BlockBeats News, February 21 — Zhipu issued an apology letter regarding its AI programming subscription plan GLM Coding Plan and announced a handling and compensation plan. Zhipu stated that the main issues in this revision were threefold: insufficient transparency of rules, slow rollout of the GLM-5 grayscale phase, and rough design of the upgrade mechanism for existing users. After the release of GLM-5, traffic exceeded expectations, and the scaling pace could not keep up, leading to the phased rollout of GLM-5 according to Max, Pro, and Lite. Currently, Max users have full access, Pro users have been granted access but may experience rate limiting during peak times due to high cluster load, and Lite users will be gradually opened in grayscale after the holiday during non-peak hours. Zhipu supports affected Lite and Pro users in applying for refunds independently.
