Podcast examines the emergence of open weight models and recent AI industry challenges

In an Oxide and Friends episode, Bryan Cantrill and Adam Leventhal hosted Simon Willison to examine recent developments reshaping the AI landscape. The discussion centered on open weight models such as Kimi K3, which have demonstrated competitive performance against proprietary frontier systems. The episode also addressed cybersecurity concerns and covered an open letter backed by influential industry leaders regarding American leadership in open AI development. The hosts revisited earlier predictions while exploring tangential topics that emerged during their conversation. Willison noted that subsequent industry events — including DeepSeek V4 Flash and a cybersecurity incident at Anthropic — would have significantly enriched the discussion had they occurred prior to recording. The conversation encompassed industry trends and relevant data analysis. The participants concluded by adding a new year-end prediction: the possibility that the Pope might publicly comment on open AI models.
