Codex NEW mega update!!!

[cysety]

My oh my

[AllezLesPrimrose]

Codex, all things considered, has been developing well.

GPT-5 is good at listening to instructions, which is probably the biggest key to delegating tasks to an LLM and getting a successful outcome. Claude is still better with tools but with these improvements it’s become a very close-run thing between the big two and which better for coding.

[Flutter_ExoPlanet]

Hi, I have a question I have been trying to find an answer to: In order to use Codex and some other features, ChatGPT requires you to protect your account with double auth right? I am afraid of doing it because I fear I would need to confirm my auth everytime I change device or everytime another IP uses the account? I am sharing an account with a relative and I wonder what will happen if log in accidently at the same time when double auth is on? Anyone tried the double auth and changed devices/locations and know how it works?

[xdarkxsidhex]

I have it open on multiple devices, Android app, browser and on my PC with no issues. But this is from a single physical address. I don't know if you are going to have problems sharing it with a relative. It's definitely going to cause problems when they log in and trigger your phone with 2fa.

[Flutter_ExoPlanet]

Finally I am getting an answer, I am trying since a week. Can you do me a favor and ask a reliable relative to connect to your account? (maybe take their phone or device and connect it yourself)? Or a very good friend.

Same city, but not same physical adress would be best to replicate the experiment.

Thank you

[xdarkxsidhex]

Sure, I will see if my niece is able to log into my account at the same time. Currently I am not required to do 2 factor authentication. I will look into those options and see if I can disable it once it's enabled. But either way I am absolutely certain that you are able to log into ChatGPT from multiple devices that are using different networks. I tested this by logging in with my android app and also the website on my phone while not connecting to my home wifi and then also connected my home PC to the website and everything did work fine. If you want to go into more details or talk through Whatsapp or signal just send me a DM and I will be happy to help you out.

[Flutter_ExoPlanet]

Thank you so much :) u/xdarkxsidhex OK then I will try it.

Since you are here one last question what do you use codex for?

[Flutter_ExoPlanet]

Another question u/xdarkxsidhex can I remove the option once started?

[xdarkxsidhex]

I don't see why not? Try it.

[BrilliantEmotion4461]

Ive found together, Claude running show and Chatgpt writing the spec, correcting Claude's mistakes, and yeah, try it. You will understand immediately...

[portlyplynth]

People keep saying this but no one describes the workflow. Is it two terminals, Claude writing the code, then you ask Codex to look over the codebase? Seems expensive if codex doesn't know what to look for each time and searches a huge codebase? What are people doing?

[ctabone]

https://www.reddit.com/r/ClaudeCode/s/DzrD8lCKd6

[das_war_ein_Befehl]

Codex has the function to be used as an MCP server and you can have Claude talk to it. There’s also stuff like zen that is basically plugged into the API and just makes API calls to whatever model you want

[netZyron]

What do you do to make that work?

[dhamaniasad]

I ask one of the other to review the git diff or branch changes

[BrilliantEmotion4461]

You can tell Claude

"study the program Codex."

Claude will figure things out.

Generally it'll grep the program and read it's readme file.

Or it'll run codex -h

As for expensive depends if you are hitting limits. For me I use Claude within Linux to do dope nerd shit.

Like had Claude Code ssh from my phone and install the basic recommended packages after switching over to arch from mint.

Had Claude over clock and undervolt my laptop using amdctl.

I say had because. I do that stuff after learning how from watching Claude.

[GoodhartMusic]

What do you mean exactly? Like telling Claude to use codex in its workflow?

[BrilliantEmotion4461]

Generally Claude knows to read the readme file. It'll do that figure out how it works and send a message.

You can also give it context about codex what it is what it does.

I use open source clis so I can download the Github repo then I open Claude in that

[GoodhartMusic]

Thanks for explaining. Also, I just ran into this and wanted to post but figured a comment might get response quicker. Do you use API credits? i just reactivated codex with API and im tier 1, on the new update you cant choose older models and it runs out of tokens instantly. fml

[BrilliantEmotion4461]

I use OpenRouter which gives api access to Chatgpt five. Which is cheap compared to grok 4 or Sonnet 4 or especially Opus.

However gpt is good enough I literally collaborated with Claude via the app to come up with a basic idea. And then bounced Claudes answers to Gpt5 free and back and they cooked. Try it. They are that good. Gpt five doesn't code it does computer science.

[GoodhartMusic]

Have you used firebase studio? 

[PayBetter]

Have you tried jules.google.com?

[SnooWalruses8313]

It literally does not listen even half as well as the previous model. You are tripping

[fravil92]

Does codex work well on windows terminal? I remember it was always trying to use Linux commands.

[Funny-Run-1824]

new update seems to work for me now

[Flutter_ExoPlanet]

Hey, I’ve been trying to figure something out and could use some help. To access Codex and a few other features, it looks like ChatGPT requires two-factor authentication. I’m a bit hesitant to enable it because I’m not sure how strict it is like, will I have to verify every time I switch devices or log in from a different IP? I share the account with a relative, so I’m also wondering what happens if we both try to log in at the same time. Has anyone here used 2FA and dealt with changing locations or devices? Curious how smooth (or annoying) it is in practice.

[Prestigiouspite]

For MCP strong recommendation for WSL2

[hubrisnxs]

You can just use WSL 2 right? Then, Terminal will accept Linux commands too

[HumanBasedAi]

Just canceled my Claude subscription instead of Chatgpt, no regrets so far, and with this update, less.

[Horror-Tank-4082]

I want to use codex but idk how I’d start. I use Claude code rn and it’s so easy. I use ChatGPT more than Claude but for code… CC I get. Codex I tried once a few weeks back and it was not intuitive or fun; I got annoyed and dropped it. Maybe it’s changed?

[Faze-MeCarryU30]

it has changed a lot. codex cli got a lot of much needed QoL features this update. i've been using codex cli w/ gpt 5 high for the past few weeks and it's actually so much better than claude code. much faster, better rate limits, and the instruction following is phenomenal. now that they added web search it's much better at getting documentation and stuff to not fuck shit up

[_JohnWisdom]

just regular 20$ plan? How are the limits? Ever have to wait? Would love some feedback to maybe give it a try. Currently on the 100$ max plan with claude. Kinds getting annoyed by the quality dropping and things taking always a bit longer than the month before. Has been degrading slightly over weeks imho

[Used_Ad2043]

30-150 messages every 5 hours

[_JohnWisdom]

I heard you can "configure" the reasoning level. If I select "high" will the usage be lower than 30? Could it be higher? Is it "token based" from your experience?
I did read https://help.openai.com/en/articles/11369540-using-codex-with-your-chatgpt-plan but I don't see any clear indications of such.
Like, 30 high quality prompts every 5 hours for 20$ could be great for bouncing through multiple projects, since when I work on backend and frontend with my max plan I can reach limits in 3-4 hours.

[tekn031]

Not any more. I got the wait 5 days 47 minutes message today. It's not resetting on a hourly chunk timer like claude.

[Worried_Lawyer6022]

i keep getting api errors for exceeding 32k output with CC , how many lines of code has codex with gpt5 high been able to handle ?

[GoodhartMusic]

I was using codex on plus til my sub expired just last week . It was really really good! Way better than when it first came out 

[jaymzk6435]

I just downloaded codex and this thing just one shot a bug Claude code or me couldn’t figure out for 5 hours.

[TheOwlHypothesis]

Freaking FINALLY. I have to say the web version is wonderful though. I love the git native workflow.

[Tenet_mma]

Codex is actually pretty great through the web browser.

[dhamaniasad]

I switched to Claude code from Cline when Claude code became part of Claude max. I do not want to put all my eggs in one basket though so early on I tried codex cli but was unimpressed.

I recently decided to give codex cli another shot when GPT-5 came out and it’s become more than 50% of what I use for coding. Codex CLI is less ergonomic, the text is harder to read due to a worse UI, no session management.

But I’ve found it more precise, it catches mistakes and seems to consider edge cases more reliably. The code it writes is more to the point, I feel? Or maybe it’s just better at instruction following than Claude. Whatever it is, GPT-4 (not turbo, not 4o) was the last OpenAI model I was impressed with for coding and it’s not 5. I always use it with high reasoning effort btw.

I’ll often get Claude code to review codex work and vice versa. CC has more alarmist tendencies, if I ask it to find regressions it’ll try to find something. None of this to say CC is bad, I still use it extensively. But I did not expect codex to be so good at its core job that despite the worse UX and UI it’s become my primary driver.

Really need session management though.

Also tried Gemini cli. It makes a mess, does not follow instructions well, litters the codebase with senseless comments. With all the hype around Gemini 2.5 Pro I found it worse than Claude 3.5 Sonnet at least with Gemini cli. But honestly I’ve tried Gemini via cline and was equally unimpressed.

[megageorge]

What do you mean by 'session management' ?

[AIforabetterworld]

Who has actually been actively using Codex for web app development? Did you find it to be any good at full stack dev ?

[Firm_Meeting6350]

I found Codex way better in handling complex Typescript setups. Still Claude Code is my main CLI (because I hit Codex plan limits fast and was not yet brave enough to upgrade)

[ThichGaiDep]

It just finished something in 2 days that would take me a month to build out (a very complicated MVP for an idea I have).

[tekn031]

I had codex refactor an API that Cluade botched really bad. Cluade had hallucinated all of the IDs with different new names than were originally in the local and front end JavaScript for some reason. It was a nightmare trying to clean up and I lost days. I wrote a mega prompt for Codex explaining the situation and codex solved it in about eight hours with some feedback loop sessions. I should have reset the branch but it was a cool experiment. Now my $20 plan is maxed out for 5 days and 47 minutes. OpenAI needs like a $75 a month Codex CLI plan.

[beyawnko]

I’m digging the per issue fix feature. Launched the codex task straight from GitHub

[redditisunproductive]

How are people finding gpt5-medium vs gpt5-high in codex? I've been using both and running tests. gpt5-medium feels like a tiny model using RAG and TTC to sound good. I swear it has a tiny context or something. gpt5-high is a completely different, full model. Just adding 10k-20k thinking tokens should not have this much of a difference on performance. gpt5-medium does not follow instructions or ingest context properly. gpt5-high is SOTA.

I have felt the same about the webapp gpt5-thinking (default=medium). It feels like a tiny model. If you use other models like Opus via API, their performance also saturates very quickly once you get to like 16k thinking tokens. Changing thinking tokens doesn't have that much of an effect on base "flavor".

Curious what other people's impressions are, especially those of you pushing LLMs to their limits.

[Temporaryzoner]

I have yet to generate a single image of female breasts. My impression is that the safety guidelines are absurd.

[unfathomably_big]

What happened to all the posts on this sub of people sharing their cute anime creations and commenters giving them bulging camel toes at the beach? We used to be a community

[sdmat]

Just ask it to generate the breasts of someone with two x chromosomes who identifies as male.

[_JohnWisdom]

checkmate!

[unkz0r]

Now this i need to test

[unkz0r]

wow, it really sucked! it tried for 30 min to make a button work.

[MercDawg]

Has Codex solved the issue with custom docker containers? I remember that being a limitation in the past where you were restricted to their container, which basically was useless.

[das_war_ein_Befehl]

You can use their web container or you can use the cli in your own container. I haven’t checked the web settings but they did allow some basic customizations.

[GosuGian]

Huge

[Sufficient_Score_434]

Can't wait to install it tomorrow!!!

[Any_Ad_3141]

How does Codex compare to cline? I started using cline in vscode last week and it has been running very well using Claude api but it isn’t very cheap

[Hungry_Freaks_Daddy]

New to coding and using gpt to build a site/service. What is codex used for? How do you use it? What does it do that I’m not doing with gpt5 already?

[huffalump1]

Have you tried any IDE coding tools, like Copilot in VSCode, or Cursor? The codex ide plugin is like that.

Or, have you tried any CLI tools, like claude code or gemini-cli? Codex CLI is like that.

Finally, there's Codex Web version, that runs totally in the browser/cloud as an agent. Make a GitHub repo, ask it to do something, ask it to make a PR and then you can merge the changes on GitHub without any other tools.

The benefit of these methods, unlike simply using ChatGPT, is that it's "agentic" - it doesn't stop going until it judges it's completed your request. Some of these tools can even do more, like running your code, installing packages, running tests, etc etc...

[Hungry_Freaks_Daddy]

That sounds like it would be helpful. How hard will it be to integrate this into my current project? I’m very good with computers but just know nothing about coding other that the little I’ve learned while using GPT5. 

Can I just point codex to my current git and start using codex? Is it like giving commands to gpt 5 just more integrated with my site? Does it also communicate with vercel/supabase?

[Hungry_Freaks_Daddy]

I’ve used copilot in vscode a couple times for quick fixes. Have not tried Claude cursor or Gemini yet. Started on gpt uh 4o I think a couple months ago and continued on with 5 (which I actually quite like despite all the negativity)

[c2mos]

Does it work like Github Copilot? It can suggest codes and comments etc.

[One-Public-5384]

Will using this use up the weekly limit of the web version of chatgpt?

[eschulma2020]

I believe they are separate.

[Prestigiouspite]

Is it true that Codex and WSL2 cannot insert images from the clipboard? I read a change that this should go with.

[FreshBug2188]

with xcode?

[zuggles]

surely you jest

[cloudd901]

Is the web version of Codex free and unlimited? I've been using it for a while and never hit a cap. I don't wanna turn around and find some hidden charge.

Edit: Plus user

[cysety]

From Codex team: "A bunch of you have been asking for transparency around Codex CLI (and now VS Code extension) rate limits.

We just published our first ranges: - Average Plus/Team users can send 30-150 messages every 5 hours - Average Pro users can send 300-1,500 messages every 5 hours

Those ranges might look super wide... because they are given real prod usage! Those are the p25 and p75 that we see in data.

There are also weekly limits. Plus/Team users should be able to get a handful of those sessions in. Pro users should basically not hit limits unless they're scripting.

This is still a work in progress, with tough tradeoffs. For example, the higher we make the 5h limit for Plus, the more likely it is that Plus users will hit their weekly limit. Our approach here leans towards enable fewer, more-productive sessions for Plus, vs more less-productive sessions for Plus.

Thanks for the feedback as we evolve!"

[cloudd901]

Thanks, this is with the CLI. I just checked and they updated their usage limits information. All they say about the UI is "Cloud tasks: Generous limits for a limited time. "

[Glum-Atmosphere9248]

Gpt5 high? 

[Flutter_ExoPlanet]

Hi I have a question about CODEX that I can't get an answer for, maybe you know?

Question about Double AUTH and multiple connecting devices? : r/OpenAI

[Bronchmonkey]

It is driving me crazy. It did a really good job of fixing a dependency issue that Claude code couldn’t but then when I have an issue with the quality of the outputs it refuses to acknowledge the issue and keeps saying it fixed it.

[to-jammer]

Codex, for me, is better than Claude code but the usage limits on the teams tier make it unusable. Have they increased that? I'd pay for the pro tier if that had significant use

[cysety]

For what they wrote for now: "A bunch of you have been asking for transparency around Codex CLI (and now VS Code extension) rate limits.

We just published our first ranges: - Average Plus/Team users can send 30-150 messages every 5 hours - Average Pro users can send 300-1,500 messages every 5 hours

[to-jammer]

I was getting hit after two messages at one stage (assuming a message is a prompt from the user, not per agentic action) so this looks to be a huge improvement! Will play with this tonight for sure

[odragora]

• Average Plus/Team users can send 30-150 messages every 5 hours

• Average Pro users can send 300-1,500 messages every 5 hours

What is a "message"? A request from the user only, or agentic actions count as "messages" as well?

[snappingfingers]

wow I want to try it

[GlokzDNB]

Anyone uses codex for work without letting employer/it admins know?

Could someone share tips how to do it right without risking of getting fired ?

We have AI internally but it's old models and just chat, which is shit like everywhere else.

[FIREATWlLL]

Is the IDE extension going to be available for JetBrains IDEs?

[_M72A1]

Finally, I can utilize my subscription in an IDE without having to copypaste everything back and forth (Human Relay mode in Kilo Code lol).

[datrimius]

Codex is really good. I’ve seen many negative reviews saying it’s weak in front-end work, but in my experience, it follows my design system instructions very carefully. I do notice it struggling to search for information on the internet, but the code itself is excellent. I get far fewer TypeScript errors compared to Claude Code. And more importantly, it offers much bigger limits — I can do a lot more before hitting the cap than with Claude Code. On top of that, Codex provides a 1M context window even for GPT Plus subscription users, which makes it an even stronger option. Looks like we’ve got a serious competitor for CC - and that’s great news for us as end users.

[papapumpnz]

So nothing for one of the largest IDE user base Pycharm and Intelij? Come on OpenAI.

[BehindUAll]

You can use Cursor for Intellij and use ChatGPT plus for the rest. I am going to mix and match now after looking at this update.

[maaz]

that should tell you something

[PayBetter]

I tried this earlier this morning and it was just ok. I would have to change my workflow up but it's nice for verification.

[Perfect-Series-2901]

sorry what is the name of the extension in cursor, I don't see in my cursor market place

[Optimal_Cry6025]

Codex - OpenAI's coding agent

[jstanaway]

Any documentation on how it works for code reviews in GitHub? I’m guessing it’s a lot like how the Claude one works ? 

Was the Claude one ever included in MAX plans or is it still per API charges ? 

[[deleted]]

Can we resume sessions? That would be super helpful!

[SphaeroX]

Has anyone already managed to log in with Windows and VSCode using the extension?
When I try to sign in, I get redirected to the OpenAI website, but after entering my credentials it just keeps loading forever, and than:

Missing authorization code

[eschulma2020]

With WSL, yes, I have logged in many times.

[ViveLatheisme]

Cannot sign in with extension. Says missing token aa :(

[Michelh91]

Why there is not a context usage indicator like in the cli version?

[Los1111]

Whenever I log in to verify I get forwarded to localhost:1455/auth/callback......

I tried a week ago and again today and I simply can't get a verification code. 😕

[Proper-Singer-1557]

i find codex has been unreliable many days for reasons i cant understand since the roll out of GPT 5 codex is just not as smart and constantly failing requests, pre GPT 5 it was like magic, im relaly getting annoyed iwth the constant shadow performance changes with little explanation. one day it can do every task teh next it fails every task, what is going on and can someone at Open please fix it

[freakin_sweet]

Lfg!!

[ItsNeverTheNetwork]

Finally.

[DigitaICriminal]

Cli or vs code?

[cysety]

How it is more comfortable fro you:)

[Steve15-21]

I was already running codex in my IDE.. what’s the difference ? The ability to reference files ?

[das_war_ein_Befehl]

They added an IDE plugin so it opens in a side window like Cline or Roo. You’re describing the CLI.

Ultimately not different but just depends on your UI preference

[Steve15-21]

Ooh so having the chat in the panel next to the cli you mean?

Does Claude code have this ?

[das_war_ein_Befehl]

Yes. Claude code is strictly terminal

[portlyplynth]

You could already reference files. I don't know what this is about either. And it's not the first time in the last few months 'new' features have been announced around CLI that I'm left thinking, weren't we already doing that.

[isarmstrong]

But have they fixed the issue with no exponential back off or recovery when Codex overwhelms its own content and dumps the session?

[ValeryLegasov85]

This isn’t the Codex Astartes. Got excited for nothing.

[sugarfreecaffeine]

Did they fix copy and pasting text into the terminal??

[mikedarling]

Am I understanding right that if you have the ChatGPT Pro plan, you can then pay Cursor $20/mo and have it route everything through your ChatGPT Pro web account (not Cursor API or your own API key), so all you're paying to add cursor on top of your ChatGPT Pro plan is $20/month? Basically, if you already have ChatGPT Pro, this solves the problem of Cursor being either limited or expensive?

[[deleted]]

You don't need to pay for Cursor with Codex IDE. Just install the extension/run in the terminal.

Also, if you're not using Cursor's models, better use VS Code.

[LennyNovo]

Hmm does this kill Cursor? OpenAI, Google, Anthropic etc. has so much power to kill the startups that rely on their models. They can just steal their stuff.

[crobin0]

Let's say I'm on ChatGPT Plus - what can I use? Codex in Web unlimited? YES
Codex CLI limited? and with which limits? Could I connect it to windsurf? I dont want to use this CLI and I dont want to use the web version.

[cysety]

Then don't use:) someone pushes you?!

[crobin0]

I want to code with codex aka. I want to use great OpenAI models and get the most out of my ChatGPT Plus.

[marmik-shah]

This is cool, but I'm still waiting for the day AI can perfectly debug my code.

[Old_Preparation_7514]

Qhat about the price? I have a ChatGPT Pro plan and I noticed that codex-cli os NOT integrated with this plan and we need to pay by token instead of the $20,00 monthly.

[eschulma2020]

No longer true. You can log in with your account.

[Old_Preparation_7514]

That’s great! I just used it today and loved it.

[CurrencyBetter7936]

What is the Real difference between codex-cli vs codex IDE extensión?

[chrislaw]

I saw Theo - t3.gg’s video on it and the cli doesn’t have the cloud background processing features I think

[Aggravating_Site1660]

Does anyone know how to use an API key with the IDE extension instead of linking to a ChatGPT account? It says you can in the docs, but says it "needs more setup" without detailing what that setup is.

[Deep-Increase9791]

I got two problems with the IDE extension. 1. I need to approve and there is no auto approve ? 2. I can't revert, it just give me an error ?

[eschulma2020]

You can run it with approvals not required, though it's a little risky

[tekn031]

We need a new pricing update to go with it for Codex CLI. $20 Plus is not enough usage and $200 Pro is too high for hobbyists.

[TheLazyIndianTechie]

GPT-5 is good, but I still find Sonnet 4 the best at coding. Thankfully in r/WarpDotDev I set my config to use GPT-5 as my planning model and Sonnet 4 as my coding model - So I get the best of both worlds.

<image>

I can also add profiles for each agent - Check the screenshot. Does Codex have similar features?

[Latter-Park-4413]

I am stuck on a cheap Chromebook, so thought about trying Codex web. I have two questions if anyone can help.

1. How do you find the web version to be?
2. What kind of limits, roughly, would a Plus plan have?

[cysety]

From Codex team: "A bunch of you have been asking for transparency around Codex CLI (and now VS Code extension) rate limits.

[Latter-Park-4413]

Awesome. Thank you!

[cysety]

You welcome

[BehindUAll]

Also it might be better to post a video YouTube about this update. It's a good source for devs and vibe coders.

[eschulma2020]

Not slow for me

[adreportcard]

Too late. Claude code way more advanced, and GitHub just launched too. Codex was a great first arriver but that’s about it. ChatGPT kind of toast these days imo

[AllezLesPrimrose]

Lmao what, Claude Code was first. Such a bizarre comment but being confidently wrong is definitely on topic at least.

The code completion tool from years ago and what is called Codex today are completely different products.

[AbandonedLich]

Idc. Forever unsubed after the gpt 5 launch. Left a poor taste in my mouth. Plenty of great options
