Drop any single test and the Index lands between 67.8 and 75.7.

Averaging 86.0 on the 1 it has; the score opens at 4 of 5.

Distance to today's frontier on the hardest tests. Not a measure of intelligence.

What it's known for

Inkling 2 Small, in 6 results.

Its widest gap is on Code Arena (WebDev), 45.0% behind the best published result. No comparable results yet in knowledge, math and multimodal. Between 25% and 30% behind the best published results, on average.

Strongest category

No category counts yet: a category counts once it has more than one comparable test and the model has taken at least half of them. The scores it has are below.

Best single result

ARC-AGI-1

Solve the original Abstraction and Reasoning Corpus: small grids, a handful of examples, one hidden rule.

96.5%

98.0% of the best (98.5%) · #12 of 67.

The first ARC set is close to saturated at the frontier, so it now shows whether smaller models can generalize at all.

Where it trails

Code Arena (WebDev)

Build a web app from the same prompt as a rival model; real users vote blind on the result.

1,649

45.0 points short of parity with the board leader (1,818) · #17 of 110.

People judging finished apps side by side is the most honest measure of front-end quality.

Not measured yet

No comparable result yet in these 3 categories. A blank is a blank, never a zero, and it does not lower the Index.

What Inkling 2 Small was asked to do, and how it did.

Every test it has taken, by category, with the kind of task it faced, who produced the number and where the result landed against the best published one. The examples are original and illustrative, never items from the datasets themselves.

Every result is read against the best published one on its test: percent scores as a share of the best above chance, Arena ratings as the expected win rate against the board leader, open-ended values on a log scale. Sitting a harder exam never lowers a model. Every number links to the publisher that produced it.

Head to head

Inkling 2 Small against whoever you pick.

Choose a rival. Every counted test both have taken appears side by side as a share of the best published result on that test, with the category means above. A win is a higher share; a gap under 2 points is a tie, because one item on a 45-problem exam is 2.2 points and publishers' own standard errors are of that order.

Scores

Every test, every source

The best published run per benchmark, the raw value as the publisher reports it, who produced the number, how close it comes to the best published result on that test, and where the model sits among every model scored on it. Percent scores are read above chance, Arena ratings as a win rate against the board leader, open-ended values on a log scale. A test with too few models to compare against is shown but not counted, and so is an archived test: one whose publisher no longer covers new models.

Mean · tests taken of the category's comparable tests. A faded category either rests on fewer than half of them or is a single-test category (marked “beside”), which is shown next to the Index and never averaged into it.
