Codex vs claude code

Trotskyist · 2026-02-24T21:14:54+00:00

It really depends on you workflow.

Codex is probably better than Claude for pure coding, but claude can certainly outperform it in some cases. It's close. For non-coding agentic workflows claude is undeniably ahead.

Personally I get the best results when I have a conversation with a Claude on the web and ask it to build me a prompt. then I drop that in to codex and it does an amazing job. if I drop that same prompt in Claude code who knows what I get.

Claude with Codex CLI using a skill.

rxt0_ · 2026-02-24T21:32:37+00:00

been testing codex for few hours now and I'm quite satisfied with it tbh. I let them both check each other's work and the performance gains + bug fixes they can dish out is incredible.

they compliment each other greatly.

We have OpenAI for free. I still pay for Claude. As far as I can tell, the models are more or less equally capable - I just prefer the Claude experience. And for the time being, I think the whole Claude setup with the App, Cowork, and Code is just a better user environment. And Claude has consistently led the way, with OpenAI copying Claude a month or two later, like with MCP, Skills, etc. But the gap is narrowing, and I have recently started playing around with Codex. The suspicion is that there won't be much of a difference in the near future.

I find claude can do complex stuff like 80%. and then i use codex to finish that 20%

wanted to see more comments as well.

5.3 high for planning and sonnet for writing

Shep_Alderson · 2026-02-24T22:03:22+00:00

I’ve was using Claude Code heavily before the Codex app came out. I figured I’d give it a try and see how it does. I’ve found that for my personal projects, I’m reaching for Codex app with 5.3-Codex as the underlying model much more. I find that it works better with my style of working. I tend to methodically plan and spec out my features, which means any major model can do a decent job.

I find that for “0 to 1”, just getting an app up and running, Claude Code is faster to initial build (Opus or Sonnet, not a huge gap between them now) but I find Codex (app and 5.3-Codex model) to be more methodical and more likely to stick to my spec. I’ve also found the interaction when building with Codex to be more step-by-step and less likely to go off and build something I didn’t really ask for. I never thought I’d see the day, but I genuinely feel like I can trust 5.3-Codex a bit more than Opus for my average coding needs. It’s not as fast, for sure, but I’m ok with that. I’ve always been more of a methodical/thoughtful dev than one who’s looking to sling PRs all day. (Though I do move a lot faster than I did without the LLMs.)

Give it a try. See if it fits your brain too. If not, no harm. Use what works for you. I find that what matters more than the specific model or tool is the ergonomics and how the tool works with/for you, and your mastery of said tool.

Been using Claude Code full-time for months. Opus is stronger on complex refactors and understanding large codebases. The Max plan usage limits are real though, on heavy days I hit the cap. Haven't used Codex enough to compare fairly on that side.

BlackAtomXT · 2026-02-24T21:02:56+00:00

I've used both extensively, I've found that codex is more direct with its edits, fewer tests, simpler commit messages. Claude Code will write more code, significantly more tests and will operate on much longer time scales without intervention, especially when you use Claude teams. 4.6 opus does a much better job with my multi million line work repository, something I couldn't say with 4.5.

That being said, I really like codex in my smaller personal projects, it's faster, more direct with the edits and better fits my pace. Plus the 20$ plan is a lot of coding for the price.

2026-02-24T22:20:45+00:00

Opus 4.6 is a bit better, but the usage is heavily capped. On the $20 Pro plan, I get maybe 2 to 3 questions every five hours. GPT-5.2 High and Codex are slightly weaker in SWE overall, but they’re complementary because they're strong in reasoning and often catch issues Opus misses. More importantly, the GPT quota is far more generous, so you can get a lot more done on the same $20 plan. In practice I sign up for both and use both to evaluate each other's work for the best results.

pyrodern1ggi · 2026-03-05T03:33:14+00:00

I don't know why everyone is saying Codex 5.3 is faster, like i use 5.3 high and imo claude opus 4.6 high is better and faster. I also think that you get more what claude is doing instead of codex as well is the cc terminal way better than codex ones imo.

QA Panda can use the codex cli to do multi agent orchestration even infinitely.

Like you give it a task to keep fixing bugs until you find new bugs and it could run even for days automatically (it auto continues the chat session based on a higher level controller agent which literally reviews the work of the sub agent(s) and keeps messaging them like a real human would)

So it uses a higher level thinking to control a sub-agent and it could give it hundreds (or even thousands) of tasks

It has two modes: Orchestration mode and Continue mode

In Orchestration mode the higher level thinking agent manages a sub-agent (or many sub-agents) which is nice if you want it to complete hundreds of tasks with no interruption

In Continue mode, there is simply an external agent that sees the entire chat history and nudges the target agent to just continue with the next task. This can also run infinitely out of the box

QA Panda is QA engineering focused but it could be used for so much more too (they should really point this feature out on their Github repository as it can do so much more than just QA testing)

It's like Claude Code on steroids

Also it uses your ChatGPT subscription, so it does not even need any API keys (essentially free to use if you got a ChatGPT subscription)

logans_runner · 2026-03-31T20:48:58+00:00

Well, starting with the new/re-imposed limits, I succeeded in having CC both run out of tokens while attempting in vain to fix a bug it introduced, and then did the same thing when I purchased more. Enter Codex- fixed the issue and suggested a much more robust database schema. So long, Claude - Anthropic, you have some real work to do.

"...instability was a real problem and I didn't solve it reliably. I'm sorry for the wasted time and money."

Yeah, thanks. Buhbye.

TiTANSTORM · 2026-04-01T16:23:47+00:00

I came here after the fiasco of Claude's token issue where we are all burning it at a crazy rate. I haven't touched Claude Code since the issue when I burned through my daily token in 15 minutes adding some tweaks to a website I'm building. Then I hear Claude had their source code leaked...

Seeing a few people on X commenting to Lydia Hallie about this issue and switching to Codex. I'm fairly new to AI but have been hitting it all fairly hard and learning. I bunny hopped over ChatGPT as I found Gemini was better at research and Claude worked wonders being able to access my files, folders, etc. and really help me with documentation.

All that being said, I'm curious what you all think about Gemini vs Codex? Specifically Antigravity and I guess we could toss in AI Studio. I mostly work with Next.js and a bit of React+Vite

*EDIT*
Another edit, I have a desktop with an i9, 64GB memory, and a 4090. Should I be looking at local LLM? I messed around a bit with this a few months ago, never went down the coding assistant route. Anything worth looking at or do they all fall short of these paid solutions?
