Grok 4 and Perplexity's Comet Browser

In this episode, we discuss the launch of Grok 4 from xAI, Perplexity’s new Comet browser and the Rubio voicemail deepfake. We break down Grok 4’s benchmark scores on Humanity’s Last Exam, the SuperGrok Heavy tier with video generation APIs and xAI’s swift response to antisemitic content. We explore Comet’s AI sidebar assistant, privacy-first design and Perplexity’s plan to compensate publishers for using their content. Finally, we examine the security risks highlighted by the Marco Rubio deepfake voicemail and the urgent need for watermarking and detection tools.
