All-day off-peak credit rates
Z.ai's GLM Coding Plan page now states that all-day usage is charged at the off-peak rate from September 25 to October 7, 2026. That means 50% credit consumption throughout the day during the promotion.
The plan supports coding tools including Claude Code, Cline and OpenCode. Each plan remains subject to both a five-hour usage limit and a weekly usage limit.
Overnight Flash usage campaign
The page also lists a September 3 to October 7 campaign running daily from 23:00 to 09:00 the following day. Paid plan users can use GLM-5.3-Flash without usage limits through ZCode and AutoClaw during that window, with doubled quota on other agents.
