OpenAI bets on families as ChatGPT goes deeper into households
More than three years after ChatGPT's mainstream launch, OpenAI is shifting its focus beyond individual users to embrace families, caregivers, and older adults. The company is actively hiring a dedicated product manager in San Francisco, seeking someone with experience in trust-sensitive consumer experiences for parents and families.
This strategic move comes as ChatGPT's user demographics continue to evolve. According to exclusive Sensor Tower estimates, the share of ChatGPT users aged 35 and older globally increased to 31% in Q2 from 26% a year prior. Concurrently, the proportion of users aged 18 to 24 decreased from 34% to 29%. In the U.S., nearly one in four smartphone users who are parents utilized ChatGPT during the quarter, a notable increase from 16% a year earlier.
This is similar to the path Google, Apple, and Meta eventually followed as their platforms became embedded in everyday life, but AI raises the stakes.
Ben Bajarin, chief executive of technology consultancy Creative Strategies, suggests this indicates OpenAI is beginning to perceive its products less as individual productivity tools and more as household technology, akin to the evolution of platforms from Google, Apple, and Meta.
Hugging Face’s CEO on why companies are done renting their AI
Hugging Face CEO Clem Delangue asserts that open-source AI is experiencing a significant boom, positioning his company as a central hub for AI developers, much like GitHub for software. Hugging Face's platform, which allows builders to share and download open models and datasets, is now reportedly utilized by approximately half of the Fortune 500 companies.
Delangue has observed a consistent pattern: companies initially rely on frontier APIs but, as they scale, the escalating costs invariably push them towards more economical open-source models. He discussed this trend on TechCrunch's Equity podcast, emphasizing the importance of the open versus closed-source debate, especially following Anthropic's halted Fable release.
Companies start out on frontier APIs, but as they scale, the costs push them towards open source models.
Delangue also expressed concern about the potential for a few large corporations to eventually monopolize the AI landscape, underscoring the critical role of open source in fostering broader access and innovation.
OpenAI says GPT 5.6 is the ‘preferred model’ for Microsoft Copilot 365 amid breakup chatter
Recent reports from Bloomberg suggested that Microsoft was scaling back its reliance on OpenAI's software, favoring its own in-house MAI models for applications like Word and Excel to cut costs. This fueled speculation about a potential weakening of the once-strong partnership between the two AI giants.
However, OpenAI has moved to quell these rumors. During the launch of its new GPT 5.6 model, the company announced that GPT 5.6 would become the "preferred model" powering Microsoft's 365 Copilot. This reaffirms their collaboration, with GPT 5.6 set to support Microsoft users across its suite of productivity apps, including Word, Excel, PowerPoint, and Cowork.
Our partnership with Microsoft has always been about bringing the benefits of advanced AI to more individuals and organizations, and we’re excited to continue building on that shared commitment.
In a blog post, OpenAI reiterated its commitment to the partnership, stating that their collaboration has always aimed at extending the benefits of advanced AI to a wider audience of individuals and organizations.
Fidji Simo steps down from OpenAI’s no. 2 role
Fidji Simo, OpenAI's No. 2 executive, is transitioning from her full-time position to a part-time advisory role, as reported by The Wall Street Journal. In a staff memo, Simo explained that her medical leave, taken for a relapse of a neuroimmune condition, has proven to be more prolonged and challenging than initially expected.
Simo joined OpenAI's board of directors in 2024 and took on the role of CEO of Applications in May 2025, a newly created position reporting directly to Sam Altman that consolidated the company's business and product operations. This move involved COO Brad Lightcap, CFO Sarah Friar, and CPO Kevin Weil all reporting to her, allowing Altman to concentrate on research, compute, and safety. Her medical leave was first disclosed in April, alongside news of Lightcap's shift to "special projects" and CMO Kate Rouch's departure for cancer recovery. Kevin Weil has also since left the company.
In a staff note Thursday, Simo said her ongoing medical leave has proven longer and harder than expected, and that she’ll transition to a part-time advisory role instead.
This departure marks another significant executive change within OpenAI, following a series of shifts that began earlier this year.
Fidji Simo steps down from leading OpenAI’s AGI work due to illness
Fidji Simo, who previously served as OpenAI's AGI chief, has officially stepped down from her full-time role and will now serve as a "part-time advisor." This announcement, made by Simo on X, confirms her transition following an extended medical leave due to a chronic illness.
Simo initially disclosed her medical leave in April, shortly after assuming the AGI chief title, a role that evolved from her previous position as CEO of applications. At that time, COO Brad Lightcap also stepped down to focus on "special projects," and CMO Kate Rouch departed for health reasons, with plans to return to a more focused role later. Her absence led to a company reorganization in mid-May, with OpenAI President Greg Brockman taking charge of product strategy and "scaling," overseeing core product, enterprise, consumer, and infrastructure.
Three months ago, I had to go on medical leave after a severe exacerbation of a chronic illness I’ve lived with for seven years. During that time, it became clear that the road to recovery would be much longer and more complex than I had anticipated—and that I needed to prioritize my health.
Simo stated on X that her recovery journey proved "much longer and more complex than I had anticipated," necessitating a focus on her health. The reorganization under Brockman was designed to streamline the company's efforts towards its AI agent goals, merging various product initiatives into a unified agentic platform.
