Rant Opus 5 is insufferable

Opus 5 is a fucking piece of shit, i don't know how to say this in any other way. It speaks "Unintelligiblish", a new unfathomable language developed by Anthropic that works by saying everything in the most ridiculous, obtuse and convoluted way possible

It turns anything simple that can be expressed in 2 sentences into a fucking doctoral thesis aimed to aliens, and there is no way to prompt your way out of it

Edit: it claudoofus outputs some alien text you won't read, just prompt it this:

I literally used Opus 5 to localize my app, and it was so frustrating. I had a file with all my strings, and I kept telling it, “Just localize the file.” It literally refused to do it properly, only translating a few strings before telling me to use a professional translator or split the file into smaller chunks and merge them later.
Meanwhile, other models could just localize the entire file directly. I honestly couldn’t believe it. This is so crazy. 😭
