and Codex are extremely highly effective coding brokers by themselves. I’ve extensively tried each fashions, and for my part, they’re each superb and comparable, no less than evaluating the mannequin Claude Opus 4.8 and Codex with GPT-5.5.
Nevertheless, they undoubtedly have totally different strengths and weaknesses. In some situations, I discover myself utilizing Claude, and in different situations, I discover myself utilizing Codex. On this article, I’ll talk about how I mix the 2 fashions and through which situations I make the most of every of them.
It is very important word that the panorama of coding brokers is shifting extremely rapidly. You may see that both Claude Code or Codex is shifting forward of the opposite within the coming months, or perhaps a third competitor developing, comparable to Google with their Gemini fashions.
Why use Claude Code and Codex
Initially, the rationale you need to be utilizing Claude Code and Codex is that they’re extremely highly effective coding brokers. They’ll, in fact, be used to finish programming duties, however they will also be used to finish basically another workplace or computer-related duties that you simply may work on.
For instance, in order for you:
- Arrange a price range
- Create a PowerPoint
- Draft an e mail
Or another such process, I attempt to apply coding brokers to basically all duties that I do, as a substitute of manually performing duties myself on the pc. I attempt to make a coding agent full the duty. This could, for instance, be organising a brand new framework in your utility as a substitute of studying by the API and organising every thing within the UI. I as a substitute fetch an API key and provides it to my coding agent, and make the coding agent arrange every thing for me.
How I apply Claude Code and Codex
Now, on this part, I’ll talk about how I apply Claude Code and Codex, through which conditions I take advantage of which, and what the totally different strengths and weaknesses are. Lastly, I’ll cowl a particularly highly effective approach that I’ve began actively utilizing currently that provides me extremely good outcomes and helps the fashions construct very sturdy code.
Situations through which I favor Claude Code
Firstly, I wish to cowl the situations through which I favor Claude Code. I’d say my important coding agent driver after I’m interacting with the code myself is Claude Code. It’s the primary go-to software I take advantage of when making or writing code to unravel issues on my pc.
It is because Claude Code may be very sturdy. It’s superb at planning, asking me the correct inquiries to make clear ambiguities, and making me conscious of any massive selections that I have to make that may influence the answer the agent is constructing.
I additionally discover that Claude Code has a whole lot of options that I actually respect and typically miss from Codex. Total, they’re not even that superior options, however I simply discover that Claude Code is continually forward of Codex in terms of the options of their CLI software, which makes me favor Claude Code typically.
These are options comparable to:
- Recap – Claude Code gives a recap on the backside of the chat, which makes it actually easy to select up code and textual content once more in the event you’ve been away from a Claude Code tab.
- Create worktrees on startup. In Claude Code, you may sort -w, which can mechanically create a worktree for the repository you’re working in. This isn’t at present potential in Codex.
- Workflows – Claude Code just lately launched a really highly effective characteristic known as Workflows, which lets you spend much more tokens to finish extra advanced duties. I discover this very precious to finish migrations, for instance.
I’ve additionally skilled that Claude Code had some options some time in the past that Codex has now picked up on. Nevertheless, I believe it’s a really normal word I’d make that Claude Code is forward on the options and often publishes the most effective options first. In some situations, Codex implements these options at a later level.
Total, I believe Claude Code works properly as the primary driver to your coding brokers. Most duties that you simply wish to do may be accomplished by Claude Code, which can also be why I selected to have a Claude Code subscription. Moreover, I additionally preferred the UI within the Claude utility for desktop, and I believe Claude Cowork is an excellent characteristic. In fact, OpenAI has an identical app, however I don’t assume it’s pretty much as good and as well-designed.
In case you are a non-technical consumer, I’d undoubtedly suggest utilizing the Claude utility.
Situations through which I favor Codex
Despite the fact that Claude Code is extremely highly effective as my important driver, there are a whole lot of use circumstances I take advantage of Codex for. Initially, I in fact use Codex each time Claude Code is down, which has occurred a shocking variety of occasions currently. You may see how typically this has occurred on the Claude Status page. We see that the Claude Code uptime is approaching 99.0%, which I’d regard as fairly poor efficiency.
Nevertheless, Codex isn’t simply good as a secondary different to Claude Code. It’s additionally extremely precious in different conditions, like:
- Performing code evaluations
- Powering OpenClaw bots
- Getting work completed sooner (quick mode)
The three factors talked about above are my three important causes for selecting Codex after I do.
Firstly, I believe Codex performs wonderful code evaluations, and so they’ve made a quite simple setup so that you can carry out code evaluations with Codex. You may merely set up it into your GitHub and tag it to carry out a code evaluate.
Secondly, I believe Codex might be the most effective different you’ve got for powering your OpenClaw bots. The reason being which you could energy your OpenClaw bots by a Codex subscription, which you can’t do with Claude Code anymore. I imagine that that is principally the very best intelligence you may get, contemplating Codex is a frontier LLM. It’s on a subscription foundation, which makes it fairly low-cost to run OpenClaw bots like this. I can each run Codex as a programming or coding agent by myself pc and have it energy a number of OpenClaw bots with out hitting limits.
OpenAI limits are actually beneficiant, as I discussed in my final paragraph. Moreover, OpenAI additionally presents one thing known as quick mode, which makes the coding agent sooner with out sacrificing high quality in any respect. That is an possibility you may have the place the agent shall be round 50% sooner, and also you’ll spend about twice as a lot of your token restrict. Nevertheless, I discover that I’m hardly ever hitting the OpenAI token limits, so utilizing quick mode is general a fantastic different.
I additionally imagine OpenAI’s Codex is extra environment friendly at fixing a whole lot of duties, even in the event you don’t use quick mode. Lastly, I additionally assume Codex is considerably higher at following pure directions from the consumer. I do discover that Claude Code, in some situations, performs work I don’t wish to carry out, and I hardly ever encounter this challenge with OpenAI’s Codex.
Combining Claude Code and Codex
Lastly, I additionally wish to cowl a small part on combining Claude Code and Codex into the identical coding session. One very highly effective approach I’ve developed and located that works rather well:
I make Claude Code carry out my preliminary planning and code execution to implement the answer. I then make my Claude Code tag OpenAI’s Codex in a PR to evaluate the code that Claude has made. In lots of circumstances, I discover that Codex is ready to uncover points that Claude wasn’t conscious of, however that Claude Code agrees with after Codex’s presentation of the problem. I then make Claude Code mechanically repair the problem from Codex and re-request evaluate. Have them iterate collectively like that till the evaluate from OpenAI’s Codex goes by as all good.
It is a quite simple setup, as you may merely immediate Claude Code to behave on this method after you’ve put in OpenAI’s Codex into your repository. This has uncovered a lot of bugs for me that Claude Code launched when it wrote the code, and it could have been dropped at manufacturing if it weren’t for both Codex performing the evaluate or having a human evaluate. Nevertheless, having human evaluations now’s, in fact, not potential anymore, given the quantity of code we’re producing.
I imagine combining OpenAI’s Codex with Claude Code is a method to write even higher code and get the most effective out of each the coding brokers and much more. I imagine combining these two fashions gives worth that goes above the sum of its components.
Conclusion
On this article, I’ve mentioned how one can mix Claude Code and OpenAI’s Codex for max coding effectivity and energy. I mentioned why you need to be utilizing Claude Code and Codex, which is clearly to save lots of time and carry out work extra effectively. I then mentioned through which situations I favor Claude Code and through which situations I favor OpenAI’s Codex. They undoubtedly have strengths in several areas, which is nice if you’re a consumer of each platforms, as you may select to make use of a platform that works greatest for any given process. Lastly, I additionally coated a really highly effective approach the place I mix each Claude Code and Codex to write down extremely sturdy code and uncover points earlier than they arrive to manufacturing. I imagine you, as a developer, ought to undoubtedly be paying shut consideration to the coding agent area and making an attempt out any new fashions that come out, such because the Claude Opus 4.8 mannequin that was launched just a few days in the past.
