What GLM (Z.ai) does in notaries

Core tasks for notaries
What GLM (Z.ai) is strong at
  • Top performance on coding and agent benchmarks at a fraction of the price
  • GLM-5.2 is fully open-weight under the MIT licence
  • 1 million tokens of context on the flagship
  • Affordable Coding Plan subscriptions for tools such as Claude Code

GLM (Z.ai) raises a concrete GDPR concern. Parent company Zhipu (Beijing) falls under 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 notarial work.

Confidentiality and GDPR

GDPR: Caution

Notaries are bound by strict confidentiality (art. 22 Wna) and liability for the content of deeds. Client data is personal data under the GDPR; audio recordings of signing meetings must not be sent unencrypted to external servers. Only use systems with EU hosting and a data processing agreement, where input is not used for model training. AI output for deeds and advice always requires verification by a qualified notary.

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.
