The 5.5 flagship, priced against a collapsing middle. Claude Opus 5.5 (September 22) is the long-running agentic-coding tier of the family: $10 per million input tokens and $50 output, five times Sonnet 5.5’s card, for work that runs for hours - multi-file changes, sustained tool loops, GDPval-AA’s 1846 top-score in the family (Sonnet 5.5 landed two points behind at a fifth of the price). Anthropic’s own pricing table now reads as a router: flagship for the deep end, the Sonnet for everything scoped.
Hosted only. No weights, no local run, no independent replication; scores above are Anthropic-reported and the comparability question from the Sonnet card applies identically.
