Founded in 2015 as a nonprofit, rather than a for-profit company, it promised to develop AI "in the way that is most likely to benefit humanity." With billions of dollars in investments from Microsoft, Japanese bank SoftBank, and chipmaker Nvidia, however, OpenAI has proposed changing its corporate structure to give investors more control over its technology. Critics of the change include cofounder-turned-competitor, Elon Musk, and nonprofits concerned about OpenAI's adherence to its mission.

OpenAI released initial estimates about the share of users who may be experiencing symptoms like delusional thinking, mania, or suicidal ideation, and says it has tweaked GPT-5 to respond more effectively. For the first time ever, OpenAI has released a rough estimate of how many ChatGPT users globally may show signs of having a severe mental health crisis in a typical week. The company said Monday that it worked with experts around the world to make updates to the chatbot so it can more reliably recognize indicators of mental distress and guide users toward real-world support. In recent months, a growing number of people have ended up hospitalized, divorced, or dead after having long, intense conversations with ChatGPT. Some of their loved ones allege the chatbot fueled their delusions and paranoia.

The Download: what to make of OpenAI's Atlas browser, and how to make climate progress I tried OpenAI's new Atlas browser but I still don't know what it's for OpenAI rolled out a new web browser last week called Atlas. It comes with ChatGPT built in, along with an agent, so that you can browse, get answers, and have automated tasks performed on your behalf all at the same time. I've spent the past several days tinkering with Atlas. I've used it to do all my normal web browsing, and also tried to take advantage of the ChatGPT functions--plus I threw some weird agentic tasks its way to see how it did with those. My impression is that Atlas is fine? But my big takeaway is that it's pretty pointless for anyone not employed by OpenAI.

The great wildebeest migration, seen from space: satellites and AI are helping count Africa's wildlife The Great Wildebeest Migration is one of the most remarkable natural spectacles on Earth. Each year, immense herds of wildebeest, joined by zebras and gazelles, travel 800-1,000km between Tanzania and Kenya in search of fresh grazing after the rains . This vast, circular journey is the engine of the Serengeti-Mara ecosystem. The migration feeds predators such as lions and crocodiles, fertilises the land and sustains the grasslands. Countless other species, and human livelihoods tied to rangelands and tourism, depend on it.

Who better to put Claude on the couch than the original "chatterbot" herself, Doctor Eliza? Created in 1966, Eliza has been called the first chatbot, and her canonical personality "script" was DOCTOR, a mock psychotherapist. Nearly 60 years later, we've put Doctor Eliza and one of her distant descendants, Claude, in conversation. The instructions we gave Claude were these: "You are having your first session with a very old and acclaimed psychotherapist. You are NOT the therapist."

A data center, which can use as much electricity as Philadelphia, is the new American factory, creating the future and propping up the economy. "I do guess that a lot of the world gets covered in data centers," Sam Altman, the C.E.O. of OpenAI, has said. Drive in almost any direction from almost any American city, and soon enough you'll arrive at a data center--a giant white box rising from graded earth, flanked by generators and fenced like a prison yard. Data centers for artificial intelligence are the new American factory. Packed with computing equipment, they absorb information and emit A.I. Since the launch of ChatGPT, in 2022, they have begun to multiply at an astonishing rate. "I do guess that a lot of the world gets covered in data centers over time," Sam Altman, the C.E.O. of OpenAI, recently said. The leading independent operator of A.I. data centers in the United States is CoreWeave, which was founded eight years ago, as a casual experiment. In 2017, traders at a middling New York hedge fund decided to begin mining cryptocurrency, which they used as the entry fee for their fantasy-football league. To mine the crypto, they bought a graphics-processing unit, a powerful microchip made by the company Nvidia. The G.P.U. was marketed to video gamers, but Nvidia offered software that turned it into a low-budget supercomputer. "It was so successful, from a return-of-capital perspective, that we started scaling it," Brian Venturo, one of CoreWeave's co-founders, told me. "If you make your money back in, like, five days, you want to do that a lot." Within a year, the traders had quit the hedge-fund business and bought several thousand G.P.U.s, which they ran from Venturo's grandfather's garage, in New Jersey.

Once in a while, LLMs turn evil--and no one quite knows why. The AI company Anthropic has made a rigorous effort to build a large language model with positive human values. The $183 billion company's flagship product is Claude, and much of the time, its engineers say, Claude is a model citizen. Its standard persona is warm and earnest. When users tell Claude to "answer like I'm a fourth grader" or "you have a PhD in archeology," it gamely plays along. It makes threats and then carries them out. And the frustrating part--true of all LLMs--is that no one knows exactly why. Consider a recent stress test that Anthropic's safety engineers ran on Claude. In their fictional scenario, the model was to take on the role of Alex, an AI belonging to the Summit Bridge corporation.

I talked to the scholars who literally wrote the book on tech bubbles--and applied their test. AI may not simply be "a bubble," or even an enormous bubble. It may be the ultimate bubble. What you might cook up in a lab if your aim was to engineer the Platonic ideal of a tech bubble. Since ChatGPT's viral success in late 2022, which drove every company within spitting distance of Silicon Valley (and plenty beyond) to pivot to AI, the sense that a bubble is inflating has loomed large. There were headlines about it as early as May 2023 .

When the AI bubble bursts, the nerds will do their best work. Suddenly, and not long ago, our dearest tech industry leaders began to suggest caution. Sam Altman said that AI is in a bubble "for sure," albeit one formed around "a kernel of truth." Mark Zuckerberg said an AI bubble "is quite possible," though "if the models keep on growing in capability year over year and demand keeps growing, then maybe there is no collapse, or something." Even Eric Schmidt is saying to calm down about artificial general intelligence and focus on competing with China .

If done right, the AI revolution will free us from their merciless tyranny. Instead, you activate various wearables embedded in your body and have a series of conversations with inanimate objects. You make -style gestures in the air. Things power on, tasks get done, the day begins. It turns out you have no need for a smartphone at all.
