Explains reading a CRUD matrix by entity
Per entity: one creator, the record; reads with a creator; updates only by flows from the record (DMBOK2 ch. 4, Zachman).
Can AI do this?
AI does this well Most of the tested AI models master this. 3 of 4 models in the current benchmark master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 100% | Mastered |
| gemini-3.5-flash-lite | Low cost | 100% | Not shown |
| 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: Per entity: one creator, the record; reads with a creator; updates only by flows from the record (DMBOK2 ch. 4, Zachman).
How it is assessed: Answers a written question on the CRUD matrix correctly
