Billing
Flux uses Chinese Yuan (CNY / ￥) as the billing unit. Prices displayed in the model marketplace are the final billing prices (unit: CNY / 1M tokens or per request).
How Prices Are Calculated
Token-billed models charge for input, output, and cache usage. Check both the unit and the applicable context-length tier; 1M Token in the marketplace means 1,000,000 tokens. Other billing methods, such as image generation, follow the individual model's price description.
Group Multiplier
Different API key groups may have different multipliers. The multiplier is applied to the model's base price, and the marketplace already shows the adjusted price, which is the final unit price deducted from your balance.
Multipliers and client restrictions differ from group to group. Check Core Concepts and the group description in the model marketplace before choosing.
A group is a property of an API key and is unrelated to subscription plans.
Calculation Example
These hypothetical prices are not a current quote for any model. All prices are in CNY (￥) per 1M tokens:
| Item | Base price (￥/1M) | Group multiplier | Final unit price (￥/1M) |
|---|---|---|---|
| Input | 2.50 | 0.3 | 0.75 |
| Output | 15.00 | 0.3 | 4.50 |
Suppose a request generates 10,000 input tokens and 2,000 output tokens, with no cache usage or Fast Mode, and all tokens fall within the price tier above:
Input cost = 10,000 / 1,000,000 × 0.75 = 0.0075 CNY (￥0.0075)
Output cost = 2,000 / 1,000,000 × 4.50 = 0.0090 CNY (￥0.0090)
Total cost = 0.0165 CNY (￥0.0165)For actual calculations, use the final prices in the model marketplace, which already include the multiplier. For cached requests, check whether the protocol's input count includes cached tokens and which cache read/write prices apply. Refer to the usage logs for actual charges.
