Is Sonnet 5 Even Worth It? Plus: Fable's Back, and War on Tokenmaxxing | This Week In AI

July 9, 2026

Anthropic lived rent-free in everyone's feed this week. Claude Sonnet 5 launched as "the most agentic Sonnet yet" — and within 24 hours, the government lifted the export controls on Fable 5 and Mythos 5. Shane and Abhi unpack both, plus the catch: Fable came back wrapped in new classifiers that quietly fall it back to Opus for coding, and it's coming off subscription plans on July 7.
