This week, we break down the arguments about open-weight models unfolding in Silicon Valley right now. Nvidia released an open letter signed by over 230 companies opposing “premature restrictions,” but will the Trump administration listen? Then, we’re joined by the author Claire Stapleton to discuss her new book about what she learned while leading employee activism inside Google. And finally, can Substack stop the slop? We’ll talk about the platform’s new A.I. detector.
