    E-MapReduce:AI Function

    Last Updated:Apr 15, 2026

    AI Function uses a pay-as-you-go model, billing you for the exact number of tokens the built-in model consumes in your StarRocks instance. In each billing cycle, the system automatically generates a detailed bill and deducts the corresponding fees, ensuring transparent, pay-for-what-you-use pricing.

    Billing

    Note

    Each user receives a free quota of 1 million tokens for the first month. Usage exceeding this quota is billed at the standard rate.

    Feature

    Description

    Billing rules

    Fees are based on the token usage of the built-in model in your StarRocks instance. Billing rules vary by built-in model.

    Model invocation fee: token usage within one hour × unit price for the region, model, and token type (input/output)

    Billing cycle

    Fees are calculated hourly on the hour (UTC+8). A new billing cycle begins after the settlement. At the end of each billing cycle, the system generates a bill and deducts the corresponding fees from your account. Billing data may be delayed. For details, see Understand Alibaba Cloud Bills.

    Pricing

    Important

    Prices are subject to change. For the latest pricing, please refer to the product purchase page.

    AI Function currently uses the qwen-plus model for inference. Input and output tokens are billed separately.

    The following examples show how AI Function fees are calculated.

    Billing conditions

    Cost (USD)

    • Region: US (Virginia)

    • Function call: ai_query()

    • Input tokens: 750

    • Output tokens: 20

    Cost = Input Cost + Output Cost

    = 0.000480 × 750/1000 + 0.001440 × 20/1000

    = 0.000360 + 0.000029

    = USD 0.000389
