Anthropic Intelligence Monitor

Anthropic launched Claude Fable 5 on June 9, 2026 — the first Mythos-class model made safe for general public use. Priced at $10/$50 per million tokens, it outperforms Opus 4.8 by 10%+ on benchmarks, features a 1M-token context window, and comes with safety classifiers that fall back to Opus 4.8 for high-risk queries. A restricted sibling, Claude Mythos 5, goes to US government cyberdefenders only via Project Glasswing.

Anthropic confidentially submitted an S-1 to the SEC on June 2, 2026, days after closing a $65B Series H at a $965B post-money valuation. Run-rate revenue has crossed $47B annually.
