Anthropic has introduced the Prompt Caching Dashboard within the Claude Developer Console, offering users detailed insights into caching performance. The dashboard, accessible at platform.claude.com/usage/cache, features metrics such as cache read ratio, cache usage composition, and write amortization. These metrics help users understand the efficiency of cache usage, with data presented in visual formats like stacked bar charts and time-series graphs. The dashboard allows filtering by workspace, model, and time period, providing a comprehensive view of caching activities. In a recent example, Claude Opus processed 27.4 billion input tokens over a week, achieving an 85.4% read ratio and a write amortization of 8.65x. This tool enhances the ability of API users to manage cacheable content, offering cost savings on subsequent cache hits compared to initial writes. Previously, users lacked visualization tools to assess caching effectiveness, relying solely on token count fields in API responses.
