Claude Sonnet 5 lands, and Fable 5 returns
The Claude 5 family fills out on Anuma this week: Claude Sonnet 5 replaces Sonnet 4.6 everywhere you pick a model, and Claude Fable 5 — Anthropic's frontier Mythos-class model — returns for Pro subscribers. Mobile gets a matching Council Mode redesign, independent per-chat streaming, and home suggestions personalized from your memories. And a new opt-in PII redaction setting strips emails, phone numbers, and card numbers from your messages before they ever reach a model provider.
