What moved
Claude Pro listed Fable 5.1, Fable 5 and Sonnet 5; Max 5x and Max 20x listed Fable 5.1, Fable 5 and Opus 4.8 → Claude Opus 5.5 added to Claude Pro, Max 5x and Max 20x at the Anthropic API list rate $4 input / $20 output / $0.20 cached read per 1M
Anthropic own subscription tiers now carry Claude Opus 5.5: the claude.com/pricing Models grid marks Opus as included on Pro, Max 5x and Max 20x, and the same page API tab publishes the model at $4 input / $20 output per 1M with $0.20 cached read and a $5 cache write. The tracked plan records had not yet been re-checked against the model, so this entry adds it to all three, priced with the Anthropic list rates the calculator already uses as the comparability proxy for these consumer plans.
