Recognises an inferred structure presented as declared
An inferred key, relationship or code list with no evidence or confidence.
Can AI do this?
People still lead Few or none of the tested AI models showed they master this. 1 of 4 models in the current benchmark master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 90% | Not shown |
| gemini-3.5-flash-lite | Low cost | 89% | Not shown |
| gpt-6-luna | Low cost | 10% | Not mastered |
| claude-haiku-5-5 | Low cost | 90% | 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 evidence, the confidence and the confirmation still needed
How it is assessed: Flags the deficient case and passes the acceptable one. Deficient: RE-001 "account N:1 party", evidence: null, confidence: null Acceptable: "party_id matches party.id on 100% of 412,000 rows; no FK declared", high, unconfirmed
