Some API providers cache repeated context to reduce costs, but the caching strategy is opaque; the meter may still display usage by the full token count, or billing rules may differ depending on whether the cache hits.

UnverifiedDifferent AI providers differ in cache granularity, hit conditions and billing methods; for example, some price cache-write tokens and cache-read tokens separately, and some set a minimum cacheable token length.79% similarUnverifiedCost data is not affected by sampling fluctuations because token counts and API billing are deterministic values and the payload size returned by the same API for the same query is essentially constant.75% similarUnverifiedCached input refers to pre-storing the same context on the server side so that subsequent requests can reuse the cache without repeated computation, and is billed at a lower price.74% similarUnverifiedSome image API vendors bill per "successful generation" (failed requests are not billed), while others bill per "API call" (regardless of whether the output is usable); in scenarios requiring multiple retries, the actual cost of the latter may be far higher than the listed price.73% similarUnverifiedWhen migrating to this API, you need to check whether the old and new definitions match, especially the boundaries of token counting (for example, whether cache hits are included and whether input and output tokens are distinguished), and whether cost calculation uses the same unit prices as billing.72% similar
