On Monday, the stock market went into a tizzy over a new AI model from Chinese company DeepSeek. It seemed to be just as powerful as many of its American competitors, but its makers claimed to have made it far more cheaply, using far less computing power than similar AI apps like ChatGPT, Claude, or Gemini. In one day, hundreds of billions of dollars were wiped off the valuations of companies related to AI.This week, investors seemed suddenly to change their minds about what our AI future would look like and which companies will (or won't) profit from it. Will we really need all those high-end computer chips, after all? What about power plants to provide electricity for all the energy-hungry AI data centers? On today's show – how DeepSeek might have changed the economics of artificial intelligence forever.This episode was produced by Willa Rubin with an assist from James Sneed.

When it comes to solar and wind power, renewable energy has always had a caveat: it can only run when the wind blows or the sun shines.The idea of a battery was floated around to make renewables available 24/7. For years, it existed as an expensive, little-used technology. Then in 2021, it took off.In this episode, we explore how this new energy market works in two states: California and Texas.In California, there is now enough grid-scale battery storage to power millions of homes — at least for a few hours — and it's growing fast. What does this success mean for the grid, and how did the state support it?Then, we visit Texas, whose approach is more free-market rodeo. The state has the second-most battery storage capacity in the U.S. And in Texas, their system was recently put to the test. So, can these large-scale batteries can help prevent blackouts?These two stories come from our sister show The Indicator, which recently reported a series about the electric battery market.Today's show was hosted by Cooper Katz McKim, Darian Woods and Wailin Wong. The original Indicator episodes were produced by Cooper Katz McKim and Corey Bridges, and edited by Kate Concannon.

The city is expecting immigration raids, detentions and deportations. In the Little Village neighborhood, where the majority of residents are Mexican or of Mexican descent, people are on edge as they await what's next.Beyond the many people personally affected, past research suggests everyone could feel the impacts of mass deportation.On this episode of Planet Money we visit Little Village to see how the new administration is already having an impact. And then, we hear from an economist who looks to a recent chapter in mass deportation for insight into what the future could hold.Today's episode was hosted by Erika Beras and Amanda Aronczyk.
