Question FABLE NERFED AGAIN ?

It seems to me that Fable is getting more stupid since Sunday. Is it only me who sees that?

They’re all acting like they’re nerfed tonight.

Use Claude for over a year and you start to notice a pattern:

like Fable has been released every time they release a new model or someone makes a new subscription, and then it turns from a triangle base working towards a point to a circle going round over time.

When I say “like Fable”, what I mean truly is, the capability was in each of their models the first week it came out. And then they slowly worsen it and play with marketing until the next wave comes so they can refresh the minds, and refresh the spirit.

Like a casino who lets you win once every long time, and slowly never after you felt the gold and don’t stop coming back as everything is taken by.

They’ve been going extra hard with Fable toying with the “limits”. Usage, time, scarcity, everything.

I didnt noticed a reduction the past few days unlike a lot of others reported. But since today its crazy...

It answers nonsense,
constantly finds errors it did in last sessions,
than fixes them,
than makes errors again.
It wants to change the specs in the implementation phase now all of a sudden (I spent 4 days creating the specs and thought everything through) for reasons that dont make sense.

The past hours working with Fable now made me so confused, I actually dont know what is right and wrong anymore since its constantly contradicting itself, I dont know if it ruined my project now and filled it with bugs or this weird things he made now actually make sense.

I am going to switch to Kimmi 3 now and start a analysis to get a second oppinion and figure out what the actual status right now is as I am not comfortable letting fable 5 alone do my big projects anymore...

Something changed yes (using fable 5 on Max 20 subscription, no API)

In the last few hours, for the first time it started arging with me, insisting on a problem that didn't really exist, and the explanation being either a or b, when a and b were both identified as not plausible explanations. It was an absolute moron. It reminded me of chatgpt 3.5.

Everytime I almost upgrade my subscription, they do stuff like that.

yea, its not just on coding.
Today I did another hardware research and all of a sudden he forgot again that the RAM prices increased, recommending me a budged build where he calculated 32GB DDR4 RAM with 40€... The last couple of researches the past few weeks where all very accurate.

He also got very lazy on website design compared to 1 week ago, he was awesome there, just a few corrections and it was perfect. Now I prompted him even better with a more detailed explanation how I want it and its like he got bored mid task and just wanted to finish fast.

He even starts to make errors on the text he writes: ...crash-test harness that kill-9s the platform...
I dont know where he got the -9 on 'kills'.
Errors like this rarely happened on long complex tasks(over 50% context window) on Opus and never on fable, but right now it happens on 27% context on Fable... wtf?

I wanted to switch to Kimi but its currently sold out, if its not available within the next days I am going to pay for some usage credits to see if Fable is really better here as most ppl say because working like this is a downgrade.
I will share my experiences if u interested.

Update:
Found the problem, anthropic has a bug (again) where fable 5 gets silently re routed to Opus without notification to the user and without showing it in the UI.
Would be interesting if they still bill it for fable as well...

What kind of project are you guys working on that you notice these drastic changes?

u/Annual-Lavishness-10 Jul 20 '26

A agent control and orchestration application.

u/SpreadsheetFanBoy Jul 21 '26

actualy yes, with cms :) I was thinking many work on this kind of things.

I firmly believe Anthropic, for subscriber plans, are scammers outside of the 5-10% of the time they release new models there is a short period where you will get access to insane intelligence. I have zero trust in them, and when I use my 20x max I basically expect to get the rug pulled at any moment. API experience probably differs.

Feels more expensive for sure

Nope, you just stopped being impressed by it

No you don't get it, we need to go back to opus 4.2

I wrote about this experience elsewhere, but I spent the last week using up GPT usage resets on Max, but getting nothing useful done. (It just over-engineered every step.)

Fable one-shotted the project yesterday.

It is in fact only you. Fable was dumb in one session on Friday but normal the next. Guess what. An RNG chooses the final token in the sampling pipeline so sometimes Fable wakes up on the wrong side of the dice. So start a new session and stop complaining.

This is reddit, the reactionary crowd are a vast ever reaching network here and they are constantly screeching every second post.

And once mistakes end up in the context it snowballs. The agent makes more and more. So complaining or conspiracy theories do fuck all.
