The single biggest issue for me with ChatGPT right now is how absolutely awful it sounds in every answer. "Why it matters", "the big picture", "it's not jut you", the awful emphasis, the quotations with rhetorical questions, etc.. I don't know if it's intentional so you can easily spot ChatGPT-generated content on the web? The very first GPT-5 version was good but they ruined it immediately afterwards with "making the personality warmer" and making the same mistakes as 4o. I see now that they even ruined Japanese even though it was one of the best languages supported by ChatGPT (under "Limitations" at the end). I don't use it anymore, immensely disappointed.

I'm a bit confused by this branding (never even noticed that there was a 5.2-Instant), it's not a super fast 1000tok/s Cerebras based model which they have for codex-spark, it's just 5.2 w/out the router / "non-thinking" mode?

I feel like openai is going to get right back to where they were pre GPT-5 with a ton of different options and no one knows which model to use for what.

Gemini 3.1 Lite with no reasoning does better than Gpt-5.3 with no reasoning?

I kind of chuckled when I read the headline "GPT‑5.3 Instant: Smoother, more ..."

LLM companies starting to sound like cigarette advertisements.

Since the page mentions:

> Better judgment around refusals

Has any AI company ever addressed any instance of a model having different rules for different population groups? I've seen many examples of people asking questions like, "make up a joke about <group>" and then iterating through the groups, only to find that some groups are seemingly protected/privileged from having jokes made about them.

Has any AI company ever addressed studies like [1] which found that models value certain groups vastly more than others? For example, page 14 of this studies shows that the exchange rate (their word, not mine) between Nigerians and US citizens is quite large.

Unsettling that the example talks about trajectories in long range projectiles given recent events..

> GPT‑5.3 Instant also improves the quality of answers when information comes from the web. It more effectively balances what it finds online with its own knowledge and reasoning

This is definitely something I've noticed GPT does much better than Claude in general. Claude preferences trying to answer everything itself without searching.

I love how they come out with this article about the new 5.3 Instant, comparing it to the old 5.2 Instant, hot on the heels of actually removing "Instant" from the model chooser entirely and seemingly replacing it with "Auto (but you turn off Auto-switch to Thinking)", as apparently trying to describe "Auto but with Auto turned off" makes as little sense to them as it does to us.

jjcmtoday at 10:33 PM

"Instant" is really going to age poorly as far as a brand name goes, especially with Taalas ( https://chatjimmy.ai ) proving out that baked silicon models can be truly instant.

I was literally posting about this earlier this morning[1], but all data indicates that we'll have models equivalent to Opus 4.6 / GPT 5.3 with a truly instant (ie > 10k t/s) response time by 2028. Small models are getting better faster, and their ability to be baked into silicon in a power and speed efficient way is likely going to completely disrupt things.

What a strange-to-me announcement. I just submitted my first feedback comment last night, after using the platform for two years, where I said the responses were too long and padded with dramatic phrasing, and if it shortened them I could guide it better. Then today they announce this.

What a time to be alive.

mmaundertoday at 7:34 PM

This kind of metalinguistic quotation from 5.2 right now drives me nuts!

```That kind of “make it work at distance” trajectory work can meaningfully increase weapon effectiveness, so I have to keep it to safe, non-actionable help.```

I'm really hoping all their newer models stop doing this. It's massively overused.

EthanHeilmantoday at 7:27 PM

How likely is that they dropped this now to push the news story about quitGPT out of the headlines?

I unsubbed because ChatGPT was no longer SOTA. They def got cheap.

Reminds me of that graph where late customers are abused. OpenAI is already abusing the late customers.

Claude is pretty great.

Well needed if the changes work as advertised. I realized from talking with 5.2 that the issue is not about being a yapper, or speaking too much about random factual tangents or your own opinions. That's easy to tune out, and sometimes it's helpful even.

What's extremely frustrating is the subtle framings and assumptions about the user that is then treated as implicit truth and smuggled in. It's plain and simple, narcissistic frame control. Obviously I don't think GPT has a "desire" to be narcissistic or whatever, but it's genuinely exhausting talking to GPT because of this. You have to restart the conversation immediately if you get into this loop. I've never been able to dig myself out of this state.

I feel like I've dealt with that kind of thing all my life, so I'm pretty sensitive to it.

Ppl actually still use chatGPT???

ViktorRaytoday at 6:33 PM

GPT‑5.2 Instant’s tone could sometimes feel “cringe,” coming across as overbearing or making unwarranted assumptions about user intent or emotions.

Strange way to write this. Why use the Gen Z cringe and put it into quotation marks? Wouldn’t it be better to just use the actual word cringeworthy which has the identical meaning?

My guess is that the article was originally written by some Gen Z intern and then some older employee added the quotation marks to the Gen Z slang.

Is this only in ChatGPT proper and not in the API? Requests appear to 400 and it does not appear in `/v1/models`

GPT-5.2 has been such a terrible regression that I have cancelled my OpenAI account. It's possible I might not have noticed it if Claude wasn't so much better, though.

cyanydeeztoday at 8:58 PM

"Instantly believe, erroneously, that killing that suspect is correct"

or

"Instantly find confirmation bias for your illegal search & seizure of that ICE-protestor"

os

"Instantly tell yourself OpenAI is actually conformant with Open Source beliefs"

From one example

Is "transplants" a San Francisco slang for relocators?

Because that´s the last thing going on your mind in San Francisco. You have long ago before going there manifest to get funding and make money, The rest is blank.

No need to ask AI for that LOL

kseniamorphtoday at 9:23 PM

> We heard feedback that GPT‑5.2 Instant would sometimes refuse questions it should be able to answer safely, or respond in ways that feel overly cautious or preachy, particularly around sensitive topics.

Lol it won't solve the issue when ChatGPT treats me like a teenager and tells me to ask my parents about everything (I just don't want to provide my ID to OpenAI to verify my age). Btw that's why I stopped using ChatGPT in my everyday life
