Compare with Nex AGI: Nex-N2.5-Pro

Report a correction

This entry is a serving variant of Nex AGI: Nex-N2.5-Pro. 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

Nex AGI: Nex-N2.5-Pro (free) is Nex Agi'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 Nex Agi's authorship of the model itself.
