# The Open Weight Revolution with Simon Willison > Source: > Published: 2026-07-31 14:00:00+00:00 Simon Willison joined Bryan and Adam to discuss a wild couple of weeks in AI. First, we have a high-profile, AI-induced, AI-diagnosed security incident. Next we have the rise of frontier-class open-weights models. Who's for or against open weights? Do they make for a more or less secure future? Exciting times! In addition to [Bryan Cantrill](https://bsky.app/profile/bcantrill.bsky.social) and [Adam Leventhal](https://bsky.app/profile/ahl.bsky.social), our special guest was [Simon Willison](https://bsky.app/profile/simonwillison.net). Previously, on Oxide and Friends: Some of the topics we hit on, in the order that we hit them: If we got something wrong or missed something, please file a PR! Our next show will likely be on Monday at 5p Pacific Time on our Discord server; stay tuned to our Mastodon feeds for details, or [subscribe to this calendar](https://calendar.google.com/calendar/ical/c_318925f4185aa71c4524d0d6127f31058c9e21f29f017d48a0fca6f564969cd0%40group.calendar.google.com/public/basic.ics).
