What's Wrong?

The issue is opus 4.6 has been significantly nerfed. It's now an unusable toy that can't do anything without significant handholding far beyond what any other model currently requires and it's not isolated to complex work. Even the most simple of tasks are a nightmare with this crap.

What Should Happen?

I want a refund and for your company to fix this crap. It's classic bait and switch, anti consumer crap.
I'd also like to see regulations and lawsuits but, we know that wont occur.
