The Download: generative AI's carbon footprint, and a CRISPR patent battle

The significance: These emissions will add up quickly. The generative-AI boom has led big tech companies to integrate powerful AI models into many different products, from email to word processing. They are now used millions, if not billions, of times every single day. The bigger picture: The study shows that while training massive AI models is incredibly energy intensive, it's only one part of the puzzle. Most of their carbon footprint comes from their actual use.
