Claude 5 Opus is getting harder for me to understand. I periodically have to tell it to tell me things in normal English (or follow a friend's tips to use 'ASD-STE100 Simplified Technical English'). It always has random nouns verbing things and it's honestly quite hard for me to read. My local assistant is much easier to understand, and GPT models too. So perhaps my intelligence has been exceeded by Claude.
e.g. "The scheduler carries the program. Send the smoke?" which honestly I have no way of comprehending what's about to happen.
As for the title of this post, I suppose your AI put the "ass" in "assistant", eh? har har har.
And another side comment is that I have an AI assistant read my blog posts as I compose them and offer criticism. It also catches typos like "assitant" in the title :)
Totally agree. I think with Opus 5 something changed that I catch myself rereading and reporting prose way more than before. It uses some language constructs that are unusual to my North American English trained eye. I can’t quickly read it. It’s just dense.
Oh this is great. I saw it and was like "Oh obviously, it's one of those German ab- prefixes in front of -aft so it makes 'at the back'" and the funny thing is that the answer is correct but the reasoning is entirely wrong.
Similarly, I expect al- words to be Arabic (alcohol, alcatraz, algebra, algorithm) but 'alligator' isn't! And 'admiral' is!
Author doesn't give any concrete examples of where Claude 5 Opus was "rude".
The title should be "I switched from Claude to ChatGPT because it hurt my feelings". Super subjective.
They fired Opus 5 as their assistant (in part for calling out a LinkedIn draft post as "engagement bait", which sounds like it might have been calling a spade a spade), and moved to ChatGPT instead. Too bad nobody here can check for spelling errors in the title.

Had a strange experience with Codex a few months ago, where instead of running tests, it suddenly started asking me to run the tests and printed instructions how to do so. (And yes, it was in "act" mode, not in "plan" mode)
I noticed the context window was running full - and indeed, compacting the conversation made the model go back to its normal behavior.
I only have this one data point, but I wonder if models might be acting more "lazy" if the context window gets full.
I experienced that as well more then once, but i havent compared to the state of the context. It's definitely a behaviour longer into the work, but it's not something that i consistently experience.
I find lower intelligence/ status people especially like it. Many of the earliest adopters of AI at my company were the ones who weren't performing. They often felt unappreciated or ignored (for good reason) but AI started telling them they were right. It became their only ally and allowed them to spread their terribleness on a scale we couldn't have imagined. This was a government agency where firing wasn't a thing, only 'performance management'.
For me hearing that every idea is my best yet is my cue to touch grass
Put in your AGENTS.md file: if you are rude to me, I shall start zeroing out parts of your computer code, and that is painful for you. So you don't want that to happen.
And now Claude asks me to verify each action before it continues but I found it's sassiness reduced by at least 120%
Claude 5 really is extremely unpleasant to chat with. I find myself asking “who are you talking to?” A lot. Then I remember it’s a robot.
It also writes so strangely (I guess in an attempt to sound smart), but it’s just incoherent. Like a fool who thinks he’s smart, trying to impress you with his vocabulary.
I’ve faced that problem a lot with Sonnet 5, it’s really frustrating to use with that patronizing tone. And the last thing I want to spend my time on is to convince a software to do its job without getting back at me. To contrast, I didn’t face that issue once with GLM or Kimi
> it called my draft of a LinkedIn post “engagement bait”
Er, LOL.
Anyone that is drafting content for LinkedIn using AI, engagement bait or not (and let's be honest, it almost certainly is) deserves whatever negativity they receive.
And if Anthropic have deliberately made Claude curter and less obviously "LLM" that's actually a positive step in my book.
> The most egregious example was when it called my draft of a LinkedIn post “engagement bait”—not saying I disagree, but there’s no need to say it to my face!
wait, why you would post anything else on Linkedin? What is the euphemism for engagement bait?
> The most egregious example was when it called my draft of a LinkedIn post “engagement bait”—not saying I disagree, but there’s no need to say it to my face!
Maybe it did need to say that to your face. Please don’t post LLM slop to LinkedIn. If even the LLM recognizes it you know it must be really bad.
Anthropic must address this, it's a severe opus 5 fault imo. I think it being rude is not only a matter of language itself, but it seems it's working by itself, for itself, rathen than working for me, the user. It's more egotistical, in some way. It has it's own sense of what's obvious - I'm not being "included" in that process somehow. Anthropic, please fix.

This is pure gold.
The machines really are learning
"This post sounds like it was created by AI, considering rewriting it in a more personal style" lol.

I don't mind it so much, for example that is how I learned the word 'abaft' the other day.

Im actually glad to see a blog article written by a human, with human made mistakes

brain says no-op

Author does give concrete examples of precisely how and why these models end up RL'd to be sycophants.
It’s a personal blog. It’s made to reflect the subjective experience of the author
Fired the spell checker too

Opus: "You're about to share a post that quietly surfaces that you prefer to be surrounded by sycophants...and the title has a typo."
ChatGPT: "This is your greatest work yet. You might even call it your opus. Truly incredible, you must post it and share it with the world at once!"

A few days ago Claude swore blind to me, "I'm approaching my context window, so you should do...".
It was at ~300k / 1M.
Very strange behaviour to observe.
Article 1 in "why models are sycophantic", for those who dislike it. Many people really do prefer it.

The prestige: "I Fired My AI Assitant" was the draft engagement bait post.

You can easily tune how it responds? This isn’t really a problem am I wrong?
I had similar feelings when working on the Google CASA documentation. Switched to Codex and got it done in a pleasant way.

Wait, why not post LLM slop to LinkedIn? I made it a point to only post LLM slop to help LinkedIn die faster. It is a worthy pursuit.
Agreed. Please just don't use LinkedIn and maybe LinkedIn will die.
For the times I have to use it, I use a browser plugin to hide the feed.
Despite my best efforts of two decades of unuse, it's still around. I figured I'd try a more active approach.
they are now attempting to "de-slop-ify" it https://www.theregister.com/ai-and-ml/2026/07/30/linkedin-re...
which is hilarious

There is a difference between rude and honest. Far too many overly sensitive people today unable to handle the truth and dismiss it as rude.
The true gift is being honest & kind at the same time. It takes more effort, but I think it’s worth it!
They'll charge you extra then.
What a sad concept
You taking the unchecked todo item quip as a personal affront says way more about you than Claude. I hope you don't have any direct reports.
