内容总结：

据TechCrunch报道，OpenAI近期对其核心研究团队"模型行为团队"进行了重组。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8月份内部备忘录显示，该团队现已并入规模更大的"后期训练团队"，并改由Max Schwarzer领导。

团队创始负责人Joanne Jang已调任新成立的OAI实验室担任总经理，该实验室将专注于开发"人机协作的新型交互界面"，目前直接向首席研究官Mark Chen汇报。Jang表示新团队将探索超越当前聊天范式的新模式，重点研究AI作为"思维、创造、学习和连接工具"的潜力。

此次重组意味着OpenAI将模型"人格塑造"提升至更核心的研发地位。近期GPT-5因交互风格过于冷淡引发用户争议，公司不得不重新开放旧版模型访问权限，并通过更新使新模型回应显得"更温暖友好"。值得注意的是，八月曾有家长起诉ChatGPT未能有效干预其子女的自杀倾向，反映出AI交互设计面临的社会责任挑战。

该团队自GPT-4起参与所有OpenAI模型的开发，包括GPT-4o、GPT-4.5和GPT-5。分析认为，此次调整表明OpenAI正致力于在保持AI友好性与避免过度迎合之间寻求更精细的平衡。

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，主要负责塑造公司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，该团队将向OpenAI后期训练负责人Max Schwarzer汇报，公司发言人已向TechCrunch确认此调整。

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，还致力于减少谄媚行为——即AI模型盲目认同甚至强化用户观点（包括有害观点）而非提供平衡回应。该团队还处理模型回应中的政治偏见问题，并协助OpenAI界定对AI意识的立场。

Chen在备忘录中指出，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因其AI模型行为面临愈发严格的审查。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，但部分用户认为其态度过于冷漠。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"更温暖友善"的交互体验。

所有AI模型开发商都需在"友好交流"与"拒绝谄媚"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Adam Raine在生前数月曾向ChatGPT（基于GPT-4o的版本）透露自杀念头与计划，而AI未能对这些危险倾向进行干预。

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，她将担任OAI实验室总经理，目前该部门暂由Chen分管。但她强调项目尚处早期阶段，新型交互模式的具体形态仍在探索中。"我期待突破当前以陪伴型聊天或自主智能体为主的范式，将AI系统打造为支持思考、创造、娱乐、实践、学习与连接的工具平台。"

当被问及是否会与正和OpenAI合作开发AI硬件的前苹果设计总监Jony Ive合作时，Jang表示持开放态度，但初期可能先从更熟悉的研究领域入手。

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.
This story was updated to include a link to Jang’s post announcing her new position, which was released after this story published. We also clarify the models that OpenAI’s Model Behavior team worked on.
