These releases are lacking something. Yes, they optimised for benchmarks, but it’s just not all that impressive anymore. It is time for a product, not for a marginally improved model.

The model was released less than an hour ago, and somehow you've been able to form such a strong opinion about it. Impressive!

If you don't want to click in, easy comparison with other 2 frontier models - https://x.com/OpenAI/status/2029620619743219811?s=20

It seems that all frontier models are basically roughly even at this point. One may be slightly better for certain things but in general I think we are approaching a real level playing field field in terms of ability.

That has been true for some time now, definitely since Claude 3 release two years ago.

5.3 codex was a huge leap over 5.2 for agentic work in practice. have you been using both of those or paying attention more to benchmark news and chatgpt experience?

Earlier quoted context omitted.

I haven't tried the $200 plans by I have Claude and Codex $20 and I feel like I get a lot more out of Codex before hitting the limits. My tracker certainly shows higher tokens for Codex. I've seen others say the same.

Sadly comment ratings are not visible on HN, so the only way to corroborate is to write it explicitly: Codex $20 includes significantly more work done and is subjectively smarter.

Agree. Claude tends to produce better design, but from a system understanding and architecture perspective Codex is the far better model

Bit concerning that we see in some cases significantly worse results when enabling thinking. Especially for Math, but also in the browser agent benchmark. Not sure if this is more concerning for the test time compute paradigm or the underlying model itself. Maybe I'm misunderstanding something though? I'm assuming 5.4 and 5.4 Thinking are the same underlying model and that's not just marketing.

The thinking models are additionally trained with reinforcement learning to produce chain of thought reasoning

5.4 vs 5.3-Codex? Which one is better for coding?

Literally just released, I don't think anyone knows yet. Don't listen to people's confident takes until after a week or two when people actually been able to try it, otherwise you'll just get sucked up in bears/bulls misdirected "I'm first with an opinion".
