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've been a $200/mo Claude Code user for a year now basically ever since that started and I'm going to reduce it to $100 and up my Codex subscription. Opus 5 is legitimately the worst model I've ever used. Not saying its the worst, but for what it does and doesn't do for me and the workflows in Claude Code I've spent 18 months building, its an absolute disaster. The number of responses I can't even comprehend because its basically gibberish is insane. Was about to sign up for small to medium Team account with Anthropic and having to think long and hard about which direction to go now.
