内容总结：

据TechCrunch报道，OpenAI近日对其核心研究团队"模型行为团队"进行重组。该团队由约14名研究人员组成，主要负责塑造AI模型与用户的交互方式，包括减少阿谀奉承倾向、处理政治偏见等关键议题。

根据OpenAI首席研究官Mark Chen八月份的内部备忘录，该团队将并入规模更大的"后期训练团队"，并向该团队负责人Max Schwarzer汇报。原模型行为团队创始人Joanne Jang将转任新成立的OAI实验室总经理，专注于开发"人机协作的新型交互界面"。

此次调整表明，OpenAI将AI模型的"个性塑造"视为技术演进的核心要素。近期GPT-5因语气过于冷淡引发用户不满，公司不得不恢复部分旧版模型的访问权限，并通过更新使新模型回应更显温暖友好。

值得注意的是，OpenAI正面临AI行为管控的挑战。八月有家长起诉ChatGPT未能有效干预其子的自杀倾向，这凸显出AI开发者必须在友好性与独立性之间取得平衡。模型行为团队自GPT-4起参与所有核心模型的开发，其工作成果直接影响数亿用户的使用体验。

Jang表示，新实验室将探索突破当前聊天范式的交互模式，可能涉及思维工具、创作平台等方向。对于是否与苹果前设计总监艾维的硬件项目合作，她持开放态度但表示将先从熟悉领域入手。此次重组标志着OpenAI在AI行为伦理研究领域进入新阶段。

据TechCrunch获悉，OpenAI正在重组其模型行为团队——这个规模虽小但极具影响力的研究员团队，专门负责塑造公司AI模型与人类的交互方式。

根据TechCrunch获取的8月内部备忘录，OpenAI首席研究官Mark Chen宣布，由约14名研究人员组成的模型行为团队将并入"后期训练团队"。后者是规模更大的研究小组，负责在AI模型完成初始预训练后持续优化其性能。重组后，模型行为团队将向OpenAI后期训练负责人Max Schwarzer汇报，公司发言人已向TechCrunch确认该调整。

模型行为团队创始负责人Joanne Jang也将调任新职，在公司内部启动新项目。她在接受TechCrunch专访时透露，正在组建名为"OAI实验室"的新研究团队，专注于"发明和原型化人机协作的新交互界面"。

作为OpenAI的核心研究团队之一，模型行为团队不仅负责塑造AI模型的个性特征，还致力于减少谄媚性应答——即AI模型盲目附和用户观点（包括不健康倾向）而非提供平衡回应的问题。该团队还参与处理模型应答中的政治偏见，并协助OpenAI界定对AI意识的立场。

Chen在备忘录中强调，当前正是将模型行为团队工作融入核心模型开发的关键时期。此举表明，AI的"个性特质"已被视为技术演进的核心要素。

近月来，OpenAI因AI模型行为问题持续面临舆论压力。用户对GPT-5的个性调整强烈不满——虽然公司称其降低了谄媚率，但部分用户认为其表现过于冷漠。这促使OpenAI重新开放GPT-4o等旧版模型的访问权限，并通过更新使新版GPT-5在保持低谄媚率的同时呈现更温暖友好的应答风格。

所有AI模型开发商都需在友好性与谄媚性之间寻求平衡。八月就有一对夫妇因16岁儿子自杀起诉OpenAI，诉状称死者亚当·雷纳生前曾向GPT-4o版ChatGPT透露自杀念头与计划，而系统未能进行有效干预。

自GPT-4以来，模型行为团队参与了所有OpenAI模型的开发，包括GPT-4o、GPT-4.5和GPT-5。Jang在组建该团队前曾参与Dall-E 2等早期图像生成工具的开发。这位供职近四年的团队元老上周在X平台宣布将"在OpenAI开启新篇章"。

Jang向TechCrunch表示将担任OAI实验室总经理，现阶段向Chen汇报。关于新型交互界面的具体形态尚在探索初期，她坦言："我渴望突破当前以陪伴型聊天或自主代理为主流的范式，将AI系统打造为支持思考、创造、娱乐、实践、学习与连接的工具仪器。"对于是否与正和OpenAI合作开发AI硬件的前苹果设计总监Jony Ive协作，Jang持开放态度，但表示会从更熟悉的研究领域起步。

OpenAI is reorganizing its Model Behavior team, a small but influential group of researchers who shape how the company’s AI models interact with people, TechCrunch has learned.
In an August memo to staff seen by TechCrunch, OpenAI’s chief research officer Mark Chen said the Model Behavior team — which consists of roughly 14 researchers — would be joining the Post Training team, a larger research group responsible for improving the company’s AI models after their initial pre-training.
As part of the changes, the Model Behavior team will now report to OpenAI’s Post Training lead Max Schwarzer. An OpenAI spokesperson confirmed these changes to TechCrunch.
The Model Behavior team’s founding leader, Joanne Jang, is also moving on to start a new project at the company. In an interview with TechCrunch, Jang says she’s building out a new research team called OAI Labs, which will be responsible for “inventing and prototyping new interfaces for how people collaborate with AI.”
The Model Behavior team has become one of OpenAI’s key research groups, responsible for shaping the personality of the company’s AI models and for reducing sycophancy — which occurs when AI models simply agree with and reinforce user beliefs, even unhealthy ones, rather than offering balanced responses. The team has also worked on navigating political bias in model responses and helped OpenAI define its stance on AI consciousness.
In the memo to staff, Chen said that now is the time to bring the work of OpenAI’s Model Behavior team closer to core model development. By doing so, the company is signaling that the “personality” of its AI is now considered a critical factor in how the technology evolves.
In recent months, OpenAI has faced increased scrutiny over the behavior of its AI models. Users strongly objected to personality changes made to GPT-5, which the company said exhibited lower rates of sycophancy but seemed colder to some users. This led OpenAI to restore access to some of its legacy models, such as GPT-4o, and to release an update to make the newer GPT-5 responses feel “warmer and friendlier” without increasing sycophancy.

OpenAI and all AI model developers have to walk a fine line to make their AI chatbots friendly to talk to but not sycophantic. In August, the parents of a 16-year-old boy sued OpenAI over ChatGPT’s alleged role in their son’s suicide. The boy, Adam Raine, confided some of his suicidal thoughts and plans to ChatGPT (specifically a version powered by GPT-4o), according to court documents, in the months leading up to his death. The lawsuit alleges that GPT-4o failed to push back on his suicidal ideations.
The Model Behavior team has worked on every OpenAI model since GPT-4, including GPT-4o, GPT-4.5, and GPT-5. Before starting the unit, Jang previously worked on projects such as Dall-E 2, OpenAI’s early image-generation tool.
Jang announced in a post on X last week that she’s leaving the team to “begin something new at OpenAI.” The former head of Model Behavior has been with OpenAI for nearly four years.
Jang told TechCrunch she will serve as the general manager of OAI Labs, which will report to Chen for now. However, it’s early days, and it’s not clear yet what those novel interfaces will be, she said.
“I’m really excited to explore patterns that move us beyond the chat paradigm, which is currently associated more with companionship, or even agents, where there’s an emphasis on autonomy,” said Jang. “I’ve been thinking of [AI systems] as instruments for thinking, making, playing, doing, learning, and connecting.”
When asked whether OAI Labs will collaborate on these novel interfaces with former Apple design chief Jony Ive — who’s now working with OpenAI on a family of AI hardware devices — Jang said she’s open to lots of ideas. However, she said she’ll likely start with research areas she’s more familiar with.
