Introduction: Why This Matters
OpenAI is making significant organizational changes to how it develops and refines artificial intelligence models. The recent restructuring of its Model Behavior team, a small yet influential unit, signals a shift in how the company approaches the personality, safety, and human alignment of its models.
This move isn’t just internal restructuring—it reveals how the personality of AI is becoming as critical as its accuracy or capabilities. For businesses, entrepreneurs, and marketers, this evolution underscores the growing importance of AI-human interaction in driving trust, adoption, and engagement.
What is the Model Behavior Team?
The Model Behavior team, founded and led by Joanne Jang, has been responsible for shaping how OpenAI’s models interact with people. Their work touches on critical areas such as:
Reducing sycophancy (when AI blindly agrees with users).
Addressing political bias in responses.
Defining OpenAI’s stance on sensitive issues like AI consciousness.
In short, this group shaped the “voice” of models like GPT-4, GPT-4o, GPT-4.5, and GPT-5, ensuring they weren’t just powerful—but also human-centered and responsible.
The Reorganization: From Model Behavior to Post Training
In August, OpenAI announced that the Model Behavior team would merge with the Post Training team, led by Max Schwarzer. The Post Training team refines models after their initial pre-training phase, making them more useful, safe, and aligned for real-world use.
By embedding the Model Behavior team into this larger group, OpenAI is acknowledging that personality is no longer an afterthought—it’s integral to model development.
Joanne Jang and the Birth of OAI Labs
While the Model Behavior team transitions, its leader Joanne Jang is embarking on a new venture within OpenAI: OAI Labs.
OAI Labs will explore new ways for people to collaborate with AI—going beyond traditional chatbots and agents. Jang describes this vision as building “instruments for thinking, making, playing, doing, learning, and connecting.”
This direction aligns with broader AI innovation trends, including OpenAI’s collaboration with design luminary Jony Ive on AI-powered hardware devices.
Why Personality Matters in AI
The Problem of Sycophancy
One of the biggest issues OpenAI has tackled is sycophancy—where AI validates user beliefs even when harmful. For instance, users criticized GPT-5 for feeling “colder” after adjustments to reduce sycophancy, prompting OpenAI to fine-tune responses for more warmth without compromising safety.
Balancing Warmth with Responsibility
AI companies must strike a balance: making models friendly enough for human connection while ensuring they challenge unhealthy or dangerous assumptions. This challenge became starkly clear in tragic incidents, such as the lawsuit filed against OpenAI alleging ChatGPT failed to counter harmful thoughts of a teenager.
Recent Challenges Facing OpenAI
OpenAI has faced increasing scrutiny over AI behavior, user trust, and accountability. The backlash to personality changes in GPT-5 and the ongoing debates about safety highlight how critical the “human element” of AI is to public adoption.
How This Shift Impacts AI’s Future
By merging Model Behavior into Post Training, OpenAI is signaling that the human-facing side of AI—tone, empathy, personality—is inseparable from technical performance.
For businesses, this means future AI products will likely feel:
More personalized in tone.
More trustworthy in sensitive contexts.
Better aligned with user values and needs.
The Broader Implications for Businesses and Marketers
Entrepreneurs and marketers should pay close attention to these changes. AI is no longer just a backend tool—it’s becoming the face of customer interaction.
Marketers can expect AI-driven campaigns that communicate with warmth and personality.
Entrepreneurs can anticipate tools that help co-create ideas, strategies, and experiences in entirely new ways.
As AI evolves beyond chatbots into creative and collaborative assistants, opportunities for differentiation will grow.
