This week, OpenAI released its much-anticipated flagship model, GPT-5. We break down what we know about the upgrade, drawing from our initial testing and a special news briefing with Sam Altman. Then, we explain why we were underwhelmed by Amazon’s new Alexa+, which is powered by generative A.I., and take our feedback to Daniel Rausch, vice president of Alexa and Echo, who helps us understand why powering Alexa with L.L.M. capabilities is a major computer science challenge.

Guests:

• Daniel Rausch, Amazon vice president of Echo and Alexa
