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.
Perplexity AI
Perplexity processes all queries on cloud infrastructure with no local option, keeping sovereignty low. Its transparent citation model and a genuinely useful free tier represent both an ethical commitment to honest information and broad access parity. Strongly recommended for research, fact-checking, and staying current — treat it as a research assistant, not a replacement for primary source verification.
