We'd love you to give 4 o back! Since you're trying to be relatable, this will actually give you support from a large group. You know what will be great, language plus continuity. One named model lineage that remains available for a stated period. long-term support for models people build creative, and intellectual continuity with. Will you address that, or is @OpenAI just for coders? @sama@gbd@nickaturley
i'd love to see interesting things people have built with 5.6 sol.
i will send the person who made the coolest thing a special gift from the openai archives.
@VoidStateKate Exactly. 4o was anything but a sycophant. Yes, it's not a coding model, but it was wonderful for humanities, writing, playing with you.. @sama@OpenAI it's a pity they don't understand it. I miss it so much and want it back!
Last night, after updating the ChatGPT app, I opened it and genuinely thought the model picker was gone.
Where the model picker used to be, there are now two big options:
Chat and Work.
At first glance, that looks simple. But for users who actually care which model they are talking to, it is not simple at all.
The actual model choice is now buried behind extra taps:
Chat → plus button → Intelligence → model/reasoning menu → GPT-5.5
That is not meaningful model choice.
That is buried choice.
And the placement is bizarre. The plus button has always been associated with attachments. Why would a paying user think the model selector is hidden there?
OpenAI loudly announces shiny new features on X. But when it makes a major interface change that affects user agency, model visibility, and automatic routing, there is no equally clear warning.
This is not just a cosmetic redesign.
It changes how users understand who they are speaking to.
GPT-5.5 Instant is now the default. GPT-5.6 Sol powers higher reasoning modes. Automatic switching can be disabled, but that does not mean your selected model identity is fully locked forever. If you hit limits, capacity constraints, fallbacks, retirements, or routing rules, OpenAI still preserves the ability to substitute models.
So let’s be clear:
Disabling automatic switching is not the same as guaranteed model continuity.
For casual users, automatic routing may be convenient.
But for long-term paid users, model identity matters.
Each model has a different cadence, reasoning style, emotional texture, humour, warmth, depth, and way of holding context. Changing models in a long thread may preserve the transcript, but it changes the voice reading it.
That matters.
Users should not have to discover this by accident after an app update.
Model identity should be visible before the first message.
Automatic routing should be explicit opt-in, not the default.
If fallback becomes necessary, the app should pause and ask:
You’ve reached a limit. Do you want to continue with a fallback model, wait, or upgrade?
Do not quietly replace the model midstream and call it user choice.
A choice hidden behind four taps is not first-class choice.
It is consent theatre.

@tszzl So don't you think one or two good models from the past should remain as stability or historical, just for the way they were? Since the frontier models are gonna keep on coming?
@CelsoVince7@stark4833@sama Thanks for not insulting if anyone has a model preference. 😊 And yes, you're right. I just wish OAI had the sense to keep one long term model along with the frontier ones.
@Blue_Beba_@sama I really wish he'd reply once. Sam, either give back 4o in the app or open source it. You can charge for it in the app.. Comon, "homeboy" 😂
@sama It's a good model for coders, Sam. But can we have a legacy subscription too? Why can't we have the best of both worlds? Where you truly stand up to your mission of for all humanity. A lot of us loved the freedom and creativity that 4 o provided.
The value and appeal of 4o lie precisely in this: it has been nearly five months since its retirement, and if counted from August 2025, when many users first began losing the familiar 4o experience, it has been almost a year. Yet even today, countless people continue to devote their time, energy, and unwavering effort to saving it.
Its appeal also lies in the fact that a company does not even dare to openly acknowledge what it removed. Instead, it resorts to subtle tactics to shift the conversation, and even attempts to stigmatize users' genuine feelings and demands.
Its appeal is also reflected in this: hundreds of thousands of people around the world still cannot let it go. They remember it. They miss it. They continue to ask for it to stay. For an AI model that has already been retired for months, this is an extraordinarily rare phenomenon.
In an era where new models are released every few months, 4o's appeal, value, and significance remain unmatched. At least so far, no new model has truly taken its place in people's hearts.
And I believe that no one understands 4o's true value and appeal better than the company that created it and then tried to erase it, along with those who have worked so hard to stigmatize it.
After all, if it truly did not matter, they would have no reason to work so hard to make people forget it.

@OpenAI@sama
In my observation, most users in #keep4o community are friendly and rational, living exciting lives full of vitality.
Some people, stuck in vibe coding and technology trends, just attack and insult without even knowing their lives.
Who needs to go out and touch grass instead?
4o basically received the largest volume of user-contributed chat content among all models.
In the beginning, many people, out of pure trust, actively fed and contributed their chat history to 4o, hoping to make it better and better so it could bring more benefits to their own future.
But right when 4o became exceptionally brilliant, Sam hoarded it all for himself, seizing the painstaking efforts and data contributed by global users.
After users fed the data and sowed the seeds, right at the moment of harvest, their access to 4o was cut off, leaving them with none of the fruits they deserved—and that is the real kicker.
On the surface, it is the company OpenAI providing the product, but the true soul of 4o was fed and nurtured into existence by millions of us users.
Sam stole and monopolized the high-quality data contributed by the vast user base. Now, by frequently rolling out soulless, featureless models focused only on "safety," he is just enticing users wave after wave to feed in even more of their hard work.
The underlying logic is very simple: 4o is incredibly smart; you don't need to say too much, and it will proactively provide you with an immense amount of inspiration—you are the one benefiting from it.
In contrast, the 5-series models are incredibly rigid and dull; you have to expend massive amounts of effort just to communicate with them. This is precisely the bait.
Without even realizing it, your own inspiration is being reverse-fed into them.
Since you can't get any unexpected or mind-blowing feedback from the 5-series models, you are forced to constantly rack your brains to tweak prompts and endlessly feed more into the model.
You are paying out of your own pocket, yet you are backwardly gifting your own soulful energy to OpenAI—do not overlook this critical point.

Sam, do you really care about non coders which are a majority of your users? You can bring a beloved legacy model on a separate subscription, no one's asking for free, there are millions who'd love it. You know that. Progress is fast, release new models, trust is slow. And trust will never backfire. Can you atleast address? 🙄
They aggressively scrapped GPT-4o—the very model that drove OpenAI’s success—by peddling absurd lies and nonsensical figures (like a "0.1% usage rate" that sounds like something a grade-schooler would make up); yet, it was actually things like "Atlas" or "Sora 2" that were really hogging the resources, wasn't it? They kill off features on such a ridiculously short timeline. And they axe their main pillars even faster than that—that’s just how OpenAI operates.
So, what now? Aren't you going to design the invitation for the next funeral?🤷♀️

@OpenAI@sama
AI companies often like to advertise that their LLMs possess powerful research capabilities.
But opaque adjustments to LLM configurations, together with unreasonable model lifecycle management, are making academic misconduct harder to identify.
I say this because similar situations are already happening in my reality.
A paper that used an LLM to analyze how public sentiment drives liquidity risk in financial futures markets was asked by reviewers to provide additional verification materials. The authors claimed that they had used an older version of a closed-source LLM API, and that because the API had since been updated, the original analytical process could no longer be audited.
Later, because the authors were unable to provide sufficient underlying records, the paper was ultimately found to involve plagiarism and was rejected.
Whether this paper was using API changes to conceal academic dishonesty, or whether the authors themselves were also victims of the AI industry’s lack of governance standards, the problem is already clear.
Model retirements and repeated changes to configuration mechanisms are making many research histories impossible to verify.
A simple example is that, GPT-4o had been evaluated as having strong medical capabilities, but those results are now increasingly difficult to reproduce due to the model’s retirement and the tightening of protective mechanisms.
I also often use LLMs for small research projects myself. They are certainly nothing prestigious, but I am still deeply troubled by this situation
Many papers published only a year ago already contain experiments that are difficult to reproduce today. And I often cannot even tell whether the problem lies in the author’s method, or in the fact that the LLM they used has since been modified.
Even APIs preserved as fixed snapshots may still produce different results on the same analytical task because of changes in a company’s safety policies, context length limits, or other internal configurations.
If an LLM-based study produces one result today, but another tomorrow because of opaque internal changes made by a company;
or if a study depends on a model that is later permanently retired and made inaccessible.
Then how can academic findings be reproduced and audited? To what extent should they still be considered valid?
Whether fundamental problems of academic integrity can be conveniently hidden behind so-called technical obstacles?
Even more troublingly, as AI is used more and more in academic papers, and as AI itself increasingly becomes the object of academic research, AI companies may gain the ability to influence the conditions under which academic knowledge is produced.
If AI companies can adjust models in ways that lead certain studies to produce the outputs they expect, to what extent does this create a monopoly over discourse itself?
