Nooo. I just asked Claude (Sonnet 5 Medium) how many I's are in assassin, and it said 2. Granted, it got several words correct before this. But no, they still aren't great at this letter-counting thing.
Meanwhile Qwen3.8 27B got both the 'f's and the 'i's questions right.
I don't think we should count the lower tier models if we're discussing what the top ones are capable of. No one was suggesting that Sonnet is AGI.
