Finally, I enjoyed hearing Dayle Stevens from Telstra explain why her company chose to form a joint venture with Accenture to deliver its AI stragegy, rather than simply hiring the consulting firm under a traditional service contract. Stevens said the joint venture has enabled the company to move much faster than it would have otherwise and to tap expertise, including starting an AI innovation hub in Silicon Valley, that would have been hard to implement otherwise. 

The future of enterprise AI is hybrid

Now, here’s Sharon’s takeaways: In my mainstage session with PayPal global head of AI Prakhar Mehrotra and Marc Hamilton, VP of solutions architecture and engineering at Nvidia, both discussed the increasing power of open source AI models to allow enterprise companies to control their data and fine-tune for specific use cases. But both agreed that the future of enterprise AI will be hybrid, with enterprises typically using both open models and proprietary model APIs.

There was plenty of time for philosophizing, as well: at one dinner, I chatted with delegates from The Clorox Company, Workday and other companies about everything from what jobs were future-proof (I suggested dog walkers were safe from AI) to what AI would really mean for the future of today’s children (the bottom line: they still need to learn to think for themselves!).

My favorite panel was one I moderated with a half-dozen leaders and stakeholders in the world of AI data centers, including Andy Hock from Cerebras, Matt Field from Crusoe, and former OpenAI infrastructure policy leader Lane Dilg. We dug into how the line is blurring between power infrastructure and data centers, with billions in capital and gigawatts of power at play. My biggest takeaway was that the AI data center issue is local, local, local. Every community and local government will be dealing with its own specific issues and compromises around issues such as land, energy, and water—and what works for one area might not work for another.

People and culture are paramount

And here is what Bea had to say about this year’s Brainstorm AI San Francisco:

Most enterprises are still trying to figure out the best way to adopt AI, but leaders this year were also keen to emphasize that choosing the right tools is only part of the equation. Companies also need to ensure that both their employees and their org charts are ready for the shift—otherwise, even the most advanced AI pilots are likely to fail.

As Accenture’s Chief Responsible AI Officer Arnab Chakraborty put it: “Don’t just think about technology—think about people and the culture. It is so paramount.”

Or take Open Machine CEO Allie K. Miller’s advice and don’t call AI a tool at all: “Calling it a tool ends up being a little bit of borderline self-limiting behavior that is holding enterprise all around the world behind.”

I also moderated a panel of healthcare experts, which brought together a mix of clinicians who see patients every day and tech leaders building and deploying healthtech tools at scale. In healthcare, the industry is generally feeling good about clinician-facing AI, but it’s still wrestling with what it means to safely deploy patient-facing agents.

The panelists discussed, among other things, what it means to be moving toward a future where patients and clinicians consult the same AI before they consult each other.

The excitement is running high on the corporate side, but not that much has really changed in the examination room—at least according to Gurpreet Dhaliwal, a clinician-educator and Professor of Medicine at the University of California. Whether it’s with Dr. Google, Dr. ChatGPT, or just a neighbor with some strong beliefs about antibiotics, Dhaliwal said patients have always arrived with a second opinion in their back pocket. While AI is poised to be a revolutionary force for healthcare—especially in fringe cases such as rare diseases—it’s yet to fundamentally change the dynamic between patients and their physicians.

With that, here’s the rest of the AI news.

AI IN THE NEWS

Disney invests $1 billion in OpenAI, brings characters to OpenAI apps. The home of Mickey Mouse is investing $1 billion in OpenAI and, under a three-year licensing deal, will let users generate short, prompt-driven videos in OpenAI’s Sora app using more than 200 Disney, Marvel, Star Wars, and Pixar characters. OpenAI is supposed to create guardrails to prevent users from creating videos or images that might reflect poorly on the Disney brand. The partnership was struck after nearly two years of talks. Meanwhile, Disney simultaneously sent a cease-and-desist letter to Google accusing it of large-scale copyright infringement tied to AI outputs featuring Disney characters.

OpenAI debuts GPT-5.2 model, answering concerns it was trailing competitors. The company launched a new AI model that, according to evaluations OpenAI conducted, delivers state-of-the-art performance across a wide range of tasks, including coding, mathematical reasoning, and “knowledge work.” The model showed significant improvement over GPT-5.1, which OpenAI released only a month ago, and bested Google’s and Anthropic’s new models. The release of Google’s Gemini 3 Pro in late November prompted OpenAI CEO Sam Altman to declare a “code red” to refocus the company on improving ChatGPT. But OpenAI executives said the release of GPT-5.2 had been in the works for months and that its debut was not related to the “code red.” OpenAI said GPT-5.2 also improves safety, particularly around mental health–related responses.

New lawsuit claims ChatGPT contributed to murder-suicide in Connecticut. A wrongful-death lawsuit was filed against OpenAI and Microsoft after a 56-year-old Connecticut man, Stein-Erik Soelberg, killed his 83-year-old mother and then himself following months of increasingly delusional conversations with ChatGPT. His family says the chatbot reinforced and contributed to his mental illness. OpenAI has expressed condolences and pointed to ongoing improvements to ChatGPT’s ability to recognize and respond to users in distress. You can read more from The Wall Street Journal here.

Microsoft says health queries are the most frequent use of its Copilot AI by consumers. Microsoft analyzed 37.5 million anonymized Copilot conversations from January through September 2025 to understand how people use the AI assistant in daily life. The study found that health-related questions dominated mobile usage, while topics and usage patterns varied significantly by device, time of day, and context. Beyond information search, users increasingly turned to Copilot for advice on personal topics, showing its role as a companion in both work and life moments.

Meta and Eleven Labs sign a new partnership to provide voice overs for Reels. Meta has partnered with London-based voice AI company ElevenLabs to integrate AI-powered audio capabilities across Instagram and Horizon. This partnership will enable new features such as the ability to dub Reels into local languages as well as to generate character voices. You can read more in The Economic Times here.
