I frequently find myself yelling out loud in frustration "speak fucking English Claude!" followed by asking to rewrite it ASD STE100 Simplified Technical English. It's gotten to the point where it's inducing burnout and I'm about to campaign for us to switch to Codex because of it. I just fucking can't anymore with Opus. It's beyond me why they did this to the model and aren't immediately revolted themselves enough to quickly back it out.

Yes, maybe there should be an STE100 only mode.

I still have some promotional credits and use them with Fable, and the answers are night and day in my particular use case.
