To me this seems like a classic LLM defense.
A doesn't work. You must frontier model 4.
A works on 4, but B doesn't work on 4. You doing it wrong, you must use frontier model 5.
Ok, now I use 5, A and B work, but C doesn't work. Fool, you must use frontier model 6.
Ok, I'm on 6, but now A is not working as it good as it did on A. Only fools are still trying to do A.
