September 4 News.Zhipu Yesterday, AI announced the official launch of the “Flash x ZCode” night campaign under the flag of the GLM Coding Plan。

From 23:00 p.m. to 09:00 p.m., from September 20th, all pay-for-meat users will not be required to open manually, and the system will automatically become effective. During the event, the GLM-5.3-Flash model consumption rules for the GLM Coding Plan package were as follows:
- ZCode, when used, consumes 0 to completefreeClear。
- The amount available for other Agents supported by the package doubled (x2)。
1AI Reminder: This event is only for the GLM-5.3-Flash model, and if GLM-5.3 is selected during the wrong period of time, it will continue to be consumed in accordance with the standard set. The duration of the event is based on Beijing time (UTC+8), including weekends and public holidays。
GLM-5.3-Flash is the first primary multimodular model of the GLM-5 series, supporting 1 million token context windows and multimodular input of text, images and videos。
The model once appeared on the OpenRouter platform as an anonymous "Ox Alpha" and, after its discovery, was ranked first on the OpenRouter list, using more than twice as much as DeepSeek。
Accomplish 57 points in Artificial Analysis Inteligence Index (AA Comprehensive Smart Index) to enter the global frontier model capability range, suitable for code generation, code understanding, problem repair, etc., while there is a significant increase in Office and document type assignments, financial, legal, etc。
