Frequently Asked Questions

How does Anthropic prompt caching work?
Anthropic caches portions of your prompt (system, examples, long context) with an ephemeral breakpoint. Cache writes cost 1.25× input price (25% premium). Cache reads cost 0.1× input price (90% discount). Default TTL is 5 minutes, extended 1h TTL costs 2× write (2.5× base).
When does caching save money?
Break-even: ~2 reads for 5-min cache (1.25 write + 0.1×N ≤ 1.0×(N+1) → N ≥ 2). Real savings start at 10+ reads per write. At 100 reads/write, you pay 1.25 + 10 = 11.25 units vs 100 without cache = ~89% savings.
What should I cache?
Large static content: system prompts, instruction templates, few-shot examples, long documents, tool definitions. Don't cache: short prompts (<1024 tokens on Sonnet/Opus, <2048 on Haiku), rapidly changing content, PII that varies per user.
Minimum cacheable tokens?
Claude Sonnet 4 / Opus: 1024 tokens minimum. Claude Haiku: 2048 tokens minimum. Below this, caching is not applied.
