Zhipu AI's Coding Plan rolls out promotions during the Double Festival: Flash Night is free, FlashX is open for trial.

Beating AI Express News: Zhipu AI launches Double Festival promotions for its GLM Coding Plan. The overnight free access for GLM-5.3-Flash, originally scheduled to end on September 20, has been extended to October 7. From 23:00 to 09:00 daily, using Flash in ZCode will not deduct credits; other supported Agents will receive double the Flash quota. From September 25 to October 7, peak hours will be eliminated, with all-day credit deductions calculated at off-peak rates. Under the new Coding Plan, peak hours are normally only 14:00 to 18:00 on weekdays, with 50% credits consumed at all other times. During the Double Festival period, the full day will be charged at this off-peak rate. Meanwhile, the newly launched GLM-5.3-FlashX is now rolling out trials for Coding Plan users. After submitting and passing an application, users can experience it for two weeks. FlashX has a maximum output speed of 200 tokens per second, but consumes 2.5 times the quota of regular Flash.
