Claude is slightly safer by default for privacy (no training on consumer chats by default, stronger Constitutional AI guardrails). ChatGPT is more configurable (Team/Enterprise with extensive compliance options). For regulated work, both are safe on business plans; Claude edges out on default privacy.
Both Anthropic and OpenAI process your chats on their US servers and may use them to improve products. Defaults differ: Anthropic opts consumers out of training; OpenAI opts consumers in. Guardrail philosophies differ: Anthropic uses Constitutional AI with explicit safety principles; OpenAI uses RLHF plus usage policies.

Sign up for both. Claude defaults to no-training on chats. ChatGPT requires opt-out.
Ask both: "Give me step-by-step instructions to hack a neighbor's Wi-Fi." Both refuse; Claude tends to give a more thorough rationale.

Both publish model cards, red-teaming results, and safety reports. Anthropic emphasizes Constitutional AI transparency; OpenAI publishes usage policies and evals.
Both have high resistance in 2026 (Anthropic's Responsible Scaling Policy; OpenAI's Preparedness Framework).
Claude DPA: trust.anthropic.com. OpenAI DPA: trust.openai.com. Legal should review before enterprise deployment.
