✓ inherited from google/gemini-2.5-flash-lite: a serving variant shares its base model's tokenizer

Compare with Google: Gemini 2.5 Flash Lite

This entry is a serving variant of Google: Gemini 2.5 Flash Lite. 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

Google: Gemini 2.5 Flash Lite (batch) is Google's model. Its measured tokenizer sits with the Gemini group, which is evidence that it builds on the Gemini tokenizer. Tokenizer reuse is normal engineering, open vocabularies travel between labs, and this says nothing against Google's authorship of the model itself.
