Every new model is ‘state-of-the-art’. This term is getting annoying.

#242> new context management using compaction.
Nice! This was one of the more "manual" LLM management things to remember to regularly do, if I wanted to avoid it losing important context over long conversations. If this works well, this would be a significant step up in usability for me.

#243I've benchmarked it on the Extended NYT Connections benchmark ( https://github.com/lechmazur/nyt-connections/ ): The high-reasoning version of GPT-5.2 improves on GPT-5.1: 69.9 → 77.9. The medium-reasoning version also improves: 62.7 → 72.1. The no-reasoning version also improves: 22.1 → 27.5. Gemini 3 Pro and Grok 4.1 Fast Reasoning still score higher.
Gemini 3 Pro Preview gets 96.8% on the same benchmark? That's impressive

Not sure what you mean, Altman does that fake-humility thing all the time. It's a marketing trick; show honesty in areas that don't have much business impact so the public will trust you when you stretch the truth in areas that do (AGI cough ).
I'm confident that GP is good faithed though. Maybe I am falling for it. Who knows? It doesn't really matter, I just wanted to be nice to the guy. It takes some balls posting as OpenAi employee here, and I wish we heard from them more often, as I am pretty sure all of them lurk around.
It's the only reasonable choice you can make. As an employee with stock options you do not want to get trashed on Hackernews because this affects your income directly if you try to conduct a secondary share sale or plan to hold until IPO.
Once the IPO is done, and the lockup period is expired, then a lot of employees are planning to sell their shares. But until that, even if the product is behind competitors there is no way you can admit it without putting your money at risk.

#245Earlier quoted context omitted.
Because their main competition (Google and Anthropic) have caught up and even started to surpass them, and comparisons would simply drive it home.
Why do they care so much? They're a non-profit dedicated to the betterment of humanity via open access to AI. They have nothing to hide. They have no motivation to lie, or lie by omission.

We're still talking about OpenAI right?
Re: GPT-5.2
#246For me the last remaining killer feature of ChatGPT is the quality of the voice chat. Do any of the competitors have something like that?
I'm a big user of Gemini voice. My sense is that Gemini voice uses very tight system prompts that are designed to give you an answer and kind of get you off the phone as much as possible. It doesn't have large context at all.
That's how I judge quality at least. The quality of the actual voice is roughly the same as ChatGPT, but I notice Gemini will try to match your pitch and tone and way of speaking.
Edit: But it looks like Gemini Voice has been replaced with voice transcription in the mobile app? That was sudden.

#247Is it me, or did it still get at least three placements of components (RAM and PCIe slots, plus it's DisplayPort and not HDMI) in the motherboard image[0] completely wrong? Why would they use that as a promotional image? 0: https://images.ctfassets.net/kftzwdyauwt9/6lyujQxhZDnOMruN3f...
Yep, the point we wanted to make here is that GPT-5.2's vision is better, not perfect. Cherrypicking a perfect output would actually mislead readers, and that wasn't our intent.
But it’s completely wrong.

#248> Unlike the previous GPT-5.1 model, GPT-5.2 has new features for managing what the model "knows" and "remembers to improve accuracy. Dumb nit, but why not put your own press release through your model to prevent basic things like missing quote marks? Reminds me of that time an OAI released wildly inaccurate copy/pasted bar charts.
Humans are now expected to parse sloppy typing without complaining about it, just like LLMs do. Slop is the new normal.
Re: GPT-5.2
#249Feels a bit rushed. They haven’t even updated their API playground yet, if I select 5.2-chat-latest, I get:
Unsupported parameter: 'top_p' is not supported with this model.
Also, without access to the Internet, it does not seem to know things up to August 2025. A simple test is to ask it about .NET 10 which was already in preview at that time and had lots of public content about its new features.
The model just guessed and waved its hand about, like a student that hadn’t read the assigned book.

It may have been used, how could we know?
Mainly, I don't get why there are quote marks at all.
