Anthropic’s Claude Mythos Model Triggers National Security Alarm

(2 newsletters)

Fed Chair Jerome Powell and Treasury Secretary Scott Bessent convened an emergency meeting this week with the CEOs of Bank of America, Citigroup, Goldman Sachs, Morgan Stanley, and Wells Fargo. The reason: Anthropic’s new Claude Mythos model can find cybersecurity vulnerabilities in operating systems and browsers at a scale that dwarfs human capability, reportedly identifying “thousands” of critical flaws per year versus a human team’s roughly 100. Anthropic distributed the model to only about 40 organizations, citing it as too dangerous for broad public release. Officials believe it could debilitate Fortune 100 companies, infiltrate national defense systems, and take down large portions of the internet. Separately, Anthropic announced “Project Glasswing,” a defensive cybersecurity partnership with Amazon, Microsoft, Apple, Google, CrowdStrike, Palo Alto Networks, and Nvidia — making for an unusually dense week of Anthropic news across the AI and business press.

OpenAI Launches $100/Month Codex Plan

(2 newsletters)

OpenAI added a new $100/month tier to ChatGPT sitting between its existing $20 Plus and $200 Pro plans. It offers 5x more Codex capacity, full access to all Pro models, and a temporary 10x Codex boost for new subscribers through May 31. Sam Altman cited surging developer demand and users switching from competing tools as the driver. For context, Codex is OpenAI’s coding-focused model, and the new tier is positioned squarely at developers who keep hitting usage limits on the cheaper plan.

Shower Thoughts

No newsletter today included a dedicated “Shower Thoughts” section. But Morning Brew’s Investing Brew asked readers for their investing philosophy in one sentence. A few worth keeping: “Invest in something that’s so boring you don’t bother to check it.” — James from Illinois “You either know nothing and just invest regularly in an index fund, or you know everything and do this for a living; there is no in between.” — Perron from Austin, TX “Don’t.” — Dakotah from Maryland
