New tool cachebench monitors LLM prompt cache hit ratios

A new tool called cachebench has been developed to help developers monitor and manage prompt caching for LLM APIs, specifically targeting Anthropic and OpenAI. Prompt caching significantly reduces token usage and costs, but regressions can go unnoticed until monthly billing. Cachebench addresses this by wrapping client calls to track hit ratios, costs saved, and identify specific prefixes that cause cache misses, alerting developers to potential issues before they impact their budget. AI

IMPACT Enables developers to optimize LLM API costs by providing visibility into prompt cache performance.

    cachebench: stop finding out about prompt-cache regressions from the invoice

    <p>Prompt caching is the single highest-ROI feature shipping in LLM APIs right now. On Anthropic and OpenAI, a healthy cache hit ratio saves 50 to 90 percent of input tokens. On a long system prompt with a large RAG context, that is the difference between a sustainable agent and …
