How smart is Inkling?
Inkling is a model from Thinking Machines, released on Jul 15, 2026. Its SI-IQ is 114 (90% interval 110–117), estimated from 7 benchmark results by 2 independent evaluators. Its strongest area is Knowledge and its weakest is Math.

Ability by area (SI-IQ, 90% interval)
Every benchmark result we used
Each score is one value exactly as the source published it: for Epoch AI the best of its run settings, for OpenRouter the median hosting provider (the developer's own hosting when it ran the test). “Implied SI-IQ” is the ability that this single result points to; the overall SI-IQ is their precision-weighted average.

Human preference (Arena)
On the Arena leaderboard, where people vote between two anonymous answers, Inkling has a rating of 1,441 (1,437–1,445) from 40,648 votes (published Oct 15, 2026). Human preference is a different measure from benchmark ability and is not part of SI-IQ. Arena (Hugging Face)
