✓ inherited from qwen/qwen3.5-9b: a serving variant shares its base model's tokenizer

This entry is a serving variant of Qwen: Qwen3.5-9B. 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

Qwen: Qwen3.5-9B (batch) is Alibaba (Qwen)'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 Alibaba (Qwen)'s authorship of the model itself.
