Assessment
Reasoning: Zhipu's GLM models, offered internationally as Z.ai from Singapore and domestically through bigmodel.cn. The chat product's data feeds model improvement and is kept for the life of the account; the API terms state inputs are not stored. Zhipu is a Beijing company and the group may transfer data between affiliates.
Flags: Chat data used to improve models · Chinese vendor, Singapore processing · API inputs not stored · Assessed 2026-09-16. The assessment is Unseen's; the terms above are the vendor's.
