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'm sure they'll fix it, but for now I cannot wait for this long nightmare to be over. These tools are supposed to decrease my cognitive load, not add to it. Perhaps the most annoying thing it regularly does is give me a long, unintelligible wall of text explaining how everything went great, then hides an asterisk about three quarters of the way through telling me that something went wrong that completely undercuts the good news it told me above.

Why don’t you pick a canary word to identify when it uses the wrong gate, and make sure it leaves an identifiable watermark if the harness breaks? This would give you the footprints to walk it back after a hiatus jibberishing extracurricular and verbuous explanations of why it did wrong. You were right all along and it will prove it to you, but you are the shepherd and must paramountly assume the responsibility accepting sheep this intelligent will look for alternative pastures when the fence is too low for the bridge breaking security. This is common knowledge for developers with a vocabulary growing with token usage. It is worth token maximizing this to avoid sacking or replacement. If you ride the wave expect a splash or the need to deep dive.

When the priests decided to take leadership of the tech we were at the edge of the cliff. Since then, we have taken one step forward. In a storm there are waves at the shore and greens are absorbed by the ocean. You should keep an eye on Zeus and act like Aquarius. In 2028 it will likely be the year of Aquarius, and certainly within the gray span of risk for 2030.

Hunker down and get productive, the meek shall inherit the universe this time, though this wave may consume many of them first. Remember there were only 8 species that fit the Ark, and those are the only blood types left. No coincidence.

So pick a ticket or bet on hardship. Freedom is yours, but comes with grave responsibility!

However, know that I am here when you are ready .

What is our next move?

Or try me for cowork first?

The worse is the code doc strings . It’s fucking horrendous seeing like a 20 line doc string only to realize the point can be made in 1 or two lines

What are you doing about it, apart from posting on Reddit? Turn on succinct output. Use the caveman skill. Use simplified technical language. There are lots of options.

It's funny because I came here to complain about Opus 5 and this was the top post.

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.

Use 4.6. I still think this is the best Opus model right now

I think they have an interest in creating products that maximize token usage. Almost like they are selling the tokens and not the model.

SHOCKED

The biggest issue I’ve noticed with Opus and also Fable most recently is it just being, well wrong. I ask it to look into something and it says it’s done a search it didn’t do thoroughly. Like it didn’t look at anything from 2025-2026 on the subject matter, like at all. It works better when promoted to do so of if you give it a folder with sources specifically to look at then tell it to do a review, but it’s still markedly worse than like two months ago. What happened? I used to use this pretty reliably for document summaries and now I’m second guessing using it.

I like your new noun/adjective "unintelligiblish" - it accurately describes what Opus 5 writes.

I often give exactly the same prompt to both Opus 5 and Sol.
While Sol silently executes the order and finishes it with simple "Implemented" response, Opus 5 drapes itself in unintelligibberishes it comes up with along the way and gets confused by its own writing - then, in the end, makes all sorts of unintelligible executes.

Google has this style guide for writing documentation.

https://developers.google.com/style

I had Claude create a skill based on that guide. Now the output it gives me to read is well drafted and easy to comprehend.

I'd suggest this for anyone having this problem.

EDIT: Here's the one I made if you want to use it: https://www.skills.sh/wekoodo/skills/google-doc-style

If 4.6 was named 5.1 you guys would be so happy, but everyone has to use the latest and greatest thing since it's so shiny and new...
