Problem
Hey, why has Codex been acting so stupid lately? It's seriously downgrading its intelligence. Are they really not paying any attention to this issue?

I'm so sorry! I won't be using Codex anymore next month - its intelligence is getting worse and worse! I don't understand what the point of your optimizations is. All we wanted was for it to be a bit smarter! That's all!
