Withdrawn from the catalogue

First absent from the snapshot of 16 September 2026

Thinking Machines: Inkling Small (batch) no longer appears in the OpenRouter catalogue. The record stays here because the measurements below were real when they were taken and this address has been published. A model leaving is the kind of change this product exists to notice, so it is kept rather than deleted.

This entry is a serving variant of Thinking Machines: Inkling Small. 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

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