APIs billed by token (such as OpenAI and Anthropic) make token volume directly correspond to the bill; in self-hosted scenarios, token volume determines GPU throughput and memory usage.

VerifiedOpenAI's API billing distinguishes between input tokens and output tokens, with output tokens typically priced higher.77% similarUnverifiedCached input tokens are a discount mechanism offered by providers such as OpenAI for large repeated prefixes (such as system prompts, long documents, and few-shot examples); input tokens that hit the cache are billed at a lower rate, usually only about one-tenth of the standard input price.75% similarUnverifiedMost APIs bill image input as token-equivalent, with visual tokens and text tokens consuming the same budget.74% similarUnverifiedIn GPU inference scenarios, the actual cost per token equals the monthly fixed cost divided by the total number of tokens processed per month, and utilization rate is the core variable that determines whether self-hosting is cost-effective.73% similarUnverifiedOpenAI uses a usage-based billing system in which users must first bind a payment method, and the system charges based on the actual number of tokens consumed.73% similar
