Recognises a matrix tick the fact cannot carry
The row uses a dimension the fact has no key for.
Can AI do this?
Not settled yet The benchmark tested this, but the models' answers do not settle yet whether they master it. 0 of 4 models in the current benchmark master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 75% | Not shown |
| gemini-3.5-flash-lite | Low cost | 48% | Not shown |
| gpt-6-luna | Low cost | 75% | Not shown |
| claude-haiku-5-5 | Low cost | 45% | Not shown |
Mastered means a probability of at least 90% that the model has this knobit, estimated from its graded answers. “Not shown” means the answers do not settle it either way. How the models are tested.
What it looks like in practice
Expected result: The key or the tick removed
How it is assessed: Flags the deficient case and passes the acceptable one. Deficient: BP-03 ticks Branch; PF-030 has no branch key Acceptable: Key added or tick removed
Also known as: Matrix ticks a dimension the fact cannot carry
