UnverifiedA Prompt Caching cache hit read costs only 0.1 times the base input price, while the initial write cost is 2 times the regular input price.65% similarUnverifiedToken caching (Prompt Caching) is a cost-optimization mechanism in large model APIs; when the same prefix appears repeatedly across multiple requests, the computation result can be cached and charged at a lower rate.65% similarUnverifiedIn mainstream API pricing structures such as Anthropic's, the unit price of cache-read tokens is only 1/10 to 1/30 of standard input tokens.65% similarUnverifiedOpenAI typically charges 4–6 times more for output tokens than input tokens, because the computation involved in generation far exceeds that of comprehension.64% similarVerifiedThe 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 price64% similar
