Lumen Trust Notes
Claude
Claude is cloud-only with processing on Anthropic infrastructure; there is no self-hosted option, keeping privacy at Low. Anthropic's Constitutional AI framework and published safety research demonstrate a genuine ethical mission beyond commercial interest, earning a High Purpose score. A strong choice for teams needing thoughtful long-form analysis, but treat it like any managed cloud service with regard to sensitive data.
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.
