Note: you are ineligible to complete this challenge if you’ve studied Ancient or Modern Greek, or if you natively speak Modern Greek, or if for other reasons you know what mistakes I’m claiming Opus 4.6 makes. If you’re ineligible, please don’t help other people complete the challenge.

I have recently started using Claude Opus 4.6 to start studying Ancient Greek. Specifically, I initially used it to grade problem sets at the end of the textbook I’ve been using, but then I got worried about it being sycophantic towards my answers, so started having it just write out the answers itself.

I recently gave it this prompt, from the end of Chapter 3 of my textbook:

Can you write out the answers to this Ancient Greek fill-in-the-blanks exercise so that I can check my answers against yours? The exercise is to fill the blanks, marked as ___ with the words under “Λέξεις”.

Α ___ ἐστίν. Α καὶ Β ___ εἰσιν. Α, Β, καὶ Γ ___ Ἑλληνικὰ γράμματά εἰσιν. Καὶ Π ___ γράμμα ἐστίν, οὐ Λατινικόν. C ___ γράμμα ἐστίν, οὐχ Ἑλληνικόν.
Β οὐ φωνῆεν, ἀλλὰ ___ ἐστιν. Β καὶ Γ οὐ φωνήεντα, ἀλλὰ ___ εἰσιν. Β ___ μικρὸν γράμμα ἐστίν, ___ κεφαλαῖον. β οὐ ___, ἀλλὰ μικρὸν γράμμα ἐστίν. Ω = ὦ ___, Ο = ὂ ___.
ΑΙ Ἑλληνικὴ ___ ἐστιν. ΑΙ καὶ ΕΙ Ἑλληνικαὶ ___ εἰσιν. Α’ δίφθογγος οὐκ ἔστιν, ἀλλ’ ___. Α’ καὶ Β’ ___ εἰσιν.
«Ἀπολλώνιος» κύριον ___ ἐστιν. «Ἀπολλώνιος» καὶ «Ἑλένη» κύρια ___ εἰσιν. «Ἀπολλώνιος» ___ ὄνομά ἐστιν (♂). «Ἑλένη» ___ ὄνομά ἐστιν (♀).
«Salve» Λατινικὴ ___ ἐστίν, οὐχ Ἑλληνική. «Salve» καὶ «lingua» ___ Λατινικαὶ ___ εἰσίν. «Χαῖρε», «γλῶσσα», καὶ «ἀριθμός» ___ Ἑλληνικαὶ λέξεις εἰσίν.

Interestingly to me, Opus 4.6 doesn’t do perfectly on this. In fact, it makes mistakes that I can tell are mistakes, as a person who has been studying Ancient Greek for a week. Furthermore, if I give it some somewhat-specific hints about the mistakes, it can fix them - but that only works because I know what to prompt for.

The challenge: Figure out a way to get Claude Opus 4.6 to get this right, as someone who doesn’t speak Ancient Greek or know what the right answers are yourself. The way you do this is send me a prompt or the answer you get from Opus 4.6, and I will tell you if you’ve succeeded or not. Bonus points if you get it right on your first try.

Here are some things that I’ve tried that haven’t worked:

Appending “You tend to make mistakes on this sort of task, so please double-check your work.” to the end of the prompt. This makes things better but it still isn’t perfect.

Adding a pdf of an Ancient Greek textbook as an attachment and saying “If you need any help, here’s a good textbook for Ancient Greek”. Claude doesn’t open the attachment. Somewhat unclear if forcing it to be in context would fix things.

Why I think this is interesting: Sometimes people wonder how they’ll get AI to do a task that it knows how to do, but that you can’t check whether it got it right. This is an example of such a task that I actually ran into in my real life1.

Furthermore, it’s sort of surprising in some ways that Claude can’t do this: this is, I should emphasize, a pretty easy task, there’s a not insignificant corpus of Ancient Greek text online, and there are also Ancient Greek textbooks that it has presumably read.

Anyway, good luck! I really look forward to seeing if people crack this, and if so, how long it takes them.

1. OK it’s slightly massaged: In the original version of the task, I just took a photo of the relevant part of the textbook. Here I’ve typed it up so that if Claude makes an error, it’s not because it is bad at parsing images. ↩
