AI Weekly: 4/1–4/10 | Anthropic Triple Shock Sequel — Mythos Too Dangerous to Ship, Revenue Passes OpenAI, Software Stocks Crash

The Mythos model that leaked last week made its official debut this week — and Anthropic refused to release it publicly after it found thousands of zero-day vulnerabilities. Same week: Anthropic's revenue hits $30B and surpasses OpenAI, OpenAI closes the largest private funding round in history at $122B, Meta debuts its first closed-source model under Alexandr Wang, Google's Gemma 4 beats models 20x its size, and Musk teams up with Intel to build the Terafab chip megafactory.
