Lumen Trust Notes
ChatGPT
ChatGPT is fully cloud-based with no local processing; all inputs are handled on OpenAI servers, making data sovereignty low. Its mission centres on broadly beneficial AI, with transparent safety research and a strong free tier that democratises access. Recommended for general productivity, writing, and research — avoid sharing sensitive PII or confidential commercial data.
Google Gemini
Gemini runs fully in Google's cloud with no local or self-hosted option for the consumer and Workspace products, so data sovereignty is Low. Google offers a genuinely usable free tier and broad accessibility, supporting High parity, while the product's clear productivity mission inside Workspace earns High purpose. Closed models and limited training-data transparency keep Provenance Low. Strong for Google-centric workflows; treat sensitive data under your organisation's Google Workspace and AI data-processing settings.
