Thank you for coming on HN and offering to answer questions.[a]
This is a fantastic piece, very timely, evidently well-researched, and also well-written. Judging by the little that I know, it's accurate. Thank you for doing the work and sharing it with the world.
OpenAI may be in a more tenuous competitive position than many people realize. Recent anecdotal evidence suggests the company has lost its lead in the AI race to Anthropic.[b]
Many people here, on HN, who develop software prefer Claude, because they think it's a better product.[c]
Is your understanding of OpenAI's current competitive position similar?

Thank you for this, very much appreciate the thoughtful response.
The piece captures some of the anxieties within OpenAI right now about their competitive position. This obviously ebbs and flows but of late there has been much focus on Anthropic's relative position. We of course mention the allegations of "circular deals" and concerns about partners taking on debt.
Thank you. Yes, I saw that. The company's always been surrounded by endless talk about insane hype, speculative bubbles, and financial engineering. I wasn't asking so much about that.
I was asking more about your informed view on how OpenAI's technology, products, and roadmap are perceived, particularly by customers and partners, in comparison to those of competitors.
If you have an opinion about that, everyone here would love to hear about it.
at this point even googles ai search results are better than gpt - obv. this is not for full programs but if you know what youre doing and just want a snippet, thats all you need.
Wild how different experience people can have. Both Google's models and Anthrophic's hallucinate a lot for me, even when I try the expensive plans and with web searches, for some reason, and none of them come close to the accuracy and hallucination-free responses of ChatGPT Pro, which to me still is SOTA and has been since it was made available. But people keep having opposite experiences apparently, I just can't make sense of it.
Ronan Farrow's expertise is investigations into elite amorality, not evaluating technical products. Why are you asking this question?
I didn't asking him to evaluate them. I asked him how customer and partners perceive them.
He's had so many conversations that he likely has a sense of how perceptions of the company and its offerings have changed.
I'm curious.
Much of the article and general palace intrigue is predicated on the idea that OpenAI has a singularly revolutionary product. If it later turns out to be a commodity, or OpenAI is simply outcompeted nonetheless, then the idea that Sam Altman's personal shortcomings are something to stress about would seem quaint. Just another hubristic tech billionaire acting in bad faith doesn't really pry attention the same way as someone "controlling your future".
My guess is that the answer to your question, fantastic question, is that nobody knows. I remember having the same thoughts when Covid was first “arriving” if you will: we wanted people in the know to throw us a nugget of information, and they just didn’t know.
As it turns out, and what I’m kind of going with for this LLM shit, is that it’ll play out exactly how you think it will. The companies are all too big to fail, with billionaire backers who would rather commit fraud than lose money.
How would fraud help here? Don't they just need scale of lots of customers paying a little bit? How do you fraud your way into that?
If you were in charge of the deciding what should be done with Sam Altman, what would you choose?
Many of us prefer OpenAI's Codex, because we think it's a better product.
No comment on the CEO: I just find the product superior in everything but UI/UX and conversation. It's better at quality code.
Usage limits are more generous and GPT 5.4 is a good model, but yes, UI/UX lags behind Claude Code. Currently I'm especially missing /rewind with code restoration and proper support for plugin marketplaces
Who is “us”? It does seem that some scientists prefer Codex for its math capabilities but when it comes to general frontend and backend construction, Claude Code is just as good and possibly made better with its extensive Skills library.
Both codex and Claude code fail when it comes to extremely sophisticated programming for distributed systems
As a scientist (computational physicist, so plenty of math, but also plenty of code, from Python PoCs to explicit SIMD and GPU code, mostly various subsets of C/C++), I can confirm - Codex is qualitatively better for my usecases than Claude. I keep retesting them (not on benchmarks, I simply use both in parallel for my work and see what happens) after every version update and ever since 5.2 Codex seems further and further ahead. The token limits are also far more generous (and it matters, I found it fairly easy to hit the 5h limit on max tier Claude), but mostly it's about quality - the probability that the model will give me something useful I can iterate on as opposed to discard immediately is much higher with Codex.
For the few times I've used both models side by side on more typical tasks (not so much web stuff, which I don't do much of, but more conventional Python scripts, CLI utilities in C, some OpenGL), they seem much more evenly matched. I haven't found a case where Claude would be markedly superior since Codex 5.2 came out, but I'm sure there are plenty. In my view, benchmarks are completely irrelevant at this point, just use models side by side on representative bits of your real work and stick with what works best for you. My software engineer friends often react with disbelief when I say I much prefer Codex, but in my experience it is not a close comparison.
I've tried both against similar and haven't found it such a clear cut difference. I still find neither are able to fully implement a complex algorithm I worked on in the past correctly with the same inputs. Not sharing exactly the benchmark I'm using but think about something for improving performance of N^2 operations that are common in physics and you can probably guess the train of thought.
>As a scientist (computational physicist,
Is there one that you prefer for, i dunno, physics?
I'm in that camp -- I have the max-tier subscription to pretty much all the services, and for now Codex seems to win. Primarily because 1) long horizon development tasks are much more reliable with codex, and 2) OpenAI is far more generous with the token limits.
Gemini seems to be the worst of the three, and some open-weight models are not too bad (like Kimi k2.5). Cursor is still pretty good, and copilot just really really sucks.
Claude Code, Codex, and Cursor are old news. If you're having problems, it's because you're not using the latest hotness: Cludge. Everyone is using it now - don't get left behind.
Cludge has been left behind by Clanker, that’s the new hotness. 45B valuation!
Us = me and say /r/codex or wherever Codex users are. I've tried both, liked both, but in my projects one clearly produces better results, more maintainable code and does a better job of debugging and refactoring.
That's interesting, I actively use both and usually find it to be a toss up which one performs better at a given task. I generally find Claude to be better with complex tool calls and Codex to be better at reviewing code, but otherwise don't see a significant difference.
If you want to find an advocate for Codex that can give a pretty good answer as to why they think it's better, go ask Eric Provencher. He develops https://repoprompt.com/. He spends a lot of time thinking in this space and prefers Codex over Claude, though I haven't checked recently to see if he still has that opinion. He's pretty reachable on Discord if you poke around a bit.
Quite irrelevant what factions think. This or that model may be superior for these and those use cases today, and things will flip next week.
Also. RLHF mean that models spit out according to certain human preference, so it depends what set of humans and in what mood they've been when providing the feedback.
Any difference in performance on mobile development?
For that I'm not so sure. I tried both early 2025 and was disappointed in their ability to deal with a TCA based app (iOS) and Jetpack compose stuff on Android, but I assume Opus 4.6 and GPT 5.4 are much better.
yea Im not in this "us" you speak of.
Of course you're not one of "us" if you're one of "them".
As some other people mentioned, using both/multiple is the way to go if it's within your means.
I've been working on a wide range of relatively projects and I find that the latest GPT-5.2+ models seem to be generally better coders than Opus 4.6, however the latter tends to be better at big picture thinking, structuring, and communicating so I tend to iterate through Opus 4.6 max -> GPT-5.2 xhigh -> GPT-5.3-Codex xhigh -> GPT-5.4 xhigh. I've found GPT-5.3-Codex is the most detail oriented, but not necessarily the best coder. One interesting thing is for my high-stakes project, I have one coder lane but use all the models do independent review and they tend to catch different subsets of implementation bugs. I also notice huge behavioral changes based on changing AGENTS.md.
In terms of the apps, while Claude Code was ahead for a long while, I'd say Codex has largely caught up in terms of ergonomics, and in some things, like the way it let's you inline or append steering, I like it better now (or where it's far, far, ahead - the compaction is night and day better in Codex).
(These observations are based on about 10-20B/mo combined cached tokens, human-in-the-loop, so heavy usage and most code I no longer eyeball, but not dark factory/slop cannon levels. I haven't found (or built) a multi-agent control plane I really like yet.)
Codex won me over with one simple thing. Reliability. It crashed less, had less load shedding and its configuration is well designed.
I do regular evaluation of both codex and Claude (though not to statistical significance) and I’m of the opinion there is more in group variance on outcome performance than between them.
This is the way. Eg. IME Gemini is really damn good at sql.
I've found claude startlingly good at debugging race conditions and other multithreading issues though.
My rule of thumb is that its good for anything "broad", and weaker for anything "deep". Broad tasks are tasks which require working knowledge of lots of random stuff. Its bad at deep work - like implementing a complex, novel algorithm.
LLMs aren't able to achieve 100% correctness of every line of code. But luckily, 100% correctness is not required for debugging. So its better at that sort of thing. Its also (comparatively) good at reading lots and lots of code. Better than I am - I get bogged down in details and I exhaust quickly.
An example of broad work is something like: "Compile this C# code to webassembly, then run it from this go program. Write a set of benchmarks of the result, and compare it to the C# code running natively, and this python implementation. Make a chart of the data add it to this latex code." Each of the steps is simple if you have expertise in the languages and tools. But a lot of work otherwise. But for me to do that, I'd need to figure out C# webassembly compilation and go wasm libraries. I'd need to find a good charting library. And so on.
I think its decent at debugging because debugging requires reading a lot of code. And there's lots of weird tools and approaches you can use to debug something. And its not mission critical that every approach works. Debugging plays to the strengths of LLMs.
Not a scientist and use codex for anything complex.
I enjoy using CC more and use it for non coding tasks primarily, but for anything complex (honestly most of what I do is not that complex), I feel like I am trading future toil for a dopamine hit.
I’m one of those ‘us’, Claude’s outputs require significant review and iteration effort (to put it bluntly they get destroyed by gpt and Gemini). I’m basically using sonnet to do code search and write up since it is a better (more human-like) writer than gpt and faster and more reliable than gemini, but that’s about it.
Many paying customers say that Anthropic degraded the capability of Opus and Claude Code in the last months and the outcomes are worse. There are even discussions on HN about this.
Last one is from yesterday: https://news.ycombinator.com/item?id=47660925
I also find Codex much more generous in terms of what you get with a Pro ($20/mo) subscription. I use it pretty much non-stop and I have yet to hit a limit. Weekly reset is much better as well.
GPT/claude/gemini is pretty interchangeable at this point.
Absolutely not the case. They're complementary.
i find myself being more productive with codex/copilot on coding tasks, but claude does seem to be better at planning
I prefer GLM 5.1 and MiniMax 2.7. With a better harness like Forge Code, I have better results for way less money than by using GPT and Opus.
Does this work for people? To me having a "better product" would be completely irrelevant if the use cases are evil.

Here is the actual link, not a link to some weird third-party site that can't be trusted.

FYI xcancel is just a mirror that allows reading replies without needing an account.
Whereas X can be trusted?
Yes? It's the data source, not a third-party. How is this even a question?
There's pedantic, and then there's needlessly pedantic.
xcancel is a valid workaround for X links on Hacker News and is sufficient for original attribution.
X restricts what you can view without logging in. Many folks don't want to log in to X, for obvious reasons. Posting an xcancel link is kinda like folks posting various `archive` URLs to bypass paywalls, work around overloaded servers, etc. That's an extremely common practice here that usually goes without comment.
It's worth noting Codex has 2x more stories than Claude https://hn.algolia.com/?query=codex
But by page 5, those stories have around 50-60 karma, while claude page five is still 500+
(i found your comment surprising based on my daily hn reading recollection - i mostly read top N daily and feel i only occassionally see codex stories).
Yeah we moved to Claude a few months ago, mostly because the devs kept using it anyway. Altman stuff is interesting but at the end of the day you just go with whatever tool works
> You may want to provide proof online that you are who you say you are
Unfortunately it probably doesn't even matter here on HN considering how brigaded down this story is predictably getting.
But yeah, it was a fantastic piece.
It wasn't getting "brigaded down" - it set off a software penalty called the flamewar detector. I turned that off as soon as I saw it.
Thank you for keeping HN sane :-)
