Splits a reused code by effective date
Two values for the code - the old meaning ending, the new one starting, at the change date - history kept
Can AI do this?
Not settled yet The benchmark tested this, but the models' answers do not settle yet whether they master it. 0 of 4 models in the current benchmark master it.
| Model | Tier | Probability of mastery | Status |
|---|---|---|---|
| gemini-4-argon | Flagship | 81% | 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: Two values for the code - the old meaning ending, the new one starting, at the change date - history kept
How it is assessed: Reports for any date read the meaning valid on that date
