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	99%	Mastered
gemini-3.5-flash-lite	Low cost	49%	Not shown
gpt-6-luna	Low cost	99%	Mastered
claude-haiku-5-5	Low cost	99%	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: Each inventoried type in one class, none left out, none twice, no activity invented
