Consent for EU-Hosted LLMs (Mistral, Aleph Alpha)
It depends on the lawful basis. Sending personal data to any LLM — including EU-hosted models like Mistral or Aleph Alpha — is a processing operation under GDPR Article 4(2). Consent is one lawful basis (Article 6(1)(a)); legitimate interest (6(1)(f)) or contract performance (6(1)(b)) may also apply. EU hosting reduces transfer risk but does not eliminate the lawful-basis requirement.

- EU hosting (Mistral in Paris; Aleph Alpha in Heidelberg) removes Chapter V third-country-transfer risk but does not change the need for an Article 6 lawful basis
- If using consent: capture it freely-given, specific, informed, and unambiguous — and allow withdrawal as easily as it was given (Article 7)
- If using legitimate interest: complete the three-step LIA (purpose, necessity, balancing) and document it before processing begins
- AI Act Article 50 transparency: deployers of generative AI must inform users when they interact with AI-generated content — separate from GDPR consent
