AI Model Providers

In BYOK mode, your verification request is processed by AI providers you select using your own API keys. In Hosted mode (currently restricted to selected beta administrators), the Service uses our credentials. In both modes, task text passes through our server for verification orchestration.

Note on PRC-origin models: Some models (e.g., DeepSeek R1) were developed by companies headquartered in the People's Republic of China. When accessed through Microsoft Azure or Amazon Web Services, data is processed by Microsoft / Amazon, not by the original developer. Data remains in EU/US jurisdiction and is covered by the hosting provider's DPA.

Prohibited direct endpoints: Direct API connections to AI providers headquartered in jurisdictions without adequate data protection are prohibited. See Privacy Policy §7.2 for the full list.
