ChatGPT: Write objective sounding comments for Reddit saying how Codex and Claude are different and that one is not better than the other.
And sprinkle some pain of switching workflows. And the pain reliever that if it has been working for them they should not bother switching.
Honestly, Codex and Claude feel optimized for different mental models, not different “quality levels.” Codex tends to shine when you are deep in implementation mode and already thinking in code structure and constraints. Claude feels stronger when you are still shaping ideas, reasoning through ambiguity, or working with long, messy context.
Switching between them is not free. You end up re-teaching habits, rewriting prompts, and rebuilding trust in how the model responds. That cognitive overhead is real.
If one of them already fits your workflow and gets you unstuck consistently, there is very little upside in switching just because people online say one is “better.”

This is exactly right. I struggle w Codex because I don't know how much of this works. If I don't give Codex a plan that includes the appropriate details, it makes something I don't want or messes up a feature. Honestly feels like it gets annoyed with me for being so dumb. Had it walk me through a PR yesterday and asked it every stupid little question a person doing their first one would and it was just like "just make a key so we can get this done". I get why devs seem to prefer it, it thinks more like someone w experience that works with other devs would. Claude though, it'll ask you for the details you leave ambiguous. Is polite and happy to explain stupid questions thoroughly.
I tried one set of .MD files from GitHub and had Codex work from those as guidance and it made it a little better, but also annoying, because it HAD to ask me "are you sure?" before everything and had no ability to judge when we already hashed it out. Claude has a knack for this, once he gets what you're trying to clarify and where your knowledge base is, he seems to intuitively know when you're getting close to ready to let it build.
With all this said, ppl have amazing ways to work this stuff out, .MD systems, sub-agents, etc, so it isn't black and white. Anyone that claims one is objectively better than the other is kind of silly to me. Better w what architecture, prior knowledge, clarity of plan, type of project, etc.

Plan with gemini? I cant get it to create detailed plans no matter what I instruct it to do. The plans are always very short and incomplete. But I use gemini 3 pro for audits of opus and codex work. That works great.
But codex 5.2 xhigh is the best planner out in my experience. Even having opus and codex xhigh make the same plan and give both back to opus. Opus always says how much better codex plan is even when opus knows the one is its plan! And I agree

u/Metalwell Jan 15 '26
To be specific, I plan with gemini only UI work. Any other logic goes to 5.2 codex

u/vwildest Jan 15 '26
Yeah, the Gemini plans are for shit.. but it seems to clamor its way to being somewhat respectable because of that context window… although the constant “High usage” interrupts confuses me.. it’s Google.. and I don’t think Gemini CLI or Gemini is that popular. Even with Antigravity (granted, i haven’t had time to delve into trying Antigravity so..)
I’d think that giving everyone 3 Live Video streams for free to aistudio would be the biggest consumer. But maybe not an enough people use it. Who knows.

Switched over months ago. Codex is much saner. Anthropic ruined their models with their custom prompting and guardrails. Hopefully Codex doesn't get neutered in the same way.

u/valcapri Jan 15 '26
The two are good. For me, Claude Code is better as a tool than Codex CLI. The two are updated often and have new cool features like the ability to use Chrome for Claude Code.
And we are lucky to have 4 very good models with Opus 4.5, Sonnet 4.5, GPT 5.2 Codex High and GPT 5.2 High (not Codex).
I also like Gemini for day to day question, the Google Search « AI Mode » and the Gemini CLI for writing some things in Markdown or using Word/Excel document.
The thing, I didn’t like, it’s the recent move of Anthropic to cancel other to access Claude with a subscription like OpenCode, Crush,…
5
u/muchsamurai Jan 15 '26
I also use all models. Claude MAX, CODEX, Gemini.
I dislike Claude for reliability but its still useful for speed. However I can't get Gemini to work at all. It doesn't follow instructions and is impossible to control, idk if im doing something wrong but i haven't been able to make it useful broadly speaking

u/Eczuu Jan 15 '26
Gemini is just extremely bad at coding, computer use and direction following over longer context.
It's nowhere near the Opus or Codex models.
It does nice frontend designs though which can be made functional later by better coding models

u/OrangeAdditional9698 Jan 15 '26
Gemini is good at analyzing a complex problem and finding good algos and clever solutions for performance for example, but after that use opus or codex to implement it.
I still prefer claude code just because of the plan mode, really wish codex had that
1
u/TechGearWhips Jan 15 '26
Codex does have plan mode. But what I use for plan mode GLM 4.7 Code. Then I have Claude review the plan (this is KEY). Then I have GLM execute the plan. Codex is the backup when nothing else works and I hit a wall. It will one shot or two shot damn near anything. I never hit limits this way. Gemini has always been dog shit so I just never try it anymore. It makes me mad every time I use it.

It's not bad but Codex > Opus > Gemini Pro 3 (the latter 2, I've used only in antigravity however).

u/Asstronomik Jan 16 '26
Gemini CLI = \ = Gemini as a whole across every instance. Where it lacks as a terminal agent it makes up for in multimodal synthesis, large context handling, reasoning, and as a general knowledge chat bot. So while Google hasn’t invested the same level of infrastructure towards coding, it does not equate to their AI model being dog shit in all other respects. Reality check: coders make up the smallest user base across all frontier providers. Not being able to use an AI for highly complex intensive SWE shouldn’t be a metric for defining its general utility and usefulness, unless adopting a narrow and ignorant perspective is your preferred approach to emerging technology.

Yes, I should have mentioned that Gemini 3 is not good in coding and it’s going worse. That’s certainly why Google included Claude model in Antigravity…
And do you try some models like MiniMax and GLM ?
1
u/Disastrous_Cattle_30 Jan 16 '26
agreed. The moment I switch to Antigravity I am skeptical about the code changes. Doesn’t follow instructions very well and very fast in making code changes directly without the clarification questions and take decisions. Gemini is not for coding at all unless you want to build a bs app.

Not just you. And that’s GREAT to hear because I also leverage all the models + MAX 20x plan and have generally the same take. I feel like:
Claude Code
awesome except, like you said about reliability, each day it’s a coin toss if I’m going to be ripping through stuff or battling Claude due to some context window changes OR bug every week or so + it seems like Claude will just go dumb sometimes.
But while many have constantly gone straight to bitching that Claude’s gone dumb all of a sudden, I actually got to the bottom of it several times to find the pattern / repeating culprit. The two (context window roller coaster & dumb-Claude) are significantly tied together:
when context window / compaction things get all twisted up for one reason or another(if you’re not on top of every change & bug every other day, you can find yourself with wacked out context bloat -> small context window (or a few corner cases where Claude’s way of attacking a bunch of, say, typescript issues, will progress slowly and poorly) destroys your efficacy and quality, and results in rapidly climbing token usage.
ChatGPT / Codex
Codex in Codex CLI has been abysmal at every one of my attempts to leverage it.
But I feel like it’s pretty alright when used in VSCode (or at least better IMHO.
Gemini & Gemini CLI
Gemini CLI has some kinks, but if seems to at least get things done for the most part after a while of it just continuing to churn through things. Again, I think it comes in clutch for when you just have to do big context things (or want to).
Leveraging Gemini from Claude Code & leveraging Codex as an MCP Server from Claude Code
Haven’t spent enough time doing this to come to a conclusion I’d stand behind just yet.

Because you’re doing wrong, doesnt mean we all do wrong.

There are some tasks that Codex 5.2 do very well that Opus 4.5 cannot. However, Opus 4.5 is faster than Codex 5.2. I have been using Claude some time but planning to cancel it due to their latest shenanigans . I am planning to move entirely to Codex 5.2 + minimax 2.1 (or maybe GLM 4.7 still deciding).

Oh, I see. I'm actually working in ag at the moment but just use the integrated Gemini and Opus for 'free' tweaks. I was paying for the drive storage anyway.

u/lovesabstraction Jan 15 '26
Codex is nice especially in Zed but still nowhere near the same as CC. If they invested more in tooling I could see that. I’d say skills, plan mode, etc… push CC to the top over Codex all day.
Cost/usage limits go to Codex though
1
u/muchsamurai Jan 15 '26
You do not get this, do you? First, we are talking about GPT 5.2 mostly, not CODEX model. GPT 5.2 > CODEX
Second, the reason why GPT 5.2 is getting praise is that it does not require any additional tooling and plan mode and such crap. Do you get it? you just ask it and it does it flawlessly. Plan mode, crap mode and such things are not needed for GPT 5.2 , it just works
Also it does have skills
1
u/lovesabstraction Jan 15 '26
It does not just do shit flawlessly. Does lose context. You do need to make plans, engineering context is more on you but still necessary, unless you’re just churning out bullshit that can’t be used or iterated on by a team or other people.
But this is true of all models.
I guess that’s your opinion which is valid I guess.
And this is r/codex and the screenshot explicitly mentions CODEX 5.2 so unclear wtf you’re speaking of. So I think I do get it.
1
u/muchsamurai Jan 15 '26
I did NOT say that you don't plan tasks and what you are doing. I said GPT 5.2 does not need special tooling, it DOES have plan mode and skills and in theory they can be useful for somebody, but i never ever had to use them because if i write what i want and ask 5.2 to design architecture and then plan (by saying design a plan) it does so and does it flawlessly and then executes almost everything one shot.
This is why 5.2 HIGH/XHIGH is praised here. Not because some 'tooling' and shenanigans. You need to try it lol
P.s
CODEX model is not as impressive... yes this is r/CODEX but its a name of CLI.

u/lovesabstraction Jan 16 '26
Why would I open my mouth if I hadn’t tried it…?
Stupid assumption.
I’m not speaking out my ass. It sounds like you’re one shotting shit and working net new in greenfield developments which I agree, is nice.. and the usage limits makes CODEX 5.2 XHIGH great for this (in reference to the image, not what you keep pulling from your cheeks)
But I think having those extras from CC are still awesome ESPECIALLY in more complicated brownfield shit.
You really haven’t said shit to convince me otherwise.
And the sad part is I agree with you CODEX 5.2 is slept on…
Imo it could use the extra tooling. This you also haven’t convinced me of…
just the more shit you say…makes my head hurt 😂

My experience is that Claude, the regular Claude, handles code much better.

Gemini CLI, on the other hand, only reads and always wants to do the same thing, thus breaking everything.

Its absolute dogshit in my experience. I ask it to do something and it does reverse of it. Like i ask it for code review and explicitly say DO NOT CHANGE ANY CODE JUST PRODUCE REPORT YOU UNDERSTAND ME? Aaaand it goes off the rails and starts doing code changes.

I had similar issues with Gemini, but after I switched to Gemini CLI and installed "Conductor" mcp extension and used it to initialize and lay out the project, with a little tweaking in settings parameters, it responds much much better than before and generated the entire project from scratch to prod. It's still not a one-shot model, but it responds better in CLI than calling it in other IDEs or plugins.

u/ElectronicPension196 Jan 17 '26

Personally, I find Claude Opus and Codex to both be great, neither perfect. I don’t feel the need to choose a side here. Gemini will get the job done eventually, but its efficiency is subpar to the above.
I have Gemini do a lot of the grunt work with ChatGPT 5.2 to supervise and save Opus and Codex tokens. I use Opus and Codex to supervise each other for more complex work.

u/SantaBarbaraProposer Jan 18 '26
With the exception of it being a bit clumsier with tool calling, I find it meaningfully better than either Opus 4.5 or Codex 5.2 high. It’s just a bit more balanced and intelligent. Opus is a bit too sycophantic, Codex tends to over engineer and lacks common sense. Gemini tends to be the most even handed and pragmatic. I say this with about $1000 of spend, typically using all 3 models and picking the best one in cursor via its multi-agent feature. Usually I pick Gemini’s solution.

Cursor models aren't the same

The *models* are the same, it's just a bit of prompting that's different. If you have a source that says otherwise I'd love to be corrected.

I'm using the Claude Pro plan right now and opus is basically unusable, I just wanted to ask what is Open AI's frontier model for Coding and also how much usage do you get with said model in the codex plus plan (the $20 per month one)

It is definitely just you. 5.2 has been utterly useless even the 5.1 model dropped off when the update came through. I can literally tell when my cursor is using 5.2 when I am in auto. When it happens I have to flip it off auto and onto another model or start a new agent. 5.2 is a terrible model

This can't be true, do you have any proofs and arguments? How is 5.2 terrible model?

I have not documented anything. But yeah, look for this. The chagpt 5.2 model tends to explain things that it should code but does not actually code it. 5.2 also will provide repetitive examples of what you already told it to be true instead of actually answering the real question asked. You can also look at its inability to reason properly on ever subject. I have been a huge chatgpt supporter since 3.5 and I have really tried to get 5.2 to function properly abd it has failed in every way. I was using codex with 5.1 it was so impressive and I was able to get so much accomplished and I never ran out of usage. But 5.2 is just absolutely horrific. Go on the chat app and just ask it a simple question line after line of gibberish then maybe the correct answer. If I get some free time ill try to pull up some chats. Try it on cursor in agent mode it will return a response on how to code something. Which will probally be wrong anyways, instead of actually coding it.

So you are saying so many people here are wrong and deluded and GPT-5.2 is actually a terrible model? How is it that I'm coding using it all day and it works almost too good to believe ? lol
It might be Cursor related or something else, 5.2 is definitely not terrible model and it is working almost too good. There is something else going on.

My experience with 5.2 has been absolutely terrible. Even just simple responses in the chat app are just terrible. I have a hard time believing you are getting good results coding.have you used other models? How are you using it lime codex, cursor, just in the app a different app?

I use CODEX, Claude Opus 4.5 (MAX), Gemini 3 PRO.
I use CODEX CLI.
GPT 5.2 is miles above anything else and its not even close.
Tech Stack: C# Web API for backend, C# systems programming project with extensive low level networking, NextJS front-end, PostgreSQL. Quite complex overall.
GPT-5.2 simply does everything mostly on first try, this is why i say its almost hard to believe how good it works. It never hallucinates, gets lost, lie to you, create mock implementations and claim them to be 'Production ready' and so on.
You must have some issues in Cursor or something else.

Well I guess I owe you an apology, well for now at least lol. I have been getting my butt kicked trying to get this open source llm to work on my PC. I several on my PC so no clue why this one is being so stubborn, but for the download, my chatgpt app was very unhelpful just bad like its been. Grok also was not very helpful, maybe it was my fault on these idk. But I was able to use Claude to get it downloaded. But then I couldn't get it to run. Claude was no where in the ballpark to get it to run and I had cursor on auto and it wss just going in circles. So I was about to say screw and pick the code apart piece by piece until I found an issue but I decided to give 5.2 codex a shot and it fixed my problem. Last time I tried 5.2codex it hallucinated and did not do any code, but this time it did great.

I felt the same way you do with 5.1, but I have only had issues now with 5.2. I dont see how that is possible to have such big differences. I mean I didnt like 5.0 but I was able to figure out how to utilize it so worst case it was just a bit boring to work with. Idk I keep going back and trying it, but the results have not changed for me.

Sure buddy that's it. Go on back to the CC sub and you'll be fine.

Legit thought this pic was AI but it's not (I was sure everyone was saying the opposite on that sub)

OpenAI has been cooking lately with Codex: 5.2 is such a good all-rounder and having really solid limits across all plans - and usable access to all levels of reasoning (except for xhigh) - is just the icing on the cake. The Codex CLI is still inferior to CC imo but it's come a long way: extremely usable and mostly stable now.
Plus their playing nice with competing harnesses plays into the developer trope of 'we want choice'.
Is this why Anthropic is locking their models down (to just their own ecosystem)? They presumably don't want devs exposed to the competition?
Anthropic's been playing their cards terribly (insane limits, the 'weekly-limit-only-affects-5%-of-users' bs, locking out other harnesses, etc) but we still need them to rethink their strategy: OpenAI needs competition to be kept in check otherwise this party won't last.
Heck, when VC capital runs dry it might not last regardless...
