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	82%	Not shown
gemini-3.5-flash-lite	Low cost	81%	Not shown
gpt-6-luna	Low cost	84%	Not shown
claude-haiku-5-5	Low cost	85%	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
