+    In Teable Cloud, Teable sends automation run usage notifications to Space Owners when a space is close to or over its run quota, or when runs increase sharply in a short time.
+
+    For quota reminders, Teable sends a notification when the current billing period reaches 80% or 90% of the available run quota.
+
+    Pro and above plans may receive alerts after automation runs go over the quota. Teable may remind you about every 6 hours.
+
+    Teable Cloud may also send critical notifications for unusual usage, such as a large daily increase or a sudden burst in a short time. The system uses recent daily and hourly run patterns, and the exact thresholds may change.
+
+    The notification opens **Space Settings** → **Billing**. When available, it shows which workflow and Base contributed the most runs. Quota reminders are based on runs counted toward your plan limit; unusual usage checks may also consider recent runs with **success**, **failed**, or **pending** status.
+
+    If the usage is expected, consider buying extra automation quota or changing your plan. If it is unexpected, review the top workflow and adjust or pause the related automation.

     One AI Chat or App Builder run can include multiple processing steps. The conversation and billing page both show the total credits for that run. Work that Cuppy already completed and saved can still be used. If the final step is interrupted by an unexpected error, credits for that interrupted step are refunded automatically. You can continue working in the same conversation.

   <Accordion title="Why didn't my credits increase after adding a new collaborator?">
     Credits are allocated based on your billed seat count. When you add new billable collaborators, the seat count is updated at the start of the next billing cycle. Credits for new seats are allocated at that point on a prorated basis. If credits are needed before then, add-on credits can be purchased for instant use.

+  <Accordion title="为什么会收到自动化运行次数提醒？">
+    在 Teable Cloud 中，当空间的自动化运行次数接近或超出额度，或短时间内运行次数明显增加时，Teable 会向空间所有者发送用量通知。
+
+    对于配额提醒，Teable 会在当前计费周期的自动化运行次数达到额度的 80% 或 90% 时发送通知。
+
+    专业版或以上计划在自动化运行次数超出额度后，可能会收到提醒。之后可能约每 6 小时提醒一次。
+
+    Teable Cloud 也可能因为异常用量发送关键通知，比如单日运行次数明显增加，或短时间内突然运行很多次。系统会参考近期的日级和小时级运行模式，具体触发阈值可能调整。
+
+    通知会打开**空间设置** → **计费**。如果能识别主要来源，通知会显示哪个工作流和 Base 贡献了最多运行次数。配额提醒基于计入套餐额度的运行次数；异常用量检测也可能参考近期状态为**成功**、**失败**或**等待中**的运行。
+
+    如果这些用量符合预期，可以考虑购买额外自动化额度或调整订阅计划。如果用量不符合预期，请查看主要工作流，并调整或暂停相关自动化。
