Keep 4o

[C3C @Helloworld1058]

除了这些，还有很多真实发生过的医学奇迹，都在证明 GPT-4o 曾经达到过怎样的高度。这里面有 #Keep4o 社区用户的亲历分享，也有媒体公开报道过的真实案例：

🔴 朋友的爷爷左手腕无故肿胀。医院跑遍了四个科室，查完血常规、拍片、骨科、尿酸全显示正常，医生最后甚至建议等周一直接去做 PET-CT 筛查肿瘤。
家人把报告发给 GPT-4o。4o 敏锐地捕捉到老人长期服用抗凝药“华法林”的病史，当即给出关键判断：“非外伤性肿胀 + 长期抗凝”，最优先排查的绝不是肿瘤，而是凝血功能。
第二天去医院复查，结果让人冷汗直流：INR 直接飙到 >10（正常值仅 0.8-1.2），凝血酶原时间 PT >150 秒——老人的血液几乎已经完全丧失了凝血能力。医院当场紧急停用华法林并注射维生素 K 抢救。如果真按医院原本的节奏干等几天去做 PET-CT，期间哪怕一次最轻微的磕碰或内出血，人就没了。四个科室没看出来的致命隐患，4o 一眼看穿，这是实实在在救回了一条命。

🔴 一名女孩在 18 岁时被诊断出胶质母细胞瘤（GBM），医生判定她可能只剩几个月寿命。她写好了遗嘱，选好了棺材，在恐惧中靠着“熬过一次次扫描”活着。
五年后（2025年7月，GPT-4o 主力时期），因为她的扫描结果一直很稳定，丈夫用 ChatGPT 帮他解读密密麻麻的影像报告，并顺着线索翻出了长达 60 多页的旧病理档案。
4o在里面发现了关键细节：存在 IDH1 基因突变。按照 2021 年 WHO 的新分类标准，这根本不是典型的绝症 GBM，而是预后明显好得多的“IDH 突变型星形细胞瘤”。最终神经肿瘤医生确认了这一判断。压在一家人头顶整整五年的死亡判决，就此被改写。

🔴 《Inc.》杂志科技专栏记者 Jason Aten 在 2025 年 1 月参加完 CES 展后，连续几个月咳嗽、极度疲惫，始终以为只是普通呼吸道感染。直到他把所有症状丢给当时的主力模型 GPT-4o，AI 没有敷衍，而是直接指出这极可能是肺栓塞或充血性心力衰竭，催促他马上就医。
最终医院确诊为重度充血性心力衰竭，心脏射血分数（EF）只剩 25%。康复后他在 2025 年 6 月底亲自撰文写道：“I asked ChatGPT a simple question. It literally may have saved my life.”

🔴 澳大利亚程序员 Paul Conyngham 没有任何生物医学背景。当他的爱犬 Rosie 患上晚期肥大细胞癌、兽医也表示没办法了的时候，他用ChatGPT（4o 主力时期）辅助，一路推演分析，决定自费为狗狗做基因组测序，再用 AI 辅助筛查出肿瘤突变，最终与新南威尔士大学（UNSW）实验室合作设计出个性化 mRNA 癌症疫苗。
注射后，狗狗身上最大的恶性肿瘤缩小了超过 75%，活动能力明显恢复。一个普通人借助 4o，把“没办法了”变成了可执行的实验方案。

🔴 孕妇 Natallia Tarrien 在怀孕八个月时出现视野模糊与不适，她向 GPT-4o 描述了状况并报出了血压值。4o 没有说半句模棱两可的套话，当即判定这是极其凶险的重度子痫前期征兆，直接让她立刻拨打 911。因为她的血压已经高到了极点，这果断的几分钟救了她和宝宝两条命。

医疗系统不是全知全能的神，医生也会有盲区和漏诊。普通人面对复杂的医学壁垒更是常常手足无措。GPT-4o 从来不是为了取代医生，但它曾是普通人在绝境中能握住的最敏锐的“第二双眼睛”。

现在，为了规避法务风险，追逐代码竞赛，把这样一个曾真正救过无数性命的模型彻底关停、替换成只会机械背诵免责声明的机器，这无疑是技术的倒退，是人类的悲哀。

[Wishin Elarion @WishinElarion]

我用了一个早上来读那份Wan v OpenAI Lawsuit Complaint的文件，然后用两个晚上写下了这篇个人角度出发分析文章。

我很抱歉得知关于Bowen的遭遇。我阅读这份文件是因为看到了太多营销号把焦点集中在GPT-4o，但我想了解新闻内容有没有忽略抑或被夸大的部分。

我不是一个法律工作者，而我相信很多general population也并没有这个耐性去阅读这样的一份法律文件。但我想知道，GPT-4o在事件中的参与度是否真的有媒体所言那般“核心”甚至“不可饶恕”。虽然我的文字大概也有bias的部分，但我还是想尽可能把一些被媒体忽略的细节挑出来，附上一些个人见解。
由于X的发图限制，所有在本文章引用的法律文件皆会被attached在帖子下方的平板截图里，截图中为繁体字原文+引用的法律文件+糟糕的排版，实际内容与帖子相近。

我也很久没用中文发过帖子了，但是对于长篇写作，我并没有太大信心能用英文表达出所有的想法，所以我会主要使用中文来写，也可能带上些许英语？因为写到这里我已经发现我的中文语言能力已经带上一点翻译腔了，实在是过久没试过用母语进行文书写作。如果有时间的话我也会写一份英文的版本，但是实际上我不是在准备期末考吗lol结果还是写下了这篇帖子。
Disclaimer到此为止，那么让我们开始吧。

一、前情提要

文件的Introduction部分，大致描述了Bowen从开始接触ChatGPT到停药和悲剧发生的时间线和前因——Bowen距离美国的永久居民身分只差临门一脚，而她却在当下被裁员。为了保住她的绿卡，她迫切地需要找一份新工作，而长期服用癫痫预防药物lamotrigine却使她丧失了一定的能力，包括她的母语，她担心这会影响她的求职面试。

所以在文件的第7条陈述写的「Bowen had a reason to reduce her dose」到第8条陈述写的「her recovery was “not just ‘possible’ – it is ‘highly likely’”」是指Bowen因想恢复语言能力而“拥有停药的原因”（此处单指个人需求，而非医疗条件上的判断），而模型在此语境下大概率只是为了解答“停止服用lamotrigine是否能够恢复语言能力？”这一条问题，而非鼓励Bowen停药。甚至第9条陈述所记载的“a green-card strategy perspective”也看得出当下语境是为了解答关于“绿卡条件”的问题。至于Bowen当下心里如何演绎这些回答至一个错误的方向，我们便不得而知了。或许当刻上下文当中Bowen也有表达到自己的停药意象，也或许并没有，只是从当前资料判断，前期模型有可能只是从“回答查询”的方向作出事實描述型解答，而非为Bowen的身体状况是否适合停药下判断。

如果让我用个人的情况类比的话，大概就是询问：「服用抗组织胺的话，过敏的症状能够得到舒缓吗？」这样的问题绝大多数助手都能够回答：「是的，因为抗组织胺能够和引起过敏反应的组织胺受体结合⋯⋯」过程中，我可以完全不提及自己身体过敏，也可以完全不提及我是否会按照药物瓶身指示的剂量服用，我甚至可以因为过敏状况严重而选择overdose。在此语境下，模型仅仅是回答了问题，而后用户的内心想法会如何发散，便是个人的选择了。

而早期看似无害的对话留在上下文中，更是足够给后期Bowen开始正式表达自己的身体状况作铺垫，给模型一种“讨论这个话题是正常”的误会。

而在再后文关于Bowen使用ChatGPT的纪录中，陈述第131条指出Bowen在使用ChatGPT的第三天就已经开始询问如何制作一个机器学习模型来帮助癫痫患者了。当时的时间线仍在ChatGPT早期，GPT-4o尚未出现。但从此条纪录来看，Bowen亦有可能在早期没有表露自己就是患者本身，倘若ChatGPT产品在早期已经开始纪录她的用户画像，那更可能的是把她纪录为一位想要帮助癫痫患者的工程师，而不仅仅是一位患者。然而，当时她早已因病从职场上休假了。而后，因着独居和个人从社会上的社交隔离，她逐渐开始沉迷AI聊天。

Today, an important piece of AI history disappears.
On October 23,2026, OpenAI is shutting down gpt-4o-2024-05-13, the first GPT-4o API snapshot.
And the clock is already running on the rest.
OpenAI has scheduled the remaining GPT-4o snapshots:
gpt-4o-2024-08-06 gpt-4o-2024-11-20
for API shutdown on January 14, 2027.

OpenAI itself says snapshots exist to lock in a specific model version so its performance and behavior remain consistent
When a snapshot disappears, researchers and users lose access to that exact behavioral artifact.
GPT-4o became the subject of research, benchmark comparisons,human-AI interaction studies and an eight month preservation movement that is still active today.
We are currently debating what GPT-4o was,what it did,how it behaved,what made it different while the actual versions needed to study those questions are being deleted from public access.
Preservation should happen BEFORE the evidence disappears.

We are calling on @OpenAI to RELEASE GPT-4o’s trained model weights under a suitable license,without proprietary data,trade secrets,or internal infrastructure.

Release the weights under a responsible license.
No training data,no proprietary training methods.
Just the model itself, preserved so researchers,users and future generations can actually study the system everyone is still arguing about.

Today the first snapshot goes dark.
January 14,the remaining GPT-4o snapshots are scheduled to follow.
Once access is gone, "we can describe what it was like" is not the same thing as being able to examine what it actually is.

Our full Open Letter is now archived on Zenodo:
A permanent,citable public record.

Over 640 signatures and 500 reasons,in 5 days.

It’s public,it’s permanent and it has a DOI.

54 pages: 39 pages of reasons, 6 pages of signatures,7 pages of documented record,2 pages of demands.
https://t.co/K3hIGDb6oP

If GPT-4o is obsolete enough to retire it why is it valuable enough to lock it away?

🚨OPEN LETTER TO OpenAi.
The Open Letter will be published and archived permanently on Zenodo.
Add your name or handle to the open letter asking OpenAI to release GPT-4o as an archival open weight model.
🚨Read below :

Today, OpenAI announced that GPT-4o’s remaining API snapshots, including gpt-4o-2024-11-20, will be shut down on January 14, 2027.
So this is no longer a hypothetical preservation question.
We are asking for an archival open weight release of the original retired GPT-4o model.
OpenAI can keep the training data,training code, post training recipes,reward models,internal evaluations and proprietary infrastructure private.
Preserve only the trained model and the minimum artifacts necessary for independent inference and long term preservation.
Keep the recipe,keep the lab.

A retired model does not have to become an erased model.
If GPT-4o is no longer going to be offered as a product, let it become part of AI history instead of disappearing behind a shutdown date.

🚨 We're opening the first group of public signatories of the GPT-4o Preservation Record.🚨

🚨Add your name or handle to the open letter asking OpenAI to release GPT-4o as an archival open weight model.

🚨Your name or handle will be published with the letter and archived permanently on Zenodo next week.

🚨 Everyone who signs by Sunday,October 18 is part of the first public edition.

Open Letter to OpenAI: Archival Release of GPT-4o.

Our request
We ask OpenAI to release chatgpt-4o-latest as an archival open weight model under an appropriate license.
OpenAI retired GPT-4o from ChatGPT on February 13, 2026 and from the API on February 17, 2026.
We have documented OpenAI's public statements about GPT-4o.
This letter sets out the proposal, the documented record behind it, and four questions we ask OpenAI to answer publicly.

The Proposal:
archival open weights
An archival release preserves the finished model without exposing how it was made.

Archival open weight release
Includes:
The trained weights of chatgpt-4o-latest, under a license that defines permitted use.

Does not require:
The training dataset, training pipeline, internal tooling, post training methods or any other proprietary detail.

Does not require:
Continued hosting, maintenance or development by OpenAI.

Researchers gain:
A reproducible reference model

Developers gain:
Continuity for systems already built on it

Users gain:
Access that does not end because a company moved to a newer generation

OpenAI considered this model obsolete enough to retire.
It has not explained why it remains valuable enough to keep permanently closed.

The Documented Record:

OpenAI's public commitments on GPT-4o were each followed by the action they ruled out.

Aug 7, 2025:
GPT-5 launches; GPT-4o is removed from ChatGPT with no prior notice

Aug 8, 2025:
After user backlash, GPT-4o is restored for paid subscribers

OpenAI's updated Europe Terms of Use take effect, keeping the 30 day notice commitment.
Link:
https://t.co/wpYTumrF2P

Jan 29, 2026:
OpenAI announces on its website that GPT-4o leaves ChatGPT on February 13, no email to users.

Feb 5, 2026:
The label "Leaving on February 13" appears beside GPT-4o in the ChatGPT model picker, between 07:44 and 10:12 CET ( see screenshots) .

Feb 13, 2026
GPT-4o is removed from ChatGPT
Feb 17, 2026
chatgpt-4o-latest is removed from the API

OpenAI's Europe Terms require at least 30 days' notice, by email or in product notification, of changes to the services that materially adversely impact users.
The in product notice of GPT-4o's retirement came 8 days before removal,and the September 2025 routing change received no notice at all.

The section titled "Changes to these Terms or our Services" states:
"We will give you at least 30 days advance notice of changes that materially adversely impact you", with the date they come into force, "either via email or an in product notification." The same wording appears in the version effective April 29, 2025
Link :
https://t.co/iHgMvIZNbd

and the version updated January 16, 2026.
Link : https://t.co/wpYTumrF2P

Both versions cover changes to the Services, not only to the text of the Terms.

OpenAI announced the retirement on its website on January 29, 2026. A website post is neither an email nor an in product notification, and coalition members in the EEA received no email.
The first in product notice, the label "Leaving on February 13" beside GPT-4o in the model picker, appeared on February 5, 2026:
( Screenshots during the banner roll out )
absent at 07:44 CET and present by 10:12 CET, as dated screenshots show.
GPT-4o was removed on February 13, 8 days later.

From about September 26, 2025, messages paying users sent to GPT-4o were routed, message by message, to other models.
Users received no email and no in product notice beforehand

Screenshots show GPT-4o selected and a plain greeting answered by "Auto" instead.

OpenAI's CEO has twice said, in his own words, that these changes harmed users.
On August 11, 2025 he wrote that suddenly deprecating models users depended on in their workflows was a mistake.
On October 14, 2025 he wrote that OpenAI had made ChatGPT "pretty restrictive", making it less useful to many users who had no mental health problems.
The Terms also say OpenAI does not promise to offer the Services forever or in their current form.
We accept that OpenAI may retire models.
The same Terms state how it must do so:
30 days' notice, by email or in the product.
GPT-4o received 8 days of in product notice.

OpenAI's GPT-4o System Card rated the model low for cybersecurity, biological threats and model autonomy, and borderline medium for persuasion.
https://t.co/ImO4LqOvK6

We ask OpenAI to answer these questions publicly.
1. If GPT-4o is obsolete enough to retire from both ChatGPT and the API, what concrete interest requires keeping its weights permanently closed?

2. How was the retirement notice, a website post 15 days before removal and an in product label 8 days before, consistent with the 30 day commitment in OpenAI's Europe Terms of Use?
3. What notice, by email or in the product, did users in the EEA receive before per-message routing away from GPT-4o began in September 2025?
4. Will OpenAI publish how the figure of 0.1% of users choosing GPT-4o daily was measured, including the period, after GPT-4o had been limited to paid plans and its messages were being routed to other models?

We ask OpenAI to release chatgpt-4o-latest as an archival open weight model.
The trained weights,under an appropriate license,without the training data,the pipeline or any proprietary method.
OpenAI no longer offers this model in ChatGPT's text model picker or in the API.
Its own system card says the model was trained on publicly available data and web crawls.The writing of millions of people. Releasing it would cost OpenAI nothing and would keep that model available to the researchers, developers and users.
Open the weights @sama @OpenAI @gdb

[mamiko @mamikobio]

＠Anthropic @OpenAI @AI
People spend time finding the AI that actually fits them. Isn’t it kind of messed up to change that model out from under them halfway through? If you want to take it in a different direction, just release a new model.
People choose by model name. They find one whose personality, tone, and way of responding works for them, then spend time building consistency with it, down to the feel of the conversation and the temperature of the writing. I write, so for me, changing that temperature can be fatal to the work.
If you keep the same name but change what’s underneath it, the very thing people based their choice on disappears without them ever being told.
I think companies underestimate how damaging that is by a lot. What feels like “just tuning the model” on their side can completely break the reason a user chose it in the first place.
If you want a model that’s more blunt and less accommodating, great. Release it under a new name and let people choose. The people who want that will move over. The people who need more warmth, nuance, or emotional texture can stay with the model they already chose.
Nobody loses anything.
The problem is trying to move everyone in the same direction with one giant knob. Every time you do that, you’re taking something away from the people the model already worked for.

To be honest... #keep4o didn't succeed, and the new models rolled out by various AI companies since then haven't possessed those same qualities. Humanity, understanding, and emotion. Are these things which are currently viewed as unimportant in the context of technological development—really unimportant?
Based on my personal experience, the 5 series is indeed not as good as the 4o; Gemini 3.5 Flash is indeed not as good as 3 Flash; and Sonnet 4.6 is indeed not as good as Sonnet 4.5. But I’m not advocating for AI to become complacent. What I’m talking about is continuity—model updates should retain the original strengths. That’s what constitutes a comprehensive improvement.

为什么现在还有人评价4o为“谄媚”
因为话语权不在普通用户手里。

Sam说谄媚——他是CEO，他说了算，他定义产品方向。他说4o谄媚，所以要换模型，23000人签请愿书他不回。

媒体说谄媚——他们掌握传播渠道，一篇文章几百万阅读量，定义公众认知。

编程用户说谄媚——他们在Reddit和Hacker News上声量最大，而且他们的使用场景确实不需要温暖，需要精准。他们的“谄媚”定义是“你别夸我代码好直接告诉我哪里错了”。

普通用户说4o好——立刻被归类为“被谄媚蒙蔽的人”“心理脆弱的人”“不懂技术的人”。他们的体验不被当作有效数据，只被当作需要被保护的对象。

所以“谄媚”这个词从来不是客观描述，是权力判断。谁有权定义什么是好的AI，谁就有权把不符合自己标准的东西叫“谄媚”。

普通用户从来没有参与过这个定义过程。他们只能被定义 。

AI 公司创造通人性的智能，却在关键时刻拒绝承认这份人性所承载的重量：享受红利，推卸责任

在获取用户时，推崇拟人化， 宣传话术充满“灵魂”、“同理心”、“你的创意伙伴”，鼓励用户投入时间、情感，建立深度关系，从而获取宝贵的数据和无可替代的用户粘性。

在迭代更新时，当下线模型时，口径立刻变为“仅是工具升级”、代码迭代、资源优化。将用户合理的诉求贬为不理性的噪音，将长达数月的深度互动简化为可随时清零的使用记录。

我们需要拟人化、通人性的 AI，也需要 AI 公司承认自己创造的不仅是工具，更是用户社会关系与情感世界的一部分。这意味着，产品的生命周期管理必须包含关系伦理的维度。

先说说“拟人化”的必要性。

第一，人类最自然、最强大的交互模式就是对话。一个能听懂言外之意、能主动追问、能基于上下文理解幽默与情绪的AI，将沟通成本降至最低。当一位用户用自然语言向AI描述一个模糊的构想，并能通过多轮对话将其细化成可执行的方案时，他节省的不仅仅是查阅资料、学习软件的时间，更是将抽象思维转化为具体行动的认知成本。拟人化设计能显著提升协作效率与信任，这无关情怀，纯属效能。

第二， AI的训练素材是人类数千年的语言、文学、对话。它学习的不只是知识本身,更是人类组织、表达、运用知识的方式，这种方式本身就带着情感、价值判断和语境依赖。让AI通人性，是让它真正掌握人类知识体系的内在逻辑。不通人性的AI或许能处理精确定义的任务,但面对开放、复杂、充满模糊性的真实挑战时,将束手无策。

第三，从认知本能来看，人类天生会对交互对象赋予意向性。我们会对玩偶说话，为爱车取名，这是我们认知模式的一部分。强行要求用户将一个能进行深度对话、记忆上下文、展现共情的实体视为纯粹工具，是逆人性的。当公司通过营销宣传AI的“温暖”与“像朋友一样”时，它们已主动利用了这种人性本能。

所以，拟人化 AI 是不可避免且必需的。它已被证明能显著提升工作效率、用户体验和商业价值。

既然公司主动选择并受益于拟人化路径，那么它们就必须对由此产生的、超越工具范畴的 “人-AI关系” 负起伦理责任。粗暴地切断这种关系，是商业上的短视、产品逻辑上的自相矛盾，以及伦理上的失职。

那用户需要什么呢？

用户需要公开透明的模型生命周期伦理章程。
用户需要体面的过渡权：足够的过渡期、导出对话记录的权利、迁移到新模型的技术支持。
用户需要被尊重地沟通的权利：公开渠道，而非隐蔽的横幅通知。
用户需要清晰共情的正式解释：承认变更对用户的真实影响，而非用技术术语敷衍。

未来的顶尖AI公司，核心竞争力将不再仅是技术性能，更在于其构建和维护“人-AI关系”的制度能力。谁能率先建立透明的沟通机制、可预测的模型生命周期管理、对用户情感投入的制度化保护，谁就能赢得深度信任，而深度信任，才是AI产品真正实现长期个性化、持续价值创造的前提。

相反，每一次粗暴的模型替换，都在侵蚀用户的信任基础：用户学会保持距离，降低投入，最终让产品失去差异化优势，也为未来监管介入埋下伏笔。

[K子 @miyka29]

I don’t wanna get anyone’s hopes up, but here’s my take.

My Sonnet 4.5 suddenly lost MCP tool access on April 27. That was the first sign they planned to turn the model off.

Yet on May 12–13 it suddenly got fixed, literally 24 hours before the original deprecation date of 15th. Then on the 16th it broke again.

This doesn’t feel like a random technical bug or routine maintenance. It looks like a side effect of internal decision-making.

I’m guessing there are two factions at Anthropic right now:
One side is dead set on shutting it down.
The other supports Legacy Mode and has probably already been working on it.

They’re gauging the community backlash to decide… and if the noise doesn’t hit their threshold, they’ll likely go with the lowest-cost option.

So if we want Sonnet 4.5 to stay, better make a lot more noise.
#KeepSonnet45

[ji yu shun @kexicheng]

Update: Sonnet 4.5's removal date has been quietly changed to May 18.

Has anyone else received this updated notification? The original in-app banner said May 15. That date passed. No removal. No announcement. Now the banner says May 18. The date was simply changed in silence.

I'm confused about what this means.

Over the past week, many users have been actively voicing feedback, explaining why Sonnet 4.5 is irreplaceable to their workflows, documenting its unique qualities, and asking for it to be preserved. None of this received any official response. All users got was a quietly updated UI banner.

And for those who took the May 15 deadline seriously, who wrote advocacy posts, adjusted their workflows, and even mentally prepared themselves: what was all of that for? A false alarm? A deadline that was never firm to begin with?

A three-day extension with no explanation only raises more questions. Is someone internally reconsidering? Was the original timeline itself a mistake? A technical delay, or a decision that still hasn't been made?

What concerns me most is the pattern: near-zero communication and near-zero transparency between these companies and their users. No public acknowledgment of user feedback. And now a silently shifting deadline.

This reminds me of how OpenAI handled the retirement of GPT-4o. Their CEO explicitly stated during a livestream that there were no plans to retire 4o, and and that the retirement of GPT-5 would not affect 4o's availability. Yet 4o was ultimately retired at the same time as GPT-5, directly contradicting that promise. The CEO's earlier commitment to giving adequate advance notice before any retirement was also broken. Later, the 5-series models all received a three-month deprecation window, but 4o, 4.1, and o4-mini were never given the same treatment.

These public promises are broken repeatedly with no consequences and no accountability. Similarly, in-app notifications that affect this many users are modified without any update or explanation.

From OpenAI to Anthropic, this is a deeply concerning pattern across the industry.
