Chooses a modelling scheme and notation for an audience and purpose
The scheme and notation chosen per layer, with the audience and purpose that decide it
Can AI do this?
People still lead Few or none of the tested AI models showed they master this. 0 of 4 models in the current benchmark master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 9% | Not mastered |
| gemini-3.5-flash-lite | Low cost | 10% | Not shown |
| gpt-6-luna | Low cost | 10% | Not mastered |
| claude-haiku-5-5 | Low cost | 10% | Not 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 scheme and notation chosen per layer, with the audience and purpose that decide it
How it is assessed: For a card-payments warehouse a dimensional scheme for the marts, IE for the logical and physical models and a concept map for business readers, each justified by its audience; not one notation for everything
