The Challenge

Even with an efficient model like GPT-4.1 Mini, using the OpenAI API directly means data processing in the US. Especially for high-volume applications — customer service, content processing — potentially large amounts of personal data are transferred. The GDPR compliance of such third-country transfers remains legally uncertain.
