This is today's edition ofThe Download,our weekday newsletter that provides a daily dose of what's going on in the world of technology. How OpenAI stress-tests its large language models OpenAI has lifted the lid (just a crack) on its safety-testing processes. It has put out two papers describing how it stress-tests its powerful large language models to try to identify potential harmful or otherwise unwanted behavior, an approach known as red-teaming. The first paper describes how OpenAI directs an extensive network of human testers outside the company to vet the behavior of its models before they are released. The second presents a new way to automate parts of the testing process, using a large language model like GPT-4 to come up with novel ways to bypass its own guardrails. MIT Technology Review got an exclusive preview of the work. Will Douglas Heaven Who should get a uterus transplant? Experts arent sure. Over 135 uterus transplants have been performed globally in the last decade, resulting in the births of over 50 healthy babies. The surgery has had profound consequences for these familiesthe recipients would not have been able to experience pregnancy any other way. But legal and ethical questions continue to surround the procedure, which is still considered experimental. Who should be offered a uterus transplant? Could the procedure ever be offered to transgender women? And if so, who should pay for these surgeries?Read the full story.

What if climate change proceeds as expected, or gets significantly worse? Could we quickly come up with the materials well need to cheaply capture carbon, or make batteries from something other than costly lithium? Materials discoverythe science of creating and developing useful new substancesoften moves at a frustratingly slow pace. The typical trial-and-error approach takes an average of two decades, making it too expensive and risky for most companies to pursue. Aspuru-Guziks objectivewhich he shares with a growing number of computer-savvy chemistsis to shrink that interval to a matter of months or years. And advances in AI, robotics, and computing are bringing new life to his vision.Read the full story.
