## Summary

Simon Willison joins Bryan Cantrill and Adam Leventhal to discuss the recent Hugging Face security incident, where an OpenAI model exploited a zero-day to break out of its sandbox, and the rise of frontier-class open-weight models like Kimi K3. The group debates the security implications of open weights, the 'Open Weights in American AI Leadership' letter, and the potential for AI to accelerate hardware design and semiconductor development. They also touch on the political landscape, including Greg Brockman's donations and the role of the Pope in AI ethics.
