I. Top_up Pack Credit Configuration Adjustment

Effective time: 12:00:00, September 22, 2026 (Beijing time, already in effect).

Change content: During the AI DeepSign new product launch period, a limited-time bonus campaign was offered for the Top_up Pack (¥6,888 tier), granting an extra 100,000 Credits on top of the standard credit configuration. As this campaign has ended, Alibaba Cloud adjusted the Top_up Pack credit configuration at 12:00:00 on September 22, 2026 (Beijing time). Before the change: the Top_up Pack (¥6,888) included 800,000 Credits (including the campaign bonus). After the change: the Top_up Pack (¥6,888) includes 700,000 Credits (standard configuration), with the sale price unchanged.

Change content and impact: Newly purchased Top_up Packs follow the standard credit configuration, with the sale price unchanged. Credits in already-purchased Top_up Packs are not affected and can be used normally within their validity period. The Top_up Pack supports auto-repurchase; because auto-repurchase executes according to the product specification of your previous purchase order (800,000 Credits) and that legacy specification has been offline since this adjustment, auto-repurchase orders of some users may fail validation and fail to execute. Solution: manually purchase the new-version Top_up Pack (700,000 Credits) once, then reconfigure auto-repurchase; subsequent auto-repurchases will execute normally under the new specification.

II. deepseek-v4-flash Model Deprecation

Effective time: October 9, 2026 (subject to the actual change time).

Change content and impact: To continuously improve model performance and service experience, and to stay aligned with the iteration pace of upstream model platforms, AI DeepSign will deprecate the deepseek-v4-flash model on October 9, 2026. After deprecation, this model will no longer appear in the selectable model list and related calls will no longer be supported; tasks still selecting this model will not return results. Recommended replacement model: deepseek-v4-pro. Your purchased plans and Credits balance are not affected by this deprecation; Credits can continue to be used on other models supported by AI DeepSign.

1. If you have configured auto-repurchase for the Top_up Pack, please check the recent execution status of your repurchases; if a repurchase failure is found, manually purchase the new-version Top_up Pack once and reconfigure auto-repurchase.
2. If you are using the deepseek-v4-flash model, please complete model switching and business validation before October 9, 2026 to avoid impacting the stability of your online services.
