In our system, "groups" carry special meaning, reflected mainly in three areas: channels, pricing, and freedom of choice.

1. Channel Source Differences

• The same model (such as GPT or Claude) may map to different channel sources in different groups
• Different channel sources directly produce cost differences between groups, which leads to different pricing

2. Price Diversity

• API prices on the market are inconsistent, and one root cause is the difference in channels and cost structures
• We follow a transparent pricing policy: prices and rules are clearly displayed and fully verifiable

3. User Choice

• Users can choose the group that suits them best based on performance, stability, price, and other factors
• This provides more flexible, personalized configuration options for different budgets and scenarios

Official Rate Explained

To help users intuitively understand how each group's price relates to the official list price, we introduce the concept of the "official rate":

• Billing on this site is in CNY (RMB)
• Prices shown on the model page are the official list prices (converted to RMB)
• Each group's final billed price = official list price × group rate

Rate Examples

1. Group rate = 1

   • Billed at the official list price (identical to the official price)

2. Group rate = 0.4

   • Billed at 0.4× the official list price (i.e. 60% off)

Through the "official rate", users can compare price differences between groups more clearly and make the choice that best fits their needs and budget.
