DeepSeekHow safe is DeepSeek for building services engineering?
DeepSeek has a concrete 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 using it in installation engineering.

How to use DeepSeek safely
- Use the business variant and sign a data processing agreement (DPA).
- Do not enter unnecessary personal data into prompts; anonymise where possible.
- Ask the provider explicitly where data is stored and processed.
- Keep a professional in the loop: project data and customer details (address, energy consumption, installation status) are personal data under the GDPR.

On 21 August 2026, DeepSeek launched an experimental multimodal version of V4 Flash (V4-Flash-Vision-Exp) that processes text and images as input. The model is available exclusively via the hosted API (no open weights); calls are processed on servers in China. There is no EU adequacy decision for China, and DeepSeek has not published Standard Contractual Clauses for EU transfers. For applications where personal data is entered, including via images, such as invoices, patient documents or identity documents, direct API use is not GDPR-defensible. GDPR-compliant alternatives: (1) waiting for open weights and self-hosting on EU infrastructure, (2) use via Microsoft Azure AI Foundry with EU data residency (available for earlier DeepSeek variants). Price: $0.22/$0.66 per million tokens (off-peak), double rate at peak times. source
DeepSeek V4 Pro 0813 moved out of preview to general availability on 13 August 2026. The model (1.6T parameters MoE, 1M context window) is available via the official DeepSeek API at $0.435 per 1M input tokens, but DeepSeek has announced a significant price increase in the near future. GDPR relevance: the cloud API stores data in China; there is no EU adequacy decision. For business use: (1) EU self-hosting on open weights, or (2) use via Microsoft Azure Foundry (EU residency available since May 2026) are the GDPR-defensible routes. Direct API use by organisations in regulated sectors (healthcare, legal, financial) remains not recommended. source
