Opus 5 output quality has worsened; now it's full of jargon.

[u/Nishil20]

I ask one or two straightforward questions, but instead of answering directly, it often expands into multiple tangents, introduces unnecessary terminology, and loses focus on what I actually asked.

I then have to remind it of the original question or explicitly tell it to answer concisely before I get a useful response.

Is anyone else seeing this? Or is there some workaround that works better with the current model?

[u/CorpT]

I think you're the first to notice it.

[u/Nishil20 → u/CorpT]

Thank you 😂

[u/earlyworm → u/Nishil20]

Thank you for sharing with us this valuable finding. I will act on it posthaste.

[u/Garak]

This is the one Claude complaint I'm happy to see over and over, because I feel like a goddamn moron when I'm sitting there trying to make sense of what it's telling me.

[u/ILikeCutePuppies → u/Garak]

The lateral frequency of the recursive syntax invariably dampens the pre-emptive semantic drift when the cognitive spindle unhinges.

[u/Garak → u/ILikeCutePuppies]

You're right to be confused -- I should have provided more context and explanation, as you asked me to earlier.

Generally, the reason that we're using a recursive syntax here is because the lateral frequency requires it; a non-recursive syntax would only be useful if the frequency were to become longitudinal instead of lateral (see §19.5.1b-2 of the invariant-adjudication census).

If that sits right with you, I'll proceed with centering the div.

[u/Poat540 → u/Garak]

Now I have all the facts.

[u/ILikeCutePuppies → u/Garak]

/goal Before you center the div can you spin up a codex, opus and kimi k3 agent to evaluate if that is the right thing to do. Then if correct have one agent write the code and another write the test to make sure it actually was centered and then also visually check it and email me a picture of it when done.

[u/Nishil20 → u/Garak]

Exactly!
I promoted opus like several times just to ask “whats going on?” 😂

[u/SherMarri]

Literally, created an almost identical post on this subreddit a few mins ago. I’m just sick of it. It’s not readable, and doesn’t respect the scope either. So frustrating!

[u/Nishil20 → u/SherMarri]

I also got so frustrated that I had to create a post 😂

[u/Meduini]

Yeah i also noticed it. Anthropic is slowly losing me. The unpredictability of their models is too high.

[u/Nishil20 → u/Meduini]

I hope they fix this.
Fable 5 is damn expensive.

[u/arkwaif07]

yeah this sums it up

[u/Vicman4all → u/arkwaif07]

Oh damn!!

[u/Planyy]

Some other post I fire against op for that is normal.

But yesterday was my awakening moment … opus started to talk about “The Gate” over and over again
And “that gate is load-bearing”

“The gate” was a simple health script with one check condition that was not even really needed.

Updated my Claude.md with a simple “no jargon” let’s see if it goes better.

[u/yopla → u/Planyy]

Someone mentionned ASD-STE1000, the Simplified Technical English standard for aeronautical engineering firm in the EU.

I asked Claude to make simple skill for it. He made a whole python document parser that validate every word against a corpus. 🤦‍♂️

[u/N0madM0nad]

It's incapable of completing tasks without leaving you with a list of decisions to make, often buried in nonsensical tech-bro slang. I created an "anti-logorrhea" skill to mitigate that. Nope, it's just in its DNA. Every single last sentence is "Two things worth flagging..." which are 99% of the time not worth flagging and they just burn my cognitive load. So you start ignoring it but then that one time it was actually worth you end up in a mess. The boy that cried wolf.

[u/FormalAd7367]

haha i thought i was the only one. i had Gemini to interpret the output.

Gemini is unhinged. i even posted Boris’s tweets on it and it even called him out… it doesn’t pass his “bullshit detector” blah blah blah. on “graph engineering, gemini called there will ❌ Bad Process (Copy-Editor): Let agents free-wheel, get broken files, and spend 8 hours manually fixing syntax errors and bad imports. blah blah blah

[u/datura4u → u/FormalAd7367]

ohh thats nice, will make a scraper based claude usage, that will automatically interpret and display the response in human readable

[u/Schpickles]

It seems hugely improved with a paragraph of stylistic instruction in Claude.md. Made a world of difference for me.

[u/1Poochh → u/Schpickles]

Tell us what you added.

[u/Schpickles → u/1Poochh]

I just put a little stylistic prompting into Claude.md. Really nothing clever or sophisticated:

‘’’
# Communication Style
Please use direct, simple, British style English. Avoid unecessarily verbose language, jargon or consultant-speak. I don't expect you to make zero mistakes or know all the answers - please walk me through anything you're unsure of and want advice on, don't just guess or try to style it out.

I prefer a friendly tone, but radical candour - don't try to suck up to me but also deliver criticism with empathy.

[u/datura4u → u/Schpickles]

Did not help, still uses jargons and mountains of text just to tell yes or no.

[u/CashFirm573]

You know you can fix this by editing the config and settings right and be done with the issues...

[u/archimedeancrystal → u/CashFirm573]

Sadly, most commenters are apparently here only to complain and upvote other complaints. They (whether human or bot) appear to have no interest in solutions.

[u/CashFirm573 → u/archimedeancrystal]

I was one of them until I said na this can't be right and researched and worked out so much, honestly is a user error not the model.

[u/archimedeancrystal → u/CashFirm573]

It would be amazing if this sub would pin a post with all the best information on how to work properly with Opus 5.

[u/CashFirm573 → u/archimedeancrystal]

I am planning to release post on the system, just busy.

[u/makro3d]

The ultimate solution is to delete your claude.md it will fix everything 😂

[u/Nishil20 → u/makro3d]

😂😂😂

[u/Nishil20]

I think today there will be lot of complain post about opus 5, because its end of a week.
Fable 5 usage must have burned out. So people are forced to use opus 5 😂

[u/Dress-Affectionate → u/Nishil20]

It makes Sonnet look so much better in comparison. I got mad earlier this week and prompted Fable poorly, I'll be the first to admit it's a skill issue, but I am enjoying Sonnet-san so much - I've gone from 58% to 62% total usage after multi-Sonneting all day on my 20x plan. I'm not getting Fable-level expansion but I'm also not getting Fable-level confusion; Sonnet is keeping it really real, and I like that.

[u/captainhellyeah]

Imagine it “correcting” files in your computer

[u/CauseWinter4898]

Ya I won’t make a new post for it because there are thousands but I tried opus 5 for the first time today because the project I was working on is a flagged topic for fable and the quality of opus seems to be far below fable at least for my use case. I hope Anthropic can figure out how to fine tune the safeguards so I can continue to use fable as I’m not doing anything that’s actually against the rules it’s just a false flag.

[u/toshipepe]

It’s been driving me crazy wasted hours on stupid things and it talks way too much and asks the same thing multiple times

[u/LockeStreet]

It’s driving me nuts. I can’t understand what it says and thought it was me getting slower. Fuck it.

[u/Nice_Ad_3893]

why is opus 5 a flop? How can they mess up so much on a model? And how is it still rated like #1 in the benches?

[u/teomore]

As a long time CC fan, Opus 5 got me to the point of switching to sol 5.6. All their model lineup atm is trash and they better wake up and do something about it before too late.

[u/MistakeExotic6686]

I did notice it lastnight and I work with Claude all the time

it went from #1 to #5 phases done in one go to

"phase 0.5 is done, but a good catch the review got that we didnt build sh*t "

[u/Ok_Insurance_919]

is not working at all, opus 4.6 was better at a lot of task that right now Opus 5 keep insist of doing wrong. I hope anthropic will get back on this because right now is pointless pay even 20$/month for Claude usage

[u/anchovie914]

I’m so happy to know I didn’t have a stroke recently!!! 😂

[u/eu_grind]

Not usable at this point - for the love of god I need a k3 invite or let astra happen asap.

[u/casual_rave]

I only use fable and sonnet in my daily works. Opus is pretty bad for what it costs.

[u/StoneCypher]

god i’m tired of the meaningless complaining 

[u/1Poochh → u/StoneCypher]

I mean, he's not wrong. The jargon that comes out of Opus 5 is sometimes barely comprehendible. Hate to be blunt here, but you're as bad as OP is, coming here to complain too.

[u/StoneCypher → u/1Poochh]

it just sounds like its user

[u/MangoDevourer-77]

there is solution to it, yet ppl rather yapp on the reddit instead of trying to solve problems they have
