On February 21, Knowledge Atlas issued an apology letter regarding its GLM Coding Plan and announced handling and compensation measures. The company stated that the revision mainly involved three errors: insufficient rule transparency, an overly slow rollout schedule for its latest large model GLM-5, and a poorly designed upgrade mechanism for existing users.

According to the announcement, after the release of GLM-5, traffic exceeded expectations, and the company's capacity expansion did not keep pace. This necessitated a phased opening of GLM-5 in the order of Max, Pro, and Lite tiers. Max users now have full access, while Pro users have access but may experience throttling during peak hours due to high cluster loads. Lite users will be gradually granted access during off-peak periods after the holiday. The company is offering refunds to affected Lite and Pro users upon request.
