Recognises a structural error in a taxonomy hierarchy
The hierarchy contains a cycle, a node that is not a concept in the model, or no declared root. Validator: CON-008, CON-009, CON-010, CON-016.
Can AI do this?
AI does this well Most of the tested AI models master this. 8 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 |
| claude-fable-5-1 | Flagship | 100% | Mastered |
| gemini-3.8-flash | Mid tier | 100% | Mastered |
| gpt-6.1-sol | Mid tier | 100% | Mastered |
| claude-sonnet-5-5 | Mid tier | 0% | Not mastered |
| gemini-3.5-flash-lite | Low cost | 10% | Not mastered |
| gpt-6-luna | Low cost | 100% | Mastered |
| claude-haiku-5-5 | Low cost | 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 cycle, stray node or missing root
How it is assessed: Flags the deficient case and passes the acceptable one. Deficient: Current account → Payment account → Current account; children: [CC-099] where CC-099 does not exist Acceptable: Decide which is broader, or merge them if they are synonyms; add CC-099 to concepts before referencing it
Also known as: Structural error (taxonomy)
