What we still don’t know about weight-loss drugs
Weight-loss drugs have been back in the news this week. First, we heard that Eli Lilly, the company behind Mounjaro and Zepbound, became the first healthcare company in the world to achieve a trillion-dollar valuation.
But we also learned that, disappointingly, GLP-1 drugs don’t seem to help people with Alzheimer’s disease. And that people who stop taking the drugs when they become pregnant can experience potentially dangerous levels of weight gain. On top of that, some researchers worry that people are using the drugs postpartum to lose pregnancy weight without understanding potential risks.
All of this news should serve as a reminder that there’s a lot we still don’t know about these drugs. So let’s look at the enduring questions surrounding GLP-1 agonist drugs.

If you’re interested in weight loss drugs and how they affect us, take a look at:
+ GLP-1 agonists like Wegovy, Ozempic, and Mounjaro might benefit heart and brain health—but research suggests they might also cause pregnancy complications and harm some users. Read the full story.
+ We’ve never understood how hunger works. That might be about to change. Read the full story.
+ Weight-loss injections have taken over the internet. But what does this mean for people IRL?

What we know about how AI is affecting the economy
There’s a lot at stake when it comes to understanding how AI is changing the economy right now. Should we be pessimistic? Optimistic? Or is the situation too nuanced for that?
Hopefully, we can point you towards some answers. Mat Honan, our editor in chief, will hold a special subscriber-only Roundtables conversation with our editor at large David Rotman, and Richard Waters, Financial Times columnist, exploring what’s happening across different markets. Register here to join us at 1pm ET on Tuesday December 9.
The event is part of the Financial Times and MIT Technology Review “The State of AI” partnership, exploring the global impact of artificial intelligence. Over the past month, we’ve been running discussions between our journalists—sign up here to receive future editions every Monday.

One more thing
How to build a better AI benchmark
It’s not easy being one of Silicon Valley’s favorite benchmarks.
SWE-Bench (pronounced “swee bench”) launched in November 2024 as a way to evaluate an AI model’s coding skill. It has since quickly become one of the most popular tests in AI. A SWE-Bench score has become a mainstay of major model releases from OpenAI, Anthropic, and Google—and outside of foundation models, the fine-tuners at AI firms are in constant competition to see who can rise above the pack.
Despite all the fervor, this isn’t exactly a truthful assessment of which model is “better.” Entrants have begun to game the system—which is pushing many others to wonder whether there’s a better way to actually measure AI achievement. Read the full story.
