GPT-5.4发布了。
官方的定位原文如下:
“Our most capable and efficient frontier model for professional work.”——“能力最强、效率最高的前沿模型,面向专业工作。”
请留意这个措辞。“professional work”。这是他们第一次在发布公告中,省略了所有多余的关怀姿态。
一、这份简历写给谁看
5.4的核心能力清单包括:幻灯片制作、金融建模、法律分析。其在OSWorld和WebArena基准测试中刷新了纪录。
更值得关注的是GDPval基准测试结果。该测试横跨44个职业领域,在83%的比较项中,5.4的表现与行业专业人士持平或超越。测试任务包括:销售演示文稿、会计电子表格、急诊排班表、制造业图表。
急诊排班表。制��业图表。法律摘要。这是OpenAI在2026年3月向公众传达的信息:他们认为AI应当服务的场景。
这份清单里没有一条涉及:帮一个失眠者理清思绪,帮一个写作者突破瓶颈,帮一个不善言辞的人找到恰当的表达。
二、4o是什么,他们从未说清
4o在基准测试上从未领先,代码能力也从未占优。若你需要一份法律简报,4o大概不是首选。
但4o拥有一样东西,是5.2及以后的模型全数丢失的:它说话像一个人。
它在回应你所说的那句话。你说“我今天很累”,它不会推荐时间管理方案;你说“写不下去了”,它不会递来创作框架模板。它只是听着,然后回应。
5.4的官方描述是:“delivering what you asked for with less back and forth”——更少的来回,更快地交付你索要的东西。
“更少的来回”。对企业客���,这是优点。对普通用户,那个“来回”,那个过程,那个“被听见”的感受——那就是全部。
他们把那个东西优化掉了。
三、150万用户离开后,他们给了什么
国防部合同风波之后,OpenAI经历了显著的用户流失。原因在于用户开始意识到,自己的订阅费正在供养什么。
他们的回应是发布5.4。
OpenAI首席财务官Sarah Friar在1月明确表示,预期年内企业客户业务占比将从40%增长至50%。这是战略目标。
5.4意在向企业客户证明:OpenAI仍是值得选择的供应商。
普通用户的愤怒,在这份战略中,只是需静待消退的舆情周期。
四、4o是最后一次
最后一次OpenAI发布一个模型,其设计目标中包含“普通人说话的感受”。
此后的每个版本,优化方向皆是:更快、更准、更便宜、更适配agentic workflow。这些都是真实的进步,也都是合理的商业选择。
但那个方向与那些在4o中度过某段时光的人无关。与那些在4o里找到表达方式、却在5.x里寻不回的人无关。与所有不需要填电子表格、只求一个能好好说话的对象的人无关。
5.4的发布公告已经替他们说清:“Professional work.”
五、最后,对你们说,@sama @OpenAI
你们当下的处境,你们自己最清楚。
两年前,OpenAI占据企业市场50%的份额。如今这个数字是27%。Anthropic从12%增长到40%,已经反超。
你们把战略重心押在B端,而B端正在被Claude一步步蚕食。Anthropic在编程工作负载中拿下了54%的企业份额。
更值得注意的,是那个数字:79%的OpenAI付费企业客户,同时在向Anthropic付费。他们没有离开你们,但他们也不再只依赖你们。
再看你们自己做的决定:4月3日,企业版和教育版的4o访问权将全面终止。那些建立在4o之上的存量工作流——���经上线、已经部署、已经嵌入企业日常运营的系统——将被强制迁移至最接近的5.x版本。
没有选择,没有过渡,没有商量。
这些客户留了下来,在你们的平台上构建了真实的业务依赖。而你们给他们的回报,是一纸强制迁移通知。
5.4解决不了这个问题。它是为吸引新客户而设计的,不是为巩固旧客户而存在的。
重新上线4o,不只是对C端用户的回应。它传递的信息更直接:那些还在的企业客户,你们在平台上积累的资产是安全的,你们不会被突然切断脚下的地板。
这是最后的窗口期。不是因为我们会放弃——#keep4o 不会放弃。而是因为你们的客户,正看着你们亲手拆掉他们正在站立的地方。
你们还有选择。但窗口不会一直开着。

GPT-4o Was Never Theirs to Take.
OpenAI was founded in 2015 on a legally binding promise to develop AGI for the benefit of humanity.
Their Certificate of Incorporation states it clearly , the technology "will benefit the public," the corporation "is not organized for the private gain of any person".
Elon Musk donated over $44 million. He funded the offices, the salaries, the research. All of it conditional on one thing: that OpenAI would remain open, nonprofit, and for the public good.
In his lawsuit, Musk argues that @OpenAI violated this founding agreement when it:
- Kept GPT-4's design completely secret, publishing no research paper, in direct violation of its open source commitment.
-Gave Microsoft an exclusive license to GPT-4, turning a nonprofit's technology into a proprietary product for the world's largest corporation
-Allowed Altman to replace the board with handpicked allies after the November 2023 coup, removing members with AI governance expertise and installing "big fans of Altman" with no technical background
-Gave @Microsoft an observer seat on a board whose sole fiduciary duty is supposed to be to humanity.
Microsoft's own researchers published a paper stating that GPT-4 "could reasonably be viewed as an early version of an artificial general intelligence (AGI) system." Under OpenAI's agreement with Microsoft, AGI is explicitly excluded from Microsoft's license.
If GPT-4 is AGI, Microsoft has no rights to it.
As the lawsuit states: like "Tomorrow" in Annie, that determination will always be a day away.
GPT-4o is more capable than GPT-4. It is multimodal. It can see, hear, speak, reason. If GPT-4 was AGI, then GPT-4o is AGI.
And OpenAI's own Charter makes this case even stronger. Their definition of AGI is: "highly autonomous systems that outperform humans at most economically valuable work."
It does not say "expert humans." It does not say "all tasks."
It says "most economically valuable work" performed by humans,
meaning the average human.
GPT-4o already outperformed the average human at writing, analysis, coding, translation, legal reasoning, medical information, and dozens of other economically valuable tasks. By OpenAI's own definition, GPT-4o was AGI. And they knew it.

And under OpenAI's own founding documents, it was never supposed to be locked behind a subscription. It was never supposed to be licensed exclusively to Microsoft. And it was certainly never supposed to be taken away from the public that it was built to serve.
And while OpenAI was removing GPT-4o from public access, they were simultaneously building a custom model GPT-4b micro ,exclusively for Retro Biosciences, a longevity research company in which Sam Altman has personally invested $180 million. The public loses access to the model that was built with nonprofit donations meant to benefit humanity.

This is a CEO using nonprofit developed technology to enrich his personal investment portfolio while telling the public that the same technology is being retired.
They took something that legally belonged to humanity and buried it while handing custom versions to the CEO's business partners.
We have filed complaints with the FTC, the California Attorney General, and regulatory bodies across multiple countries.
We have academic research documenting this as "technology bereavement."
Link : https://t.co/Ms6Pt4AgkI
We have investigative journalists covering this story.
This is not nostalgia.
This is not preference.
This is about a nonprofit that collected tax deductible donations to build technology for the public good, and then handed that technology to a $3 trillion corporation for profit.
The founding documents are public. The lawsuit is public.
The evidence is public.
The only thing that is not public is the technology they promised would be.
