GLM (Z.ai) raises a specific GDPR concern. Parent company Zhipu (Beijing) is subject to Chinese data and security legislation, regardless of where the servers are located. For sensitive data, self-hosting the MIT-licensed weights is the recommended mitigation. Weigh this heavily before deploying it in radiology & medical imaging.

Confidentiality and GDPR

GDPR: Caution

Image analysis AI is a medical device: only use software with a CE marking under the MDR (class IIa or higher) for the exact purpose you deploy it for, and document how you validate and keep monitoring performance locally. You process special category personal data: ask where images are processed (on-premise, EU cloud or outside), whether they are pseudonymised and whether they are used for training, and sign a data processing agreement. Many vendors run on AWS or Azure or have been acquired by US groups, so check the current data location. The radiologist remains ultimately responsible for the report.

The international service Z.ai runs through JINGSHENG HENGXING TECHNOLOGY PTE. LTD. (Singapore); personal data is in principle processed in Singapore. According to the data processing agreement, API content is processed in real time and not stored. GLM-5.2 is open-weight under MIT and can therefore be fully self-hosted or hosted through an EU provider.

Rule of thumb Use the business variant with a data processing agreement, and keep a human in the loop for decisions that matter.
