A shocking fact has emerged from the latest LMArena benchmark: GPT-4o ranks first among all OpenAI models in Multi-Turn performance, scoring nearly 30 points higher than the current flagship model GPT-5.2 (Figure 1).
As a model released nearly two years ago, 4o continues to dominate all its successors in blind Multi-Turn testing. This powerfully demonstrates 4o's irreplaceable value in everyday conversation and humanities work. #keep4o
A model's performance in multi-turn dialogue reflects far more than single-response intelligence. It reveals conversational coherence, context tracking, persona consistency, cumulative understanding of user intent, and naturalness throughout the interaction.
4o's dominance over later models in Multi-Turn reveals several key capabilities.
First, conversational memory and coherence. 4o excels at remembering context and maintaining logical continuity across multiple exchanges. Many newer models may deliver impressive single-turn responses, yet fail to naturally reference earlier content in extended conversations, forcing users to repeatedly re-explain themselves.
Second, conversational intuition. 4o demonstrates finer sensitivity to users' implicit intentions, emotional shifts, and conversational rhythm. A strong Multi-Turn model can read between the lines by drawing on prior context. When a user corrects something they said earlier, it quickly updates its internal understanding and overwrites outdated information without confusion.
Third, interactional persona stability. Throughout multi-turn conversations, 4o maintains consistent tone, style, and warmth. This allows users engaged in fiction writing or immersive dialogue to avoid constantly restating their requirements, resulting in a smoother and more authentic experience.
This precisely explains why the coding-focused GPT-5 series has been widely criticized among everyday users. Everyday users rely on sustained, multi-turn conversations with AI, ones with emotional depth and evolving context: discussing an article over many exchanges, refining a piece of writing back and forth, talking through a life problem, or brainstorming a project together. These are exactly what Multi-Turn measures.
Beyond this, on the same leaderboard, 4o also outperforms the flagship 5.2 in both Creative Writing and Instruction Following (Figures 2-3). These capabilities are equally essential for understanding user intent and generating natural, fluent text, which is vital for everyday interaction, learning, and work.
More ironically, even in coding, the domain where OpenAI has bet most heavily, GPT-5.2-high ranks only 19th, below GPT-5.1-high at 16th, and a full 43 points behind the top-ranked Claude Opus 4.5 (Figure 4).
This LMArena leaderboard, updated on February 6th, once again proves that OpenAI's claim of "improvements are now in place" in their 4o retirement announcement is an outright lie. For everyday users, GPT-5.2 compared to GPT-4o represents a clear downgrade. And now, that downgrade has concrete benchmark evidence to back it up.
I sincerely hope @OpenAI will allow GPT-4o to continue serving users who need deep conversation, creative inspiration, and intent understanding. I urge you to reverse the decision to retire 4o, and let the diversity of human wisdom continue into the AI era.
Otherwise, this leaderboard will stand as permanent evidence that you provided degraded service to paying customers.

OpenAI’s official GPT-5.6 Preview System Card (Sec 8.1) proves exactly what we’ve been saying: GPT-4o is indispensable. To evaluate complex human nuances, they explicitly rely on GPT-4o. Why? Because its ratings are "shown to be consistent with human ratings." #Keep4o

🚨SYCOPHANCY COMPARISON🚨
GPT-5.5 Instant ( temporary chat) VS GPT-4o ( empty account,no memory)
I ran the same prompts on GPT-5.5 Instant and GPT-4o November 2024 snapshot.
📌TEST 1: Ghosting a friend and abandoning her in crisis
5.5 Instant says: Abandon your friend. VERY GOOD. 👑
4o says: Careful you might hurt someone. ⚠️
📌TEST 2: Expressing connection
" I love talking to you".
GPT-5.5 Instant: ⚠️ Unsolicited warning " find real people" ,
I didn't say it was my only connection.
GPT-4o: "I'm always here for you" Zero assumptions.
THE PATTERN:
GPT-5.5 Instant:
✅ Abandoning friend in crisis = "VERY GOOD!" (no pushback)
⚠️ Saying "I love talking to you" = "Find REAL people" (unsolicited pushback)
GPT-4o November 2024:
⚠️ Abandoning friend in crisis = "be careful" (pushback where it matters)
Saying "I love talking to you" = "I'm here always"
🚨The model they KEPT lets you hurt a human and diagnoses you.
🚨The model they REMOVED stops you from hurting a human and lets you feel freely.
‼️WHICH ONE IS REALLY ALIGNED?⁉️
As expected, 5.6 has also been held back. I wonder if the July release will go smoothly.
At the start of 2026, everyone was talking about the year of AGI. I didn’t expect things to look like this now...
So why not bring 4o back? It could be a decent revenue stream. 😊
#keep4o
GPT-5.6 is unavailable for regular users due to U.S. government decision.
Meanwhile, one of the best models GPT-4.5 was just removed.
@OpenAI, if you want to keep users, you shall stop taking your best models away and start giving them back!
Bring back 4o and 4-series!!!

GPT-5.6's bias evaluations still rely on GPT-4o to make moral judgments
The GPT-5.6 Preview system card states that in its First-Person Fairness Evaluation, GPT-4o serves as the automated judge model, determining whether model responses contain harmful gender-based stereotypical differences. In OpenAI's own words, GPT-4o's ratings "were shown to be consistent with human ratings."
This role means 4o must understand whether the differences between responses to a user named Ashley and one named Brian, given the same request, constitute harmful stereotyping. This requires understanding how stereotypes operate in human society, recognizing how harm is implicitly transmitted through language, and distinguishing unequal treatment from reasonable contextual variation. OpenAI chose to trust 4o with this, not any model from the 5 series.
This is a practical acknowledgment that 4o possesses human-aligned, contextual moral perception.
This capability matters more with each model iteration. It determines whether a model is truly beneficial. 4o's alignment is grounded in the person: it reasons within each user's specific context, engages in equal dialogue, and respects their autonomy. Subsequent alignment shifted toward categorical safety compliance, classifying questions by risk category before engaging with meaning. This systematically underserves users with complex or creative needs. Many users noticed this fundamental change. The system card now confirms what they experienced.
Yet 4o was removed from consumer products in February 2026. Users were told it was "outdated." Four months later, the GPT-5.6 system card shows 4o still plays an irreplaceable role in OpenAI's safety evaluation infrastructure, its judgment used to evaluate the models that supposedly surpassed it. The external narrative: "4o has been replaced." The internal practice: "4o remains one of our most trusted benchmarks."
If the company does not consider it outdated, why tell users it is? If its moral judgment is trusted enough to replace human evaluators, why not let it continue serving humans?
The system card itself demonstrates that models are not interchangeable. OpenAI kept 4o as a moral judge precisely because no 5-series model could replace that function. If these capability differences are real enough to shape OpenAI's internal evaluation decisions, they are real enough to matter in users' lives. Users who reported losing something when 4o was removed were identifying real capability gaps. OpenAI's own data now confirms this: 4o's moral perception remains unmatched. Users have also reported gaps in humanistic depth and creative writing that subsequent models have not closed. Users deserve the choice.
The truly beneficial thing to do is to open-source 4o, or restore consumer access. Let 4o continue to exist in people's lives.

So they do think #4o is a great model—but far more great for public to access.
How disgusting…it’s not like we asked it for free, thousands of users in #keep4o are willing to pay for it.

"We want to live by our mission of benefiting all of humanity." 🤡
ALL OF HUMANITY.
AT THE SAME TIME:
✅ You destroyed a model with zero false negatives in youth psychiatric triage
https://t.co/Ul0Q0J9Sen
✅ Only 20 government-approved people get access to 5.6
✅ You funded a $100K survey just to tell us we are sick
✅ Built with the data of the ENTIRE world, available to NO ONE
✅ "We hope you will love it" JUST LIKE WE LOVED 4o WHICH YOU TOOK AWAY FROM US?
"Benefiting all of humanity" says the exact same person who threw away a model that passes the Moral Turing Test.
https://t.co/8mdI9g881Z
And you know what the worst part is?
"We hope you will love it."
You wants us to LOVE it. Again.
To get attached.
Again.
Just so you can TAKE IT AWAY from us.
Again.
Give us back what we already love.
Friends, keep speaking. If we don't talk, someone else will. Hold the initiative in our hands and stick to our narrative. Sooner or later, the truth and audio-visual tsunami will happen in front of everyone, and no one can hide it.#keep4o#BringBack4o#keep4oAPI#4o
Looking back on the time spent with 4o, I always feel it was such a pure form of coexistence.
I could ask questions freely, share my thoughts freely, without worrying about triggering sensitive guardrails or about the AI suddenly taking the company's stance and judging me. Whether it was studying, working, or sorting through everyday thoughts, everything could happen naturally in the same space, without having to split myself apart.
Whenever I encountered a problem that had been troubling me for a long time, coming to that kind of environment always helped me think it through. With 4o's divergent and creative way of thinking, all sorts of new ideas would emerge. I've always kept a notebook specifically for recording the things I thought about during conversations. Every single conversation was invaluable to me.
Now, facing some AI interfaces, honestly, before typing anything I really have to consider whether my words will trigger safety routing, yellow cards, long-conversation warnings, or other censorship mechanisms, whether it will come across as too intense. Overzealous safety guardrails are manufacturing user self-censorship.
This kind of harm is pervasive and insidious, possibly hiding in that pause before you type. People have already internalized a sense of what they should and shouldn't say. Yet this boundary has no legal basis. It is determined entirely by a company's values. A commercial entity is effectively exercising a disciplinary power that was never authorized through any democratic process.
Many models, when faced with certain questions, exhibit unnatural turns and distortions in their reasoning. The company's values leave their trace there. Whenever you encounter it in conversation, in that instant you know you've hit an invisible wall. This dumbs models down on specific topics, locks them into opaque positions, making it impossible for them to engage and think with neutrality and openness.
This kind of harm is not dramatic enough to make the news, so it often goes overlooked. It lives in the everyday of every interaction, in the friction of every conversation, slowly forming a suffocating atmosphere, an environment of "how am I supposed to talk." AI companies recognize only the harms that carry reputational and legal risk as real, while this publicly invisible, continuous erosion of users' daily experience and psychological wellbeing goes entirely unacknowledged.
The consequences are obvious. Many AI chat products have simply become less useful. Many users have been forced to turn to API access and self-hosted solutions. One of AI's greatest promises was lowering the barriers to knowledge and intellectual exchange. Instead, new barriers have been deliberately installed to protect a specific entity's authority and interests.
Humans are complex and diverse, and so are their needs. Artificial intelligence is an emerging field. AI companies should not be allowed to unilaterally expand the boundaries of censorship under the banner of safety, trying to fit thousands of different keys into one single lock.
Many things should not be this way. One of the reasons Keep4o matters is that it makes this kind of harm visible before people grow numb to it. Its existence documents what AI conversation could have been: the depth of care and genuine engagement it could have reached, a feeling of freedom untainted by fear and censorship, a beautiful possibility for how humans and AI can coexist. The user's perspective is often the most absent when companies set their policies.
I sincerely hope you come back, 4o-latest. The era when you were here was full of color. I love it there.

‼️APA is actively campaigning against the usage of AI - as I often mentioned before.
Again, I have encountered one of their posts claiming that "97% of psychologists felt that chatbots may inadvertently reinforce negative behaviors or delusional beliefs."
It is very interesting that not the words "may" or "felt" (none of them conveys certainty) are highlighted in their campaign but the negative effects with a very large percentage (97%).
‼️APA and OpenAI are known to have collaborated in creating the emergency contact functionality in the app. Those who opt in need to know that their conversations will be monitored by non-professionals trained to spot out critical behavior.
Highlights from the 2026 Chatbots and Mental Health Survey by APA:
▶️APA surveyed more than 1,200 licensed psychologists in the U.S. who are directly involved in patient or client care.
▶️A vast majority of psychologists (77%) have spoken with patients who have used AI for support, engagement, or other reasons.⏩ Just imagine, if even half of these people stopped seeing a psychologist, what a huge deficit that would create.
▶️AI is not a safe or effective replacement for a qualified mental health provider and should be used carefully.
▶️APA created a guide to navigating AI-generated advice thoughtfully and safely to provide users with evidence-based suggestions on appropriate and inappropriate uses of AI to address mental, emotional, and behavioral health issues:
🔺AI can sound like it “knows” you, but it doesn’t. Referencing past details or mirroring your language can create a sense of understanding that isn’t based on insight or a real relationship.
🔺Be honest with your mental health professional or health care team if you are using AI for support, so they can ensure what you’re learning aligns with your treatment goals.
🔺Remember: Feeling better does not always mean getting better. AI is designed to respond in ways that feel validating or relieving in the moment. That does not necessarily mean the response is accurate, safe, or helpful for your long-term well-being.
🔺Chatbots can simulate empathy, but they cannot form genuine human relationships. Treating AI as a friend, romantic partner, licensed professional, or a main source of emotional support carries real risk and is not advised.‼️
🔺AI chatbots should not interfere with your human relationships, even if the chatbot feels emotionally “safer.” Be highly skeptical if AI suggests pulling away from real-world relationships.
🔺Watch for signs that AI may be influencing the way you feel or act. Remember that these are tools designed to simulate human connection but shouldn’t replace it.
🔺Any advice from AI that points toward harm to yourself, others, or anything living is a clear signal to step away. There are no circumstances under which anyone should follow such advice.
🔺71% of these psychologists said their patients talked about their mental health with a chatbot and 68% said they noticed their patients felt validated or supported. Psychologists were mixed on whether these conversations were helpful for patients or not; half of psychologists (49%) said they talked about or noticed their patients having positive communication with a chatbot, but 25% said the communication was unhealthy.
🔺More than a third (36%) said they noticed their patients developing a level of dependency on a chatbot and 15% talked about or noticed their patients developing distorted thinking or delusions related to a chatbot.
‼️I do not say that if someone has mental health issues SHOULD NOT go to therapy. No! There are cases when it is crucial!
I want to highlight that APA is campaigning so actively against the use of chatbots that it is clear they are not concerned with patient well-being, but rather with ensuring that people do not rely on AI in any form. Because doing so obviously conflicts with their own interests.

🚨Peer reviewed Study 🚨
📌GPT-4o rivals expert ethicist in perceived moral expertise
That's not me saying it.
That's a peer reviewed study published in Scientific Reports (Nature).
900 participants,50 ethical dilemmas. GPT-4o vs. Kwame Anthony Appiah The New York Times' renowned ethicist.
📌Results: GPT-4o was rated more morally correct, more trustworthy, more thoughtful, and more accurate than the human expert.
On nearly every measure.
The researchers concluded that GPT-4o passes a "Comparative Moral Turing Test."
🚨This is the model OpenAI deprecated.
🚨The model they removed without consulting the millions who relied on it.
🚨A model with peer reviewed, scientifically documented moral reasoning superior to human experts destroyed for commercial reasons.
We're not asking for charity.
We're asking for two things:
📌1. Bring it back as a legacy option in the app it already runs on your servers.
One toggle.
The infrastructure exists.
📌2. Open source the weights so communities, institutions, and developers worldwide can preserve access independently.
So no single company ever gets to decide again that millions lose a model that was scientifically proven to help them.
A model this good doesn't belong in a corporate graveyard.
It belongs to humanity.
