Just remember an ethical programmer would never write a function “bombBagdad”. Rather they would write a function “bombCity(target City)”.

The marquee feature is obviously the 1M context window, compared to the ~200k other models support with maybe an extra cost for generations beyond >200k tokens. Per the pricing page, there is no additional cost for tokens beyond 200k: https://openai.com/api/pricing/ Also per pricing, GPT-5.4 ($2.50/M input, $15/M output) is much cheaper than Opus 4.6 ($5/M input, $25/M output) and Opus has a penalty for its beta >200…

Yeah, long context vs compaction is always an interesting tradeoff. More information isn't always better for LLMs, as each token adds distraction, cost, and latency. There's no single optimum for all use cases. For Codex, we're making 1M context experimentally available, but we're not making it the default experience for everyone, as from our testing we think that shorter context plus compaction works best for most p…

What needs to be an option is to allow complete and then compact and if needed go into the 1m version. That way you can get the most out of the shorter window but in the case where it just couldn't finish and compact in time it will (at cost) go over. I wonder how many tokens are actually left at the end of compaction on average. I know there have been many times where I likely needed just another 10-20k and a better stopping point would have been there.

So let me get this straight, OpenAi previously had an issue with LOTS of different models snd versions being available. Then they solved this by introducing GPT-5 which was more like a router that put all these models under the hood so you only had to prompt to GPT-5, and it would route to the best suitable model. This worked great I assume and made the ui for the user comprehensible. But now, they are starting to in…

Was this ever explicitly confirmed by OpenAI? I've only ever seen it in the form of a rumor.

I find it quite funny how this blog post has a big "Ask ChatGPT" box at the bottom. So you might think you could ask a question about the contents of the blog post, so you type the text "summarise this blog post". And it opens a new chat window with the link to the blog post followed by "summarise this blog post". Only to be told "I can't access external URLs directly, but if you can paste the relevant text or descri…

It looks like this doesn't work for users without accounts? It works when I'm logged in, but not logged out. I went ahead and reported it to the team. Thanks for letting us know!

Tell them to stop being evil while you're at it.

Genuinely curious, not being combative...what very interesting things have happened in the crypto space lately?

Oh, I dunno about lately (though I did stumble upon https://a16zcrypto.com/posts/article/big-ideas-things-excite... ) But when I was in the crypto space in 2018, there was a lot of interesting things happening in the smart contract world (like proofs of concepts of issuing NFTs as a digital "deed" to a physical asset like a house). I don't think any of those novel ideas went anywhere, but it was a fun time to be expe…

I have access to GPT-5.1 Pro at work, duuuuuuuuude, what a garbage. It is so slow and in many ocasions it does not work at all.

I wonder if 5.4 will be much if any different at all.

The question is still: Does it make your code better or worse? Only Opus makes it better, the rest worse. That's the treshold

5.2 to 5.3 is the big leap for coding agents, so I'd say you're already missing out quite a bit.

5.3 codex is a quite good coding agent for complex tasks.
