About Anthropic's pricing
Anthropic's four Claude models share prompt caching as a pricing mechanic, but at different discount depths — Claude Fable 5.1's cache-hit rate (0.025x base input) is the deepest discount Anthropic publishes. Claude Sonnet 5's pricing has also moved recently: a scheduled increase to $3/$15 was cancelled, leaving $2/$10 as the standing rate.
