Anthropic has introduced a prompt caching feature for its Claude Opus 5 model, designed to significantly reduce costs and improve response times for repeated conversational inputs. By adding a simple `cache_control` parameter to API requests, developers can enable the model to store and reuse previous prompt segments. This feature can lead to substantial savings, with costs dropping by approximately 90% for cached tokens after an initial one-time creation fee, making it particularly beneficial for applications involving long or repetitive conversational histories.
