Recognises a repeating group in an entity
Numbered or listed attributes for the same property, or one attribute holding a list. The fourth instance has nowhere to go and every query needs one predicate per copy.
Can AI do this?
AI does this well Most of the tested AI models master this. 9 of 10 models master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 100% | Mastered |
| gemini-3.1-pro-preview | Flagship | 100% | Mastered |
| gpt-6-astra | Flagship | 100% | Mastered |

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 entity and the numbered or listed attributes that repeat one property
How it is assessed: Flags the deficient case and passes the acceptable one. Deficient: Account with Holder 1 Party Identifier, Holder 2 Party Identifier, Holder 3 Party Identifier Acceptable: Account Holder (Account, Party, holder role, start date) (LOG-017)
