Summary

During the GLM-5.3-Flash Global Build campaign (Sep 3–20, 23:00–09:00 SGT), ZCode is documented to provide zero-quota / unlimited usage for GLM-5.3-Flash.

However, if the regular Coding Plan Weekly/Monthly quota is already exhausted, ZCode appears to short-circuit with the normal quota gate before the Global Build entitlement is evaluated.

In my case, I also have the Weekend Build IV 300M-token Start Plan active. During the Global Build unlimited window, requests do not use the zero-consumption Global Build route; instead, the Weekend Build 300M balance is consumed.

Error

Weekly/Monthly Limit Exhausted. Your limit will reset at 2026-09-10 06:54:23

### 复现步骤 · Steps to reproduce

1. Have an active paid Z.AI Coding Plan.
2. Exhaust the normal Weekly/Monthly quota to 100%.
3. Enter the Global Build campaign window (23:00–09:00 SGT / 00:00–10:00 KST).
4. In ZCode, select and use GLM-5.3-Flash.
5. Observe that the Global Build zero-consumption entitlement does not engage.
6. If Weekend Build IV / Start Plan 300M tokens are available, requests consume that 300M balance instead.
7. Without another usable entitlement, the request is blocked with Weekly/Monthly Limit Exhausted.

### 期望表现 · Expected behavior

According to the official campaign documentation:

[https://docs.z.ai/devpack/notice/event-glm-5.3-flash](https://docs.z.ai/devpack/notice/event-glm-5.3-flash?utm_source=chatgpt.com)

GLM-5.3-Flash in ZCode should have zero quota consumption / unlimited usage during the campaign window.

Therefore:

- Global Build should work even if the normal Weekly/Monthly quota is already exhausted.
- The normal quota admission check should not block campaign-eligible GLM-5.3-Flash requests.
- Weekend Build IV 300M tokens should not be consumed while Global Build zero-consumption is active.

### 实际表现 · Actual behavior

Observed behavior appears to be:

baseline quota check
  -> Weekly/Monthly quota exhausted
  -> normal Coding Plan access rejected
  -> Global Build entitlement is not applied
  -> Weekend Build / Start Plan balance is used instead if available

As a result, the Global Build unlimited campaign becomes unusable for users who reached 100% quota before entering the campaign window.

_No response_

The issue names no source files or tests; start by reproducing the exhausted Weekly/Monthly quota case during the Global Build window with GLM-5.3-Flash, then trace the quota admission and entitlement evaluation described in the report. Done means eligible requests bypass the normal quota gate, use the zero-consumption Global Build entitlement, and do not consume Weekend Build balance.
