Dynamic rate limiting
Bailian applies dynamic rate limiting to some models. The TPM rate limit value is adjusted monthly based on your Bailian monthly consumption tier, and the actual available TPM is no lower than the rate limit value.
Dynamic rate limiting mechanism
Bailian applies a dynamic rate limiting mechanism to some models. The key points are as follows:
- Rate limit value: Determined by tier based on your monthly consumption amount on Bailian. It serves as the guaranteed baseline for throughput and is adjusted every month.
- Soft rate limiting: When the call volume reaches the rate limit value, if the platform still has spare resources, rate limiting is not triggered. Therefore, the actual available TPM is no lower than the rate limit value. The actual rate limit value observed during calls may be higher than this rate limit value, which is expected behavior.
- Rate limit granularity: By account + model. The call volumes of all workspaces and API Keys under a primary account are aggregated and counted toward the TPM quota for that account for that model, sharing the same limit.
- Workspace: You can set a separate rate limit value for a model in a workspace. Workspaces without a separate setting share the account-level quota.
- RPM: Under the dynamic rate limiting mechanism, a model has a relatively large RPM limit. You do not need to set it separately, and RPM rate limiting is not triggered during normal use.
- More information: For the basic concepts of RPM/TPM and details by dimension, see Rate limiting. For workspace rate limit settings, see Permission management.
Models and rate limit tiers
The TPM rate limit value is tiered based on the monthly consumption amount on the Bailian platform. The tiers for supported models in different regions are as follows (values are subject to the actual display in the console):
China (Beijing)
Bailian platform monthly consumption: | Tier 1 (current) ≤¥100,000 | Tier 2 ¥100,000~¥1,000,000 | Tier 3 >¥1,000,000 |

Take China (Beijing) as an example: if the Bailian consumption amount of an account in the previous calendar month was 500,000, it falls into the Tier 2 (¥100,000~¥1,000,000) tier, corresponding to a TPM rate limit value of 10,000,000 for qwen3.8-max.
Quota display
Log in to the Bailian console. In the left-side navigation pane, choose Model rate limits to go to the model rate limits page.
The model rate limits page is a read-only page that displays the models that support dynamic rate limiting, the current TPM rate limit value, and the Bailian consumption tier. The top of the page shows the current effective period (such as 2026-08-15 to 2026-09-15), last month's consumption (calculated by the previous calendar month, such as August 1 to August 31), and this month's consumption amount. You can click View consumption details to view consumption details, and click View rules to view the rate limit tier rules. The table below lists the TPM rate limit tiers for each model.
NoteIf the TPM rate limit value cannot meet your business needs, contact your account manager to apply for a quota increase.
Dynamic rate limit adjustment strategy
Rate limit tiers are dynamically adjusted according to the following rules:
- Tiering basis: Bailian platform consumption amount.
- Calculation cycle: Calculated by calendar-month billing cycle.
- Notification: A notification is sent to the affected users on the 10th of each month.
- Effective time: The new tier takes effect on the 15th of each month and is valid until the 15th of the following month.
- Adjustment direction: Lower tier → higher tier (upgrade) or remain unchanged.
