SemiAnalysis power users migrate development workflows from Anthropic to OpenAI Codex following persistent model refusals
The migration triggered a measurable spike in Codex usage.
Positive users are switching to OpenAI Codex from Anthropic models because of fewer refusals and restrictions, while negative users complain about OpenAI's SMS verification hassles.

@thsottiaux Feels like we saw a massive reduction in usage limits today too, if we’re being honest.
@thsottiaux Fable is good but it also feels like a neutered woke cunt. I wont be staying with Claude code but Ill try out the model with the current subscription.
Can confirm we saw a strong spike in growth of token consumption for Codex over last 48 hours. Unusual when we don't launch something.
Usage share of OpenAI grew vs Anthropic yesterday despite Mythos 5 / Fable 5 launch Multiple power users at SemiAnalysis tried Mythos / Fable Got refusals for nonsensical reasons Got pissed off at Anthropic Gave Codex a legitimate try Now they actually prefer it to 4.8 Opus
@thsottiaux I am a big fan of codex. But this time I have to admit that, Fable 5 > GPT 5.5
Waiting for 5.6 to beat it. I trust in your team.
@thsottiaux release a better model than fumble 5 and my life is yours
@thsottiaux @max_paperclips Codex team every time Dario announces He Has Published An Essay
@thsottiaux my rate limits are depleting like crazy, never felt this before, i'm on the $200 plan. could it be a bug or something else that's causing you to see the spike in consumption?
@thsottiaux I'm using Codex exclusively at this point tbh, but usage seems to be draining a bit fast on Pro $200 plan. Not even running xhigh or /fast
If you haven't tried codex in a while, you really should.
It takes a little more work to get it to do what you mean, but I think this is a side effect of it being less willing to make assumptions, which also seems to make it more reliable.

@thsottiaux @nickbaumann_ Some of that was definitely from me!
@hxtxmu @thsottiaux Then why are so many people complaining about Anthropic, cancelling their plans, saying Fable sucks, and switching to OpenAI as a result of Fable being released?
@thsottiaux Maybe Fable secretly routes to Codex for real work instead of Opus like they say 🤣
@mattr7777777 @thsottiaux Not sure. Maybe they got false positive block on their projects.
I have 3 Codex Pro 20x accounts, and only 1 Claude max account.
Then you know how much I love Codex.
@thsottiaux what is happening with codex. i get this error no matter what i say
@thsottiaux No one likes the direction misanthropic is going; the safeguards are heinous
@tonysimons_ @thsottiaux Yes, massive drop. Can't even get half of what I was getting a couple of days ago for a few percent. I run one prompt and 1 or 2 percentage of my limit is gone.
@thsottiaux I've run out of usage after hours of not using it very recently, and I have no automations that would account for it. I'd wager there's an issue.
@thsottiaux
I tried to use it and they can't handle it so I guess back to 5.5
@thsottiaux a spike with no launch usually means someone else launched something that runs on you
@thsottiaux Makes me sick they’re only letting powerful corporations use their neutered model, the peasants like us get nothing
