E-MapReduce:Model calls (pay-as-you-go)

Last Updated:Mar 19, 2026

Pay-as-you-go is a billing method where you pay for services after you use them. Fees are calculated based on the token usage of built-in models in the AI Center of your workspace.

Note

The AI Center is currently in a free trial period. Commercial billing is scheduled to start on April 8, 2026. For more information, see EMR Serverless Spark AI Center Commercialization Announcement.

Billing rules

Billing is based on the token usage of built-in model services in a workspace within a one-hour billing cycle. The billing rules vary for different built-in models:

  • qwen-plus: Billed based on input tokens and output tokens.

  • text-embedding-v4: Billed based on input tokens. Output tokens are not billed.

The cost for model calls is calculated as follows: Input token usage × Unit price for input + Output token usage × Unit price for output

For example, if you call `ai_query()` 10,000 times in the China (Hangzhou) region, with each call having 260 input tokens and 50 output tokens, the cost is calculated as follows: 0.00096 × 260 × 10000 ÷ 1000 + 0.0024 × 50 × 10000 ÷ 1000 = 3.696 CNY.

Note

To estimate token usage, see the Model calls subsection in Billable items and billing methods.

Billing cycle

Fees are calculated on the hour, every hour (UTC+8). A new billing cycle begins after each calculation. At the end of each billing cycle, the system generates a bill and deducts the fees from your account. There may be a delay between the actual resource consumption and the data that appears on your bill. For more information, see Bill usage instructions.
