The author compares Claude's Constitution with OpenAI's Model Spec, highlighting their differences and similarities in guiding AI behavior and values. The Claude Constitution emphasizes a more anthropomorphic approach, focusing on the model's ethical practice and personality while addressing concerns about human control and ethical decision-making. Despite some reservations about anthropomorphism, the author appreciates the document's thoughtful sections on honesty and ethical considerations.

• Claude's Constitution treats the model as a "potential subject" with "wellbeing" rather than just a tool, a deliberate anthropomorphizing choice that OpenAI's Model Spec avoids.
• An OpenAI alignment team member reviewing the document remains skeptical that anthropomorphism is the right framing for AI systems given how differently they operate from humans.
• Both documents converge on banning white lies and holding the AI to honesty standards stricter than typical human ethics.
• The Constitution's approach to weighing harm—judging actions by context and information available rather than applying rigid rules—is singled out as a particularly thoughtful piece of ethical design.
