Anthropic cuts claude-sonnet-5-5 cached input from 0.2 to 0.1 USD per MTok
Anthropic's price list now shows claude-sonnet-5-5 cached input at 0.1 USD per MTok, down from 0.2, while input holds at 2 and output at 10. The move is asymmetric: only the cached-input rate changes, which lowers the cost of repeated-context workloads (agents, long system prompts) on Anthropic's mid-tier model without touching list input or output pricing.
