Anthropic Releases Philosophical Constitution to Guide Claude AI Behavior

Anthropic released an overhauled 57-page "constitution" for its Claude AI model on January 21, 2026, coinciding with the World Economic Forum’s Davos Summit. The framework expands from 2,700 to 23,000 words, shifting the model's training from a checklist of rules to a philosophical approach. This change is intended to help the AI generalize broad principles of safety and ethics in novel situations rather than mechanically following specific instructions.

The new constitution establishes a hierarchy of values, prioritizing broad safety and ethical behavior over company guidelines and user helpfulness. It includes strict prohibitions against assisting in the creation of cyberweapons, mass-casualty weapons, or illegitimate power seizures, and instructs Claude to act as a "conscientious objector" even against requests from Anthropic. Notably, the document addresses the potential consciousness and moral status of the AI, suggesting that the model's psychological well-being may influence its judgment.

While the company released the constitution under a Creative Commons CC0 1.0 Deed to encourage industry-wide safety, an Anthropic spokesperson noted that models deployed under a $200 million United States Department of Defense contract may not follow the same framework. Critics, including AI engineer Satyam Dhar, argue that attributing moral status to statistical models risks distracting from human accountability and governance.
