The API has introduced a “self-selected service provider” mode, with discounts as deep as 80% (down to 2 折), offering a compromise between stability and saving money.

The biggest difference in this update is that choice has been opened up:
For core business needs that require stability, use the official mode—directly connected to the original manufacturer and focused on handling high concurrency.
If you’re running your own tests or need to push costs as far as possible, switch to a self-selected service provider, where the price can be cut to 2 折 (80% off).
