What DeepSeek does in construction & installation

Core tasks in construction & installation
Where DeepSeek is strong
  • Very low API costs
  • Open weights (MIT), self-hostable
  • Strong at reasoning, maths and code
  • Large context window (1M tokens)

DeepSeek raises a specific GDPR concern. The DeepSeek service stores personal data in China and was blocked by the Italian regulator in January 2025. Not advisable for regulated sectors unless you host the model yourself within the EU. Weigh this heavily before deploying it in construction & installation.

Confidentiality and GDPR

GDPR: Caution

Construction drawings and tender documents are often confidential or commercially sensitive. Check where documents are processed and whether they are used for model training.

The DeepSeek service stores data in China and uses it for training by default (with an opt-out). Only an EU self-hosted variant of the open weights is defensible for sensitive data.

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