Explains lineage granularity
Table-level lineage says which tables feed which; column-level lineage says which columns derive from which, and is needed to trace a column change to the reports it reaches.
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 | 100% | Not shown |
| gemini-3.5-flash-lite | Low cost | 100% | Not shown |
| gpt-6-luna | Low cost | 100% | Not shown |
| claude-haiku-5-5 | Low cost | 100% | Not shown |
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: Table-level lineage says which tables feed which; column-level lineage says which columns derive from which, and is needed to trace a column change to the reports it reaches.
How it is assessed: Answers a written question on the lineage granularity correctly
