This topic describes the billing rules and prices of AI models.
Billing overview
Most text and multimodal generation models are billed based on input and output tokens. Models such as embedding and reranking models are billed only on input tokens; output tokens are not charged.
Tiered billing
Some models use tiered billing. The unit price depends on the total number of input tokens in a single request. All tokens in the request are billed at the unit price for the applicable tier.
For example, assume that a model has two billing tiers: 0 < tokens ≤ 32K and 32K < tokens ≤ 128K. If a request contains 100K input tokens, it falls within the second tier (32K < 100K ≤ 128K), so all tokens in the request are billed at the second-tier unit price.
