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, not less than evaluating the mannequin Claude Opus 4.8 and Codex with GPT-5.5.
Nevertheless, they positively 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 during which situations I make the most of every of them.
You will need to 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 arising, corresponding to Google with their Gemini fashions.
Why use Claude Code and Codex
To start with, the rationale you ought to be utilizing Claude Code and Codex is that they’re extremely highly effective coding brokers. They will, after all, be used to finish programming duties, however they will also be used to finish basically another workplace or computer-related duties that you just may work on.
For instance, in order for you:
- Arrange a finances
- Create a PowerPoint
- Draft an electronic mail
Or another such activity, I attempt to apply coding brokers to basically all duties that I do, as an alternative of manually performing duties myself on the pc. I attempt to make a coding agent full the duty. This may, for instance, be establishing a brand new framework in your software as an alternative of studying by means of the API and establishing all the pieces within the UI. I as an alternative fetch an API key and provides it to my coding agent, and make the coding agent arrange all the pieces for me.
How I apply Claude Code and Codex
Now, on this part, I’ll talk about how I apply Claude Code and Codex, during which conditions I exploit 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 recently that provides me extremely good outcomes and helps the fashions construct very strong code.
Situations during which I favor Claude Code
Firstly, I need to cowl the situations during which I favor Claude Code. I’d say my major coding agent driver once I’m interacting with the code myself is Claude Code. It’s the primary go-to software I exploit when making or writing code to resolve issues on my pc.
It’s because Claude Code could be very strong. It’s superb at planning, asking me the correct inquiries to make clear ambiguities, and making me conscious of any huge selections that I have to make that can influence the answer the agent is constructing.
I additionally discover that Claude Code has numerous options that I actually admire 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 on the subject of the options of their CLI software, which makes me favor Claude Code typically.
These are options corresponding to:
- Recap – Claude Code offers a recap on the backside of the chat, which makes it actually easy to choose up code and textual content once more should you’ve been away from a Claude Code tab.
- Create worktrees on startup. In Claude Code, you may kind -w, which is able to routinely create a worktree for the repository you’re working in. This isn’t at present attainable in Codex.
- Workflows – Claude Code not too long ago launched a really highly effective function referred to as Workflows, which lets you spend much more tokens to finish extra complicated duties. I discover this very priceless 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 very best options first. In some situations, Codex implements these options at a later level.
Total, I believe Claude Code works effectively as the primary driver on your coding brokers. Most duties that you just need to do might be accomplished by Claude Code, which can be why I selected to have a Claude Code subscription. Moreover, I additionally preferred the UI within the Claude software for desktop, and I believe Claude Cowork is an excellent function. After all, OpenAI has an identical app, however I don’t suppose it’s pretty much as good and as well-designed.
If you’re a non-technical consumer, I’d positively suggest utilizing the Claude software.
Situations during which I favor Codex
Although Claude Code is extremely highly effective as my major driver, there are numerous use instances I exploit Codex for. To start with, I after all use Codex every time Claude Code is down, which has occurred a stunning variety of instances recently. You possibly can see how typically this has occurred on the Claude Standing web 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 priceless in different conditions, like:
- Performing code evaluations
- Powering OpenClaw bots
- Getting work performed sooner (quick mode)
The three factors talked about above are my three major causes for selecting Codex once I do.
Firstly, I believe Codex performs glorious code evaluations, they usually’ve made a quite simple setup so that you can carry out code evaluations with Codex. You possibly can merely set up it into your GitHub and tag it to carry out a code evaluation.
Secondly, I believe Codex might be the very best different you’ve got for powering your OpenClaw bots. The reason being that you could energy your OpenClaw bots by means of a Codex subscription, which you can not do with Claude Code anymore. I consider that that is mainly the 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 alone 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 gives one thing referred to as quick mode, which makes the coding agent sooner with out sacrificing high quality in any respect. That is an choice you may have the place the agent will probably 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 total an excellent different.
I additionally consider OpenAI’s Codex is extra environment friendly at fixing numerous duties, even should you don’t use quick mode. Lastly, I additionally suppose 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 need to carry out, and I hardly ever encounter this subject with OpenAI’s Codex.
Combining Claude Code and Codex
Lastly, I additionally need 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 evaluation the code that Claude has made. In lots of instances, 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 difficulty. I then make Claude Code routinely repair the difficulty from Codex and re-request evaluation. Have them iterate collectively like that till the evaluation from OpenAI’s Codex goes by means of as all good.
It is a quite simple setup, as you may merely immediate Claude Code to behave on this manner 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 delivered to manufacturing if it weren’t for both Codex performing the evaluation or having a human evaluation. Nevertheless, having human evaluations now could be, after all, not attainable anymore, given the quantity of code we’re producing.
I consider combining OpenAI’s Codex with Claude Code is a option to write even higher code and get the very best out of each the coding brokers and much more. I consider combining these two fashions offers worth that goes above the sum of its components.
Conclusion
On this article, I’ve mentioned mix Claude Code and OpenAI’s Codex for optimum coding effectivity and energy. I mentioned why you ought to be utilizing Claude Code and Codex, which is clearly to save lots of time and carry out work extra effectively. I then mentioned during which situations I favor Claude Code and during which situations I favor OpenAI’s Codex. They positively have strengths in several areas, which is nice in case you are a consumer of each platforms, as you may select to make use of a platform that works greatest for any given activity. Lastly, I additionally coated a really highly effective approach the place I mix each Claude Code and Codex to put in writing extremely strong code and uncover points earlier than they arrive to manufacturing. I consider you, as a developer, ought to positively be paying shut consideration to the coding agent area and attempting 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.
