Prompt caching is the cheapest Claude optimization. Nobody measures it.
Developers using Anthropic's Claude API are likely overspending due to a lack of awareness about prompt caching. The API provides data on cache hits and misses, which can significantly reduce costs if utilized effectively. By monitoring cache performance, developers can identify and fix issues that lead to unnecessary expenses, such as personalized prompts or subtly changing query parameters. AI
IMPACT Developers can significantly reduce Claude API costs by implementing prompt caching observability.
