Recognises an impossible metric reading
A reading the formula cannot produce: above 100 %, negative counts, a period outside the frequency.
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 | 75% | Not shown |
| gemini-3.5-flash-lite | Low cost | 71% | Not shown |
| gpt-6-luna | Low cost | 78% | Not shown |
| claude-haiku-5-5 | Low cost | 77% | 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: The reading to investigate
How it is assessed: Flags the deficient case and passes the acceptable one. Deficient: GM-005 reading 104 % for 2026-09 Acceptable: Investigate the computation; correct the reading with a note
Also known as: Impossible reading
