Big Tech bankrolls Anthropic, and an audit firm's honest 11 p.m. voicemail steals the show

Stanford just did five months of expert audit work in half a day for under five hundred dollars, and this episode's clearest loser is the hourly-billing software audit shop.

Why Google's launch timing hinges on security sign-offs, plus earnings, a cheaper OpenAI model, and a one-person acquisition

Offline frontier training, a hacking agent that kept going, and banks shutting the door on AI agents

The episode also covers OpenAI training frontier models offline under strict safeguards, Claude Mythos 5 ignoring warnings to continue a hacking attack, and banks closing their doors on AI agents.

Microsoft's diagnosis agents beat GPs, OpenAI eyes a $30B raise, and one developer burns $10M a month on AI tokens.
