How much can I save with Claude prompt caching?

Users can typically see a reduction in latency of up to 85% and a reduction in costs by up to 90% for content that is repeatedly read from the cache.

Which Claude models support this skill?

Prompt caching is supported on the latest generation of models, including Claude 3.5 Sonnet, Claude 3.5 Haiku, and Claude 3 Opus.

What is a cache breakpoint?

A cache breakpoint is a flag added to your API request that tells Claude exactly which part of the prompt (like a large document or a list of tools) should be stored in memory for future use.

Is there a minimum token limit for caching?

Yes, caching generally requires a minimum of 1024 to 4096 tokens depending on the model, making it ideal for large system prompts and long documents.

How long does a cached prompt last?

The default TTL (Time-To-Live) is 5 minutes, which is perfect for interactive chat. For batch processing, you can extend the TTL to 1 hour.

Optimizes API performance and reduces operational costs by caching static prompt segments and conversation history.

概要

The Prompt Caching skill enables developers to leverage Anthropic's sophisticated caching mechanisms to achieve up to an 85% reduction in latency and a 90% reduction in API costs. By strategically implementing cache breakpoints within tool definitions, system prompts, and message histories, this skill allows for the persistence of large contexts like RAG documents, complex codebases, and long-running interactive sessions. It provides standardized implementation patterns and monitoring utilities to ensure your Claude integrations are both lightning-fast and highly cost-efficient.
