Anthropic Prompt Caching
A framework for building agents with Claude that supports prompt caching for efficient multi-turn conversations and agent memory.
Solid choice for most workflows
You need to build cost-effective conversational agents or multi-turn tools that reuse large contexts like documents, instructions, or tool definitions without exploding token costs.
Cache hits after first call on matching prefixes; 5-min TTL refreshes on use; up to 4 breakpoints; works best for 1k+ token prompts; monitor via response token fields.
Your agents process large documents or knowledge bases repeatedly, making every query slow and expensive due to full re-sending.
Dramatic speedups for doc Q&A, coding assistants, or shared examples; ephemeral-only cache type limits to short sessions; ideal for batch or iterative tool calls.
5-Minute Cache TTL
Caches expire after 5 minutes of inactivity (refreshes on hits), forcing recaching for long idle sessions or infrequent queries.
Exact Prefix Match Required
No cache hit if prompt prefix changes even slightly—order static content first and keep it identical; monitor `cache_read_input_tokens` to confirm hits.
Anthropic offers manual control and breakpoints vs OpenAI's auto 1k+ token caching.
Pick Anthropic for precise caching of tools/system/docs in agent loops or when using Claude models.
Pick OpenAI for hands-off caching on long GPT prompts without config tweaks.

What It Actually Does
Anthropic Prompt Caching lets you mark static parts of prompts—like system instructions or long documents—for reuse in follow-up requests with Claude AI, cutting costs and speed by skipping reprocessing of unchanged text.[1][4]
