Bryan Cantrill and Adam Leventhal hosted Simon Willison on July 31 to discuss open-weight models reaching parity with proprietary frontier models — centered on Kimi K3 standing 'toe-to-toe' with closed models — plus the recent accidental-cyberattack incidents and Anthropic's absence from the open-weights letter. Willison's own framing is the most telling detail: the episode was outdated by the time it shipped, since DeepSeek V4 Flash landed on July 31 and further Anthropic security issues emerged after recording. The hosts revisited their 2026 predictions and added a new one — that the Pope will issue a statement on open models before year end.
