VerifiedThe Claude API supports a Prompt Caching mechanism, where content is billed at full price on the first request, and subsequent tokens that hit the cache cost approximately 10% of the original price77% similarUnverifiedBoth Anthropic's Claude API and OpenAI's API natively support prompt caching, with input token prices on cache hits typically only 10%–25% of the normal price.77% similarUnverifiedIn the caching mechanism, output tokens do not benefit from the input cache discount, causing Claude samples to gain less from caching because more of the API value is spent on output tokens.74% similarUnverifiedClaude's input tokens are typically approximately 3–5 times cheaper than output tokens, because the generation process requires autoregressive token-by-token inference.70% similar
