Note

This topic describes only the billing items and billing methods. For more information about the pricing of billing items, see OSS Pricing.

Billing details

Billable item	Billing rule	Billing cycle	Billing method
OSS accelerator (AcceleratorCacheSize)	You are charged based on the provisioned capacity of the OSS accelerator and the duration of usage. Important When using this feature, you are charged based on the capacity of the accelerator that you request, regardless of the actual volume of data stored. For example, if you provision 100 GB of accelerator capacity and prefetch 50 GB of data, you are still charged for the full 100 GB provisioned capacity.	Bills are generated on an hourly basis (generally after a billing cycle ends). The time when bills are generated is determined by the system.	Pay-as-you-go: Accelerator charges = Provisioned capacity × Duration of usage × Unit price per GB Resource plans are not available.

Billing examples

Example 1: Use an OSS accelerator to accelerate development work

Mr. Li plans to activate a 50 GB OSS accelerator in the China (Beijing) region at 8:00 on July 1, 2025, to accelerate reasoning model files and improve the loading speed of text-to-image models during daytime creative work. He plans to delete the accelerator at 18:00 after work on the same day.

Operation	Billing item	Billing item code	Unit price	Billing volume	Daily fee
Create a 50 GB accelerator instance at 8:01 on July 1, 2025. Delete the accelerator at 17:30 on July 1, 2025.	OSS accelerator cache capacity	AcceleratorCacheSize	CNY 0.7/GB/month (CNY 0.000972/GB/hour)	50 GB × 9.5 hours	50 × 9.5 × 0.000972 = CNY 0.462

Example 2: Temporarily scale out an OSS accelerator to handle daily business peaks

Mr. Zhang regularly uses a 1,024 GB accelerator for acceleration and plans to temporarily increase the accelerator capacity to 2,048 GB in the China (Beijing) region during peak business hours (17:30 on July 1, 2025). After the peak period ends, he plans to restore the capacity to 1,024 GB at 22:00 on the same day.
