What DeepSeek does in mental health & psychology

Core tasks in mental health & psychology
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 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 deploying it in mental health & psychology.

Confidentiality and GDPR

GDPR: Caution

Mental health records contain special category personal data (health data, GDPR). Only use systems with 7510 certification, a data processing agreement and EU hosting; audio recordings of therapy sessions must not be sent unencrypted to external servers. AI-supported diagnostics and treatment decisions fall under the EU AI Act (high risk) and require human oversight and an audit trail. A BIG-registered professional remains ultimately responsible for the content of the record.

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.
