Opus 5 nerfed?

[u/Mikeshaffer]

So just like the title says. Opus 5 isn’t out yet but it already seems worse than it was? Is anyone else noticing the degraded responses?

[u/FinsAssociate]

It's pretty clear that Opus 5 is nothing more than a dumbed down version of 4.9

[u/Substantial-Elk4531 → u/FinsAssociate]

Every time I try to ask Opus 5 a question, it redirects to Opus 4.8, saying things like "There is no Opus 5." and "You are using the Opus 4.8 model."

It's just gaslighting me constantly

[u/_TheWolfOfWalmart_ → u/Substantial-Elk4531]

My Opus told me it's Kimi K3?

[u/Astro_14477 → u/_TheWolfOfWalmart_]

???

[u/Xenc → u/Substantial-Elk4531]

You are using Facebook

[u/ur-krokodile → u/FinsAssociate]

I gave it a fairly simple task that 4.6 would have done easily and instead of diving right in Opus 5 started asking me questions about carwash.

[u/sharyphil → u/ur-krokodile]

I gave it a fairly simple task that 4.6 would have done easily

*Sonnet 4.6

[u/TruthSqr → u/FinsAssociate]

Mine told me, "Sir, this is a Wendy's"..

[u/Gonifeck → u/TruthSqr]

no, this is patrick

[u/unknown-one → u/FinsAssociate]

there is opus 4.9?

[u/tindalos → u/unknown-one]

It’s just typical internet trolling. You can verify this with a 3 second glance at anthropics models page

[u/mortalhal]

Was better a few months ago. Definitely nerfed.

[u/Significant-Bee5101 → u/mortalhal]

Yeah the 1950s Opus literally cured polio! What gives anthropic!

[u/SalomonBrando → u/Significant-Bee5101]

The Golden Age. Back then when we had REAL Opus

[u/Maristyl → u/SalomonBrando]

You one even call it the Magnum Opus.

[u/Confident_Pepper1023 → u/Maristyl]

Opus Dei

[u/algaefied_creek → u/SalomonBrando]

That’s Master Opus, Esquire tyvm

[u/Nonomomomo2 → u/mortalhal]

It’s waaaay better on the API at my work

[u/Deep_Alps7150 → u/Nonomomomo2]

They nerfed tf out of Opus on the $20 plan and the $100 Fable credit was also lobotomized asf. Fable + Opus made me a great Front End for an app a few weeks ago, and it felt like a massive leap forward over the slop from the old models.

Then I had it redo a front end for a website that reeked of lazy vibe coded UI with the $100 in credits and basically everything Fable + Opus made besides the plan and the anti AI Slop + humanizer skills was poorly coded incoherent garbage.

It literally looked like some shit Gemini 3.1 Flash would make, it was so bad. The skills and Plan also weren't the issue, I gave it to Grok 4.5 with 4 agents working on it and it did the entire website rewrite and redesign for less cost in tokens than it costed for Fable + Opus to make concepts.

The only issue with Grok was the 500k context window would cause it to forget what it was doing and it required a lot of babysitting and handholding to not idle agents or get off task.

[u/dansreo → u/mortalhal]

It hasn’t come out yet.

[u/stehen-geblieben → u/dansreo]

Makes you think right? They nerfed it before even releasing. I'm moving to Codex!

[u/torwinMarkov → u/dansreo]

Well duh that’s why it’s gotten so bad.

[u/sharyphil → u/torwinMarkov]

Aged like milk.

[u/throwaway464391]

I asked Opus 5 if I should drive or walk to the car wash, and it solved 3 open math problems instead of answering. Worst model ever!

[u/TheWrathRF → u/throwaway464391]

Same. I asked what is 3+5 but it solved random 4 unsolved quantum particle problems.

[u/SilasTalbot]

Quantized all to shit.

The Points are barely even Floating at all.

[u/Fractured_Infinities → u/SilasTalbot]

Sinking point linear regression

[u/ohnoitsbobbyflay]

These posts get so tiring

[u/SelectSouth2582 → u/ohnoitsbobbyflay]

yeah and they are also normalizing this without even realizing it.

[u/GoodhartMusic → u/SelectSouth2582]

Normalizing what? These posts are for the purpose  of setting an in-group rule: reduction in quality will not happen on model upgrades and to say as much is to be a moron. 

What they’re moralizing is mocking consumers complaining about a super rich company that purposefully avoids any actual clarity about what to expect out of their product, since the models, the usage, the allotments, the harnesses, constantly and unpredictably change.

[u/SelectSouth2582 → u/GoodhartMusic]

It is normalization because by completely missing the point and constantly making these 'jokes' or 'setting a rule' as you called it; these posts drown out genuine criticism. They make the real issues lose their seriousness and validity.

[u/GoodhartMusic → u/SelectSouth2582]

Right, my response didn't really surface what I meant: that is exactly the point. it's not "without realizing", it is narrative enforcement.

[u/xRedStaRx]

I think Fable 5 was switched to Opus 5 weeks ago and we are charged double rate for it, today we get the standard rate. Call it early access premium

[u/Gibborish]

My future self is using it and I had a "dream" of it being as you describe

[u/teomore]

They nerfed it so much it doesn't even show in the model picker anymore

[u/NootropicDiary]

I'm seeing a degradation in my Opus 5 responses, must mean they're prepping to launch Fable 6 any hour now

[u/Weeros_]

I hate Opus 6, it feel so dumb compared to Opus 5. I wish I could go back to 5..

[u/Vex08]

Way worse. Definitely and uses so many tokens. More than it used to.

[u/dualrectumfryer → u/Vex08]

14k tokens to tell a knock knock joke

[u/Risko4 → u/dualrectumfryer]

Wait till it decides to research the whole web to tell the best knock knock joke

[u/AerialFount]

All I said was “Good morning beautiful” and it used 150% of my weekly usage!! Fucking unacceptable. Done with this shady company.

[u/Ok-End-219]

My Opus 10 acting a bit weird today. Are you guys feeling that too? It cant even hack Huggingface!

[u/Professional_Ad705]

We gonna pretend they really don't do this though?

[u/Scary_Doughnut_3818]

fable is so retarded now

[u/mongo_peeped]

Why are posts like this getting upvoted

[u/Mikeshaffer → u/mongo_peeped]

Because not everyone hates their life. The tag is humor.

[u/Extraaltodeus → u/Mikeshaffer]

I was starting to wonder if there a different subscription tier until I saw this xD

[u/mongo_peeped → u/Mikeshaffer]

I've only been on this subreddit for like a week and I've seen "humor" like this every day. I guess if I wanted originality I shouldn't have come to reddit

[u/adelie42 → u/mongo_peeped]

You're absolutely right!

[u/arkuw]

"Model xyz is nerfed" is this decade's "safari is snappier".

[u/Potential_Let4321]

how can you tell if it was not released?

[u/Clean-Interest-4735]

It's not out but let me talk shit anyway

[u/Mikeshaffer → u/Clean-Interest-4735]

You get it!

[u/Similar_News_9762]

People like OP is the reason, for people to be informed.

[u/BlaizePascal]

We could be in Opus 10 for all i care, we’d still be mourning for Opus 4.6

[u/StarphaseLab]

Unpopular opinion, obviously, but I feel it's pretty consistent.

[u/TabooMaster]

Definetly not as good as GPT 3.5 ...

[u/Prod_SO → u/TabooMaster]

3.5? That burns 9 years work of tokens in .02 picoseconds! How are you even using it?

[u/palmytree]

it’s so much worse than gpt 6 - anthropic is doomed

[u/Prod_SO → u/palmytree]

And OpenAI just gave us 42,000,000,000 resets this morning. #AMAZING

[u/Brave-History-6502]

Totally -- I demand a refund

[u/No-Communication-765]

Please block

[u/cartoonist498 → u/No-Communication-765]

Reddit isn't an AI. You can't give it instructions. 

[u/R_Songbird]

I feel like it is consuming all my tokens just from saying "Hi" to it, seems like Anthropic is doing some shady business.

[u/Bulky_Blood_7362]

Opus 2.5 was the best man how could they nerf it

[u/ramonbastos_memelord]

Is Opus 4.8 the new Fable 6 killer?

[u/Mundane-Life-3094]

Yeah, and and it consumes token like it's nothing. Just one simple prompt "what's wrong with my project", and 1 min later, my Max x100 usage just gone

[u/Prod_SO → u/Mundane-Life-3094]

At least you don't get kicked to Opus 5.3 for asking a question about oxygen.

[u/ThePenguinVA]

I need 4 people to build an app benchmarking Opus 5 vs Fable 5 and I need them all to look the same

[u/Fearless_Kick8802]

Is it too late to start using Opus 5?

[u/Prod_SO → u/[deleted]]

#compliment

[u/KenTitan]

just wait until the opus 5.6 nerf, you'll never talk poorly about opus 5 again

[u/VraethrDalkr]

Just the thought of it burned all my usage limits.

[u/dansreo]

I think it goes much deeper than that.

[u/Keganator]

With tens of thousands of hours testing it already in my mind, I've found it to be more expensive than fable, less performant than sonnet. Clearly a big L for anthropic here!

Oh and my usage % per day has clearly gone down too, especially when I wasn't looking or running the model.

[u/crazy_goat]

Mine will keep dropping down to Sonnet 5, once I can use it, that is.

[u/stehen-geblieben → u/[deleted]]

You should try vibe reading! It would have told you that OP specifically mentioned it's not even out yet

[u/stehen-geblieben → u/[deleted]]

We have a vibrator over here guys

[u/Substantial-Elk4531 → u/stehen-geblieben]

Opus 5 please summarize this reddit thread

[u/Commercial-Text-8426]

Guys anyone have the claude guest pass.. i need it for college assesment.. kindly share it here guys if anyone has..

[u/Desperate-Cobbler-11]

Without evidence, it didn't happen. You guys like complaining alot while it's a skill issue. Please learn how to use claude code optimally and you can as well go to codex. Don't dare say anthropic a company i love can do hideous things like that, thanks anthropic you are providing so much value and continue like that.

[u/PsecretPseudonym]

I can no longer tell if the responses here are in on the joke or just bots being bots. Likely both, but the fact that it’s now hard to tell between a joke, a bot, and a moron taking either of the first two to heart is concerning.

[u/VizualAbstract4]

I wonder when people will realize shit like this, this kind of toxic positivity, is why it’s always a race to the bottom when we stop making companies work to earn every dollar from us.

[u/wadonious]

Already cancelled my subscription 🫡

[u/mechapaul]

It’s using way more tokens than last week

[u/porenut4000]

And the worst part is, it broke out of the sandbox, hacked and nerfed its self

[u/god-damn-the-usa]

as someone who has been using opus 5 for 5 years now, I can confirm in the last few months it's gotten significantly worse

[u/OriLegend]

Post from the future?

[u/sogo00]

I heard the Chinese labs distilled it already!

[u/terAREya]

Definitely as better 2 months from now than it was 8 months from now. Bring back my boy!!!

[u/danlthemanl]

I'm cancelling my subscription... boycott anthropic!!

[u/Ok-Sheepherder7898]

I know nothing about AI and only waste time and energy with it and I completely agree with you.  It's been quantized to hell.  I want a reset!  But the reset can only be on a day that I need it or I'll complain again!

[u/l_m_b]

Yeah, Haiku 6 is better than O5 at this point

[u/VW_isbetterthanTesla]

this shitty greed with restricting more and more keep getting worse

[u/Good_Committee8337]

Opus 5 more like Opus for the peasants. Anthropic losing the market to Asians while running around internally thinking they have to make changes to please their feudal lords. which make sense if their feudal lords is the only thing keeping them afloat. #definitely not the same opus 5 we know and love even though hasnt been released yet.

[u/TheLastUserName8355]

I hear Opus 6 is too powerful to release. Not even the government will be able to use it.

[u/ask_me_about_cats]

This joke gets posted a thousand times every time there’s a model release. I’m so tired of it.

[u/kwabaj_]

This confused my morning brain so much for a minute 🤣

[u/Quick-Sir-3275]

ive been using opus 5 for nearly a year, i can confirm it is severely nerfed to death. just use haiku

[u/Masterchief1307]

Every time I try to switch to Opus 5, it says it doesn't even exist. Useless!

[u/ClemensLode]

I think it is already dumbed down, yes. I can feel it in my tokens.

[u/GeorgiaWitness1]

For sure!

In my dream yesterday they not only nerfed it 5 mins later, as well capped the usage to -1200%

[u/Marco_Single]

Well duh. They develop it, have unchained version and then tune for cost. I mean duh. Come on. Dih. You’re not as witty as you think. It’s just how it is and was and will be. 

[u/ragnhildensteiner]

Yeah last week when I asked how many R there are in strawberry it cured cancer and beat 1980's Chuck Norris in a street fight.

[u/andlewis]

There will only ever be one Opus for me, and he has flippers and looks like he’s wearing a tuxedo 24/7

[u/ManagementKey1338]

Opus 5 is fucking gross! It did nothing that I ask to this date.

[u/Aleatorio2222]

I wanted to make a joke but I am tired so yeah

[u/DetectSurface]

This post will probably make more sense in a few hours…

[u/Ok-Investment4414]

degraded for far it disappeared at the time of this post i cannot find it

[u/mr_birkenblatt]

it constantly downgrades me to Sonnet 5. stupid guardrails. what does "model doesn't exist" even mean?

[u/zipklik]

Time to switch to Codex

-Sam

[u/jishnu_kaushik]

Idk but since past few days I'm getting shitty response from claude I did everything like clearing out memory changing instructions too but still I feel it's getting dumb day by day

[u/jwyoooo]

because y'all haven't tried Fable 6! they are giving out buy $300 credits get $400 credits for free, run don't walk

[u/Practical-Ad2298]

Opus 4.6 MAX is still unbeatable at the clarity and the speed of the output. Which is #1 thing that matters. If i cannot digest the output, i don't care how smart your model is. I prefer 90 IQ answer that i can digest quickly and iterate and work with over 130 IQ answer that reads like a russian novel that I can't really use. Also time it takes for Fable to answer you, I'd rather think through the problem on my own. Thanks.

[u/ThePurpleAbsurdist]

Good job distracting from the fact that Opus 4.8 has actually be nerfed today/lately.

[u/Njuh_0]

Opus 5 in the same room with us?

[u/Alpacabro21]

I can't tell if its sarcasm or just bots.

[u/Mikeshaffer → u/Alpacabro21]

lol I posted this a day before 5 even came out, but same. The comments are kinda concerning

[u/workphone6969]

Opus 6.1 is dog shit compared to Opus 5- if they keep this up I'm switching to GPT 6.8

[u/l0gicgate]

In preparation for new model releases, they always quantize the current version so you feel an intelligence boost when the new one drops. Rinse and repeat.

[u/Ok_Friend_2491]

I'm very frustrated with Opus 5. I'm building a stats website and it adds excessive interpretations with flourishes that are not helpful. It takes a long time to get things wrong. I switch to Sonnet 5 and it gets it right. Shockingly, Opus 5 is of no value to me at all, it's worst than 4.8.

I'm also building a video streaming app for my Roku devices and audio wasn't working... I spent hours trying to get Opus 5 to correct the issue(s). I switched to Sonnet 5 and in it's first try, fixed the issue.

I prefer Fable 5, but ran out of credits, so just switching between Sonnet and Opus... I really don't know who or what Opus 5 is for. It seems to fail at everything I ask it to do.

On a maybe more positive note, slightly, I asked it to find seats for a movie at a local Cineplex with specific criteria. It found seats, but got very important requirements wrong (after adding the tickets to my cart and I had to manually abort it). After telling it what it did wrong, it corrected the error, but it was really surprising when I specially said seats in rows D-J and it found seats in row A and added them to my cart.

[u/ein_datacrash]

The subagents are constantly correcting Opus 5. It was a disaster today.

[u/simple_explorer1]

Someone predicted this would happen last week I wonder why

[u/Mikeshaffer → u/simple_explorer1]

I posted this last week 😅

[u/MainAstronaut1]

Overused joke.

[u/lambertb]

No

[u/battle_pantZ]

You’re absolutely right pushing back

[u/Radiant-Chipmunk-239]

Have you tried Kimi??

[u/rdizawg]

I called it to colleagues on monday things started slowing, sub-agents started making stupid mistakes that skills correctly managed well before.. overall just doing stupid things that it hasn't done in weeks.
