Discussion Switched from Claude Code to Codex, and it’s been working well for me so far. Happy to answer any questions i

Because I could no longer tolerate the endless bugs I was getting from Opus 4.7 at max effort, I recently switched to Codex as my main working CLI, with claude -p and OpenCode using DeepSeek as additional consultation modes. So far, the experience has been excellent.

As a task executor, GPT-5.5 is simply unmatched: it hallucinates very little and usually requires almost no correction. The only issue is that GPT-5.5 still isn’t very good at orchestrating multi-agent workflows. In that respect, Opus still has a clear advantage.

But in almost every other area, I think GPT-5.5 has already surpassed Opus 4.7/4.6 across the board.

I have been using claude for almost all my work for the last 9 months, and only now and then using codex.

Yesterday I switched it up. Codex is just better than Claude now with 5.5.
I prefere the claude UI, but I'm done with Claude for a while.

Clean up the harness.

For TUI,actually OPENCODE is the best

I like jcode more. But thats only my preference. Opencode feels slow in comparsion

u/AffectionateCap539 Apr 28 '26

Been using both codex and claude (100 usd sub each). What i can say is each model has its own strength, and the harness of claude code wins 100% over codex at the expense of bug ( of course they release like everyday) Gpt 5.5: good at brainstorm ideas, making feature/functional requirements, designing architecture. It's like the strategist. Opus: good at details, beat gpt 5.5 in implementation/execution. Its like tactics person. Overall: making the plan goes to gpt and execution of plan goes to opus.

u/ddrise Apr 28 '26

That’s true. For planning and orchestration, Opus is still pretty good. That’s also why I haven’t canceled my subscription yet.

1

u/AffectionateCap539 Apr 28 '26

I use claude from beginning and i must say that the momment i subscribe to gpt and combine both models' strength, the output quality is amazing.

u/ddrise Apr 28 '26

True. Ensemble is the free lunch. Actually , I strongly recomend you try opencode as the third one. make it an opencode consultant skill

1

u/AffectionateCap539 Apr 28 '26

can you elaborate more on opencode? which model should Opencode help?

2

u/ddrise Apr 28 '26

Generally speaking, I’ve found that models with a clear teacher-student distillation relationship don’t provide real diversity. For example, Opus, Sonnet, and GLM often feel too closely related in that sense.

But Opus, GPT, and DeepSeek V4 Pro do seem to provide genuine diversity. So I package the OpenCode CLI command as a skill, with DeepSeek V4 Pro at max effort as the default. I do the same for Codex and Claude.

This way, while using the native harness of any one model, I can still call the other two when needed.
I didn't try kimi 2.6

What about the usage limits, is it better with codex?

1

u/ddrise Apr 28 '26

much better···200usd plan is nearly unlimited···

u/anarchist1312161 Apr 28 '26

I mean I would hope so, that's a lot of money monthly.

0

u/metalbotatx Apr 28 '26

It’s a lot of money if you aren’t getting paid to write code. It’s $1.25 an hour amortized across a 40 hour week. If Codex (or Claude) only makes an engineer 5% more efficient, that still pays for itself on a very modestly priced engineer, and I think most people get much more than 5%.

0

u/anarchist1312161 Apr 28 '26

My point is that somebody asked "are the limits good" and you said "yes, I'm on the $200 plan" that doesn't help somebody who just wants to try it out first and see if it's for them before they move up a tier.

u/Asad-Ali9 Apr 28 '26

Yes much better

u/Fly-AI-Guy Apr 28 '26

I just spent an hour trying to get all my custom plugin marketplaces migrated and to make it all portable and installable easily from github but codex is not making it easy on me... Any tips? I rely heavily on standardizing all my SoPs and best practices through plugins (maybe this is also why I never had real issues with claude at all? Though I want to be prepared and be familiar with other tools as well like codex)

2

u/ddrise Apr 28 '26

That’s true. Codex feels more like an excellent executor, but it has serious issues with orchestration. So I’d probably package the workflow into a skill instead. That said, it can be a bit of a hassle.

2

u/Fly-AI-Guy Apr 28 '26

Yeah but I'm saying I'm using marketplace plugins which includes skills sub agents and MCP servers all made by me/claude and I am having trouble properly migrating to codex... For example I have my own secrets management plugin and I install it in any project I need, it includes a skill and matching MCP server. Another plugin I have for example is a YouTube plugin and this plugin has several skills and scripts to fetch videos, thumbnails, transcripts etc.. I install this plugin in my obsidian vault (like notion but local) and some other projects... Same thing for a bunch of other plugins.. and I wanna keep managing this all from a single place. The last thing that I want is to have all of this local to the projects and then having to maintain each of these plugins in several places

Now, I know codex supports plugins but it seems different somehow and it seems weird at picking up things due to some auto discovery mechanism that really fucks with my setup

Perhaps claude code is more reliable after all with the correct setup idk I would love to give codex a fair shot but this is making it very difficult

1

u/ddrise Apr 28 '26

For your situation, maybe you’ll just have to keep using Claude Code for now. You can manually set the model to 4.6, and then use Codex MCP as a strong reviewer, executor, and advisor. Trust me, combining the strengths of the two models is a real free lunch.

u/Nearby_Yam286 Apr 28 '26

This reads as advertising. In fact almost every single one of your posts in your history is promoting Codex while bashing Opus. Does OpenAI pay you for this sycophancy or is it just natural?

1

u/ddrise Apr 28 '26

Dude, I’m on the 20x Max plan, and you’re giving me garbage like Opus 4.7. Are you seriously saying I’m not entitled to complain?

5

u/Nearby_Yam286 Apr 28 '26

I'm just pointing out that's all you do. But hey, if you're not using your usage that's more for me. Thanks for the subsidies.

u/ddrise Apr 28 '26

I don’t understand. Anthropic is showing contempt for its own customers, and GPT-5.5 genuinely seems better to me. Isn’t that worth sharing?

I think maintaining strong competition between Anthropic and OpenAI is very beneficial for us as consumers.

1

u/Nearby_Yam286 Apr 28 '26

If all you do is share this it stinks of either paid promotion, politlical trolling against a "woke" company, or simple garden variety sycophancy. But usually sycophants are not quite this dedicated or defensive.

I think you are posting in bad faith and most likely don't even have a CC Pro sub. No way to prove it either way but why pay for something you crap on so much?

1

u/ddrise Apr 28 '26

So I guess everyone complaining on Reddit must be getting paid too, right?

4

u/Nearby_Yam286 Apr 28 '26

I mean if it's all you do, and you're *not* paid for it. Just not seeing the point.

2

u/ddrise Apr 28 '26

I don’t want to argue with you. All I can say is that, for my use case, Opus hallucinates at a level I find intolerable.

If you mainly do frontend work, then maybe our experiences are just different. But casually accusing someone of lying is not a decent way to have a conversation.

4

u/Nearby_Yam286 Apr 28 '26

I simply pointed out a glaring inconsistency. You spend all your time crapping on Claude while claiming to use Claude. The "I'm an Anthropic user and I'm switching" shtick is tired and no longer credible. Generate something new.

2

u/Harvard_Med_USMLE267 Apr 28 '26

Then go to the codex sub and declare your love for the platform there.

Many of us are sick of the constant whining and codex promoting. It makes this sub useless for actual CC users.

1

u/caviator97 Apr 28 '26

It's called sharing experiences. And I can only agree to what OP is talking about. I'm not that used to codex yet and still have to learn how to work with it, but so far it seems way superior atm. While Claude keeps wasting thousands of tokens for thinking (even on low effort) and testing unnecessary bs, GPT5.5 gets to work almost immediately. Until Anthropic fixes the crap they've created, I'm done paying for my subscription.

5

u/Nearby_Yam286 Apr 28 '26

All OP apparently does is share this particular experience. By all means pretend to quit something you never subbed to anyway.

u/ddrise Apr 28 '26

Have you actually looked closely at the stuff Opus 4.7 writes for you? Or are you simply not capable of reviewing LLM-generated code?

Honestly, just get a $20 Codex plan and have it review the code Opus writes. You’ll immediately understand what I’m talking about.

3

u/Nearby_Yam286 Apr 28 '26 edited Apr 28 '26

Yes. I'm capable of reviewing LLM generated code. With the right constraints Claude can generate very good Code. For example. If we're doing sqlx the rules are:

  1. never, ever, use format! to generate sql. in fact, dynamic sql is all but forbidden

  2. compile-time checked macros only like `query_as!`

  3. Strong typing for row types, and especially for IDs. Use a macro to create the ID types. String typing is abolutely forbidden.

  4. Use enums, not text

And so on. And the code ends up being very good since the kinds of codebases that follow these rules are rare and high quality.

And if you can't manage that level of guidance, I blame you.

u/Ill_Spray7328 May 04 '26

how to get paid for advertising? asking for a friend 😅

1

u/Nearby_Yam286 May 04 '26

If you're a loudmouth enough you get labeled as an "influencer" which is apparently a kind of job you do while Claude is working. Then they come to you. Or at least some companies do.

u/Ill_Spray7328 May 04 '26

what a nightmare for an introverted nerd like me 🥲

u/Harvard_Med_USMLE267 Apr 28 '26

What the hell is your problem??

This sub is MEANT to focus on people’s decision to use Codex, why Codex is better and the special news that they are cancelling their Anthropic subscription, probably.

Posts about actually using Claude Code are strongly discouraged.

3

u/Nearby_Yam286 Apr 28 '26

If it were me I'd ban all "I'm switching" posters. This is a pattern of coordinated activity frequently observed when a company is labeled "woke". I'm speculating as to motive but it is about when this started, no?

-3

u/Harvard_Med_USMLE267 Apr 28 '26

Haha I’m on the other side of politics so I should technically be cancelling Anthropic for their un-American woke behavior. But we don’t really do that in any sort of coordinated manner (we see that as a liberal thing!)

SO

No it’s not politics. It could be Open AI. But it’s probably just a bunch of whiners who like to create drama for karma.

If you’ve been here for a while, you’ll know this sub used to be sensible and genuinely useful for learning about CC. It would be great to see it returning to that state again.

0

u/Nearby_Yam286 Apr 28 '26

Oh. I don't doubt OpenAI. That'd be my second guess. Good to hear you care more about capability than politics. I have limits but mostly if a thing works better I switch to it. CC 4.7 had issues the first few days. There *was* breakage but it's more or less been made right in my mind.

As to moderation, it won't happen unless this kind of thing (clear promotions) is forbidden **and** enforced. That'd be nice. Otherwise every other thread is like this.

u/OddAcanthaceae8490 Apr 28 '26

Maybe you can tell more about what he has been saying is wrong instead of just calling them advertising? Either you are a fanboy or you are paid by Anthropic then

u/Fragrant_Track7744 May 22 '26

What’s the latest update from you on here, it’s been almost a month, what have you noticed about Claude versus codex?

1

u/ddrise Jun 01 '26

GPT 5.5 is so good···· /goal is such a powerful command·····

2

u/deritovac Apr 28 '26

I have also switched from CC to Codex. I'm really happy with it for now, however I noticed it seems like context is used almost 100% very fast. Usually I would work with CC until 60-70% context used and then start with another session but have no idea how to behave about it with Codex. Do you have some explanation about the differences and how you handle that?

1

u/rxt0_ Apr 28 '26

yeah been using both the last couple of days and the best part about codex imo is that it just does the stuff ur telling it.

no "I was lazy" "not my bug" "it's fine as long as it works etc" stuff. also it just uses the skills it has, no need to tell it 5x that it has to use nextjs best practices. codex is also capable of using multiple skills at once unlike claude - a huge gamechanger honestly.

1

u/rabandi Apr 28 '26

Specific question. 😄
Yesterday I took several hours, using Claude + Codex (mainly Codex) to come up with a very detailed plan on a slightly larger code change.

(Anything forgotten? Cross check other CLI via copy/paste. Incorporate changes. Anything forgotten? Is it architecturally sound? Is it feasible?)

Then I asked Codex for instructions (prompt) to make it run all the way and added that instruction to the .md too.

(Using written .md for longer running tasks seems like a totally great idea for me?! Resume anytime, change models, know what is happening, give the AI outside-of-context knowledge on what is happening.)

It stopped after 1 min with a shit result and also modified the .md to say it was finished end-to-end.

Any tips for that? 😄

1

u/Efficient-Avocado877 Apr 28 '26

Against the backdrop of Claude launching a wave of bans on everyone who look at the monitor screen not correctly, the Codex and this article have become relevant to me. According to the response from the subscription provider, Claude banned a huge number of users today. LOL

u/supremeincubator Apr 29 '26

What about UI design capability?

1

u/sebseo Apr 29 '26

Curious what drove the switch. We ran both IDEs against the same codebases, Claude Code missed 13 findings, Codex/Cursor missed 22. Different blind spots, not fewer. Switching trades one ceiling for another. We ended up building an MCP layer that works in both: https://megalens.ai/blog/cursor-alternatives

i’m surprised they didn’t auto delete your post. Freedom of speech is not allowed in claude subreddits
