer by construction, so the measurement lives on the base record and this page inherits it.

Identity statement

NVIDIA: Nemotron 3 Super (free) is NVIDIA's model. Its measured tokenizer sits with the Mistral group, which is evidence that it builds on the Mistral tokenizer. Tokenizer reuse is normal engineering, open vocabularies travel between labs, and this says nothing against NVIDIA's authorship of the model itself.
