What GLM (Z.ai) does in installation engineering

Core tasks in installation technology
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) has a specific 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 using it in installation engineering.

Confidentiality and GDPR

GDPR: Caution

Project data and customer details (address, energy consumption, installation status) are personal data under the GDPR. Only use systems with a data processing agreement and EU hosting. Technical documentation from manufacturers may be protected by copyright; check the usage licence before loading it into an AI system. AI estimates are always a starting point, expert verification remains essential.

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.
