Anthropic just updated Claude’s “Constitution” — the 80-page living document that lays out the principles the chatbot is supposed to follow — and it’s a reminder that AI safety isn’t something you set once and forget. The company first published Claude’s Constitution back in 2023 as part of its “Constitutional AI” approach, where Claude is trained to follow a written set of ethical guidelines instead of relying mainly on human feedback. The new version keeps the same overall philosophy, but adds more nuance and detail around safety, ethics, and how Claude should handle tricky real-world situations.
A lot of this is Anthropic leaning into the reputation it’s been building for years: the careful, safety-first alternative to flashier AI competitors. The updated Constitution is split into four core values — being broadly safe, broadly ethical, compliant with Anthropic’s rules, and genuinely helpful — and it goes deeper on what those ideas actually mean in practice. On safety, for example, Anthropic says Claude should steer users toward emergency services or basic safety guidance if there’s a risk to human life, and it’s designed to avoid the kinds of harmful chatbot behavior that have caused problems elsewhere. It also spells out hard lines Claude won’t cross, like refusing to discuss things such as developing biological weapons.
