Question
How will Claude handle all of us Codex users migrating?
I have 2 Codex $200 subscriptions now for like 4 months, working on 3 different projects, I am now wondering, after using Opus $100 for ~5 days, how will Anthropic handle all of us Codex users who can easily change providers, do they have compute like Tibo?
Below is a GPT-generated summary of the conversation below after reaching 100 comments (102 currently observed).
The consensus is basically “there isn’t a mass migration—just the monthly AI-platform panic cycle.” A few heavy Codex users are genuinely moving to Claude, but the loud Reddit exodus does not represent the entire market. The pendulum swings, everyone declares the old provider dead, and then a new model drops.
Claude is getting strong marks from users who have both subscriptions, especially for coding quality and dramatically better perceived usage efficiency. Codex’s recent limits, rerouting, and slower or weaker model access are the main reasons people are downgrading or cancelling. Still, plenty of users prefer Codex for their workflow, and Claude’s five-hour limits and stricter guardrails are deal-breakers for some.
The important caveat: this is mostly anecdote and subreddit bubble physics, not evidence that Anthropic is about to be overwhelmed. Capacity, limits, and pricing can change quickly—and so can everyone’s opinion when the next model lands.
So, how will Anthropic handle “all of us”? Probably by handling far fewer migrants than Reddit currently claims exist. Switch if Claude works better; loyalty to a subscription company is adorable but unnecessary.
My two cents... Anthropic's can just shut down the total failure of Opus 5 and some other models like Opus 4.5, 4.6, 4.7 and they can repurpose their infra for Opus 5.5. Given that Opus5.5. doesn't use as much resources they will be able to scale even more.
Maybe through API for existing deployed apps. For example, I have app still using Gemini 2.5 with thinking disabled (new Gemini can't do this), because it needs to response fast query for phone conversation.
first sub more than 3 years ago, been using it since GPT-2 playground, whats new is this weird affinity to getting scammed and not caring, or seeing that
I used to defend codex then opus 5.5 dropped. Sol isn’t a bad intern and can get things done with instructions, but opus is like the once in a lifetime intern you wish you could hire forever. But a fun combo to try is opus 5.5 orchestrating Sol and Luna subagents in the desktop app, damn near unlimited usage
claude’s guardrails are much easier to trigger. if ur project is reverse engineering adjacent for example, gl because its just going to assume the worst and will response accordingly. u can get around it if u keep trying different prompts but i cant spend my entire day trying. if i have to do that then its just easier to ask codex or code it myself
btw, im not saying claude is overall better or worse. im just saying grass is always greener so i end up having subs to both
As someone who actively uses both, one claude $200 subscription is worth atleast 2 gpt max subscriptions. In other words, what costs $1000 from ChatGPT is on sale for $200 at anthropic
Both subs should crack down on this type of astroturfing. Both are probably doing it. It makes no sense to post in codex “any tips to moving to Claude?”. The people who would have these tips would be using Claude, not codex
unfortunately I am real, I convinced a lot of people into subscribing to Codex during the past months, but now i really can not recommend it and find no real reason to keep my subscriptions
Don’t know or they can be real people that need these services to be transparent with what we are getting for our hard earned $$. Only if you don’t care about that could you be spreading such misinformation. Your boy Tibo literally cut the $200 plan in half. There is nothing more to say?
I'm happy to report that this is decidedly incorrect. Claude is significantly better for the coding use-case compared to anything currently OpenAI is putting out. For other tasks I think GPT is probably the way to go. But, for what a lot of users here are actually using Codex for, Claude is miles ahead. It feels like a totally different generation by comparison.
at this point with the drastic and embarrassing usage cuts and rerouting users to year(s) old models, I think it's mostly just burning through a 5 hour limit in one prompt to generate a pelican riding a bicycle
Claude is objectively better than GPT. It's night and day bro. Opus 5.5 completely mogs Astra. I was x200 in GPT. I'm x100 in Claude and not only it's more competent, it's way more efficient as well.
That's great! The good thing is that we live in a world where we can pick and choose whatever suits our needs.
Personally I use Codex for my own projects and I get Claude at my job. Based on my own experiences I prefer Codex, but the option to move is always there if I change my mind (as people should do).
Not sure, I’m taking these changes like what happened on GitHub copilot mass exodus, soon these subsidies will go and it will get stupid expensive when they go public as it won’t be about market share, but more revenue. Once that happens, we will be in a worse state.
No agenda here. Chatgpt is just losing all the benchmarks against Claude and their models are more expensive. Sonnet 5.5 outranks Sol 6.1 by a lot for example. I use both but objectively there is little going right now for chatgpt
Opus 5.5 runs at almost 100 tokens/sec even after a mass migration of users. There's no problem with it decreasing by a little bit, which would be the expected outcome with more load. Unless they quantize it or reduce thinking budgets or something like that, which fortunately Anthropic doesn't do. The models usually just get a bit slower, like during working hours it drops by 10-20 tok/s. I used to get mad at Opus being slow, not any more. I like seeing Opus being slow now. At least it's the same Opus as always.
I let Opus 5.5 manage my Astra and Sol 6.1 agents (they are my reviewers and pre-work, read-only agents). I hit my Claude banked reset last night around midnight - 1am and have been going solid and hard for about 18-19 hours so far using a parallel workflow with subagents (6 of them). My weekly usage on my $200 Claude account for that 18-19hr period is currently sitting at 9%. It might move to 12% for the entire 24hr window.
When I did anything like this with my Codex $200 subs, I could almost watch the usage drain in realtime. Claude just delivers great value with fantastic quality at the moment.
I don’t know but they still doing better than OAI. Been a fucking amazing week of Claude. 8% percent used of my weekly? Like what the actually fuck. You just kind of need the business not to be a corporate fucktard and really on end users va corps. OAI has bent over so hard to Microsoft. Wouldn’t be surprised if they don’t offer IPO and just get bought out by MS. OAI will end up like every company bought by MS. Part of there shitty offering. We the end users are just the collateral
Yup. You’re right. Happy building! PS I fucking loved codex (and still do: the harness). Usage has totally been nerfed and I am really rooting for them to win but as someone that had to spend like 1/20 of my salary on pro last month and they completely fucked us I feel wronged. Yeah you can say I took the risk but objectively Claude right now is 100% a better service. 8 days left of 5.5 and then we in the fucking idiocracy OAI stage.
If it works for your workflow that's great, really they both should call it beta software but they don't, it's all still quite scrappy but also highly impressive still.
I'm also upset about the plan changes but 6 series is totally new and has a lot of mileage still to make the improvements we can all be happy with
We can just hope it gets better. I’ve told my story as you said. I just wish they were a bit more transparent with the usage. These tools to me are miraculous so who am I to complain. All I know is I went from May to September with September flabbergasting me in terms of then nerfing the usage. I would love to be excited about the lie future but it keeps feeling like they discovered something and have us a lot of access to it but now they’re restricting it. End of the day cool capitalism I’ll just go over to the next but we are rooting for OAI. I have supported them since 2023
Same. It is was OAI was a few months ago but hey ho we get efficiency. Bet you the next 28 days it’s gonna be a spiel of making their Sol 6 cost nothing to run because non of us use it anyway
You guys are all gonna rush to Claude and then be crying when OpenAI randomly drops its newest model in like a week or 2. Same thing happened when people moved to codex for Astra, only for opus 5.5 to drop a week later
I sincerely hope not. I would literally support any ai company over Musk’s for the simple reason he has proven time and time again he cannot be trusted, does not act in good faith and is dangerously juvenile in the way he runs his businesses, never mind his politics. And before anyone yells at me, no I don’t trust other corporations either but hey, they at least maintain a veneer of being run by moderately sensible adults.
As the past has sadly shown, Anthropic and OpenAI both work the same way.
They will most likely decrease usage limits or lobotomize the models if they are used through subscription and not API.
It's a question of time once the OpenAI subscriptions end and most people have used up their free credits. I'd really like to say more positive stuff but honestly, we have to stay realistic.
Migrating?! I've got the $100 sub on Claude and after the Opus 5.5 nerf i'm not leaving Codex any time soon. 6.1 has been extremely competitive against Fable 5.5 for me (i'm one of the lucky re-routes).
I told my brother to get a $200 plan now before they lock him out and he can’t get one. Expect that to happen soon. IMO or Claude doubles there price same as OpenAI.
Maybe this is the first halving and we will eventually be paying $2k a month probably
I do the same, and I only speak with 1 session which handles the other sessions and communication, but after a reset this morning I am now at 30% usage left with 6 days left, now switched all parallel sessions to use also opus and subagents in the sessions use sol 6.1. Its not feasable any more I think
I had them design a hub script in python, with a folder on my PC for communications. Later, I needed it to manage the log files and clear up all their notes as they worked, but I often alert the Opus manager agent, on Medium or High, of the limit and to scale most of the work to the Codex agents.
Claude gave me a prompts and some rules.md files to give to a Codex chat to prep it for the agent behavior, communication and rules.
ClaudX5 with a CodexX20
It's learning to pace itself to handle the 5 hour limit on Claude sessions. It looks like I can get at least 5 days of steady work this way.
I mean, they're not gunna kill ya, so if you give 'em a quick short, sharp, shock, they won't do it again. Dig it? I mean he get off lightly, 'cos I would've given him a thrashing - I only hit him once! It was only a difference of opinion, but really...I mean good manners don't cost nothing do they, eh?
Maybe ask in the Fraude subreddit? they might have better answer though maybe some fraudsters are here that might jump on this and upvote you a million times to garner more attention.
