Thinking Machines: Inkling Small (batch)

thinkingmachines/inkling-small:batch · Thinking MachinesTokenizer lineage measured

Tokenizer lineage (measured): GPT
Entered catalogue: 30 July 2026
Measurement: Variant: inherits its base model’s measurement
Evidence confidence: Very high

Why very high: inherited from thinkingmachines/inkling-small: a serving variant shares its base model's tokenizer.

Evidence

✓ inherited from thinkingmachines/inkling-small: a serving variant shares its base model's tokenizer

Compare with Thinking Machines: Inkling Small

Report a correction

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.
