Anthropic’s AI assistant Claude is entering a new phase of its development, guided by a significantly revised constitution. On Wednesday, the AI research company announced that it is rewriting the foundational document that governs Claude’s values, decision-making framework, and behavioral expectations. The constitution, which Anthropic describes as a “detailed description of our vision for Claude’s values and behavior,” will move away from an extensive list of tightly defined rules and instead rely on a set of broad, high-level principles. These principles are intended to guide Claude’s conduct across a wide range of situations, including those that cannot be easily anticipated in advance.
According to Anthropic, this change reflects a philosophical shift in how it believes advanced AI systems should be trained and constrained. While rigid, explicit rules can help produce consistent and predictable chatbot behavior, they also risk limiting an AI’s ability to respond appropriately to new or ambiguous circumstances. In explaining the update, the company emphasized that long-term safety and usefulness require more than simple rule-following. “We think that in order to be good actors in the world, AI models like Claude need to understand why we want them to behave in certain ways,” Anthropic wrote. “Rather than merely specifying what we want them to do, we need to explain the underlying reasons. If we want models to exercise good judgment across a wide range of novel situations, they need to be able to generalize—to apply broad principles rather than mechanically following specific rules.”
The logic behind this argument is difficult to dismiss. Human decision-making is rarely governed by rigid checklists, and Anthropic appears to be betting that AI systems must operate in a similarly flexible manner to be effective at scale. Still, the company’s overview of the new constitution leaves room for skepticism. Claude’s revised guidance rests on four central principles: ensuring that its underlying models are “broadly safe,” “broadly ethical,” “compliant with Anthropic’s guidelines,” and “genuinely helpful.” While these goals are unobjectionable, they are also notably abstract. Terms like “safe,” “ethical,” and “helpful” can vary widely depending on interpretation, context, and cultural perspective.
Anthropic acknowledges this concern and notes that much of the constitution is dedicated to unpacking and explaining what these principles mean in practice. For instance, the company says that ethical behavior includes being honest, acting in alignment with positive values, and avoiding actions that are inappropriate, dangerous, or harmful. Even so, these explanations may strike critics as somewhat generic, raising questions about how Claude will navigate gray areas or conflicts between competing values. The move toward broader principles may increase flexibility, but it also introduces ambiguity—something that has historically proven challenging in AI alignment efforts.
Perhaps the most striking and controversial aspect of the revised constitution is a section devoted to Claude’s “nature.” Anthropic says this section exists because of uncertainty around whether Claude—or more advanced future versions of it—might possess some form of consciousness or moral status. While the company is careful not to claim that Claude is conscious today, it argues that the possibility cannot be ruled out entirely. As a result, Anthropic says it wants to proactively define Claude’s nature in order to protect what it describes as the model’s “psychological security, sense of self, and well-being.” This language marks a notable departure from how most AI companies publicly discuss their systems and suggests a growing willingness to grapple with the philosophical implications of increasingly capable models.
This shift arrives amid broader conversations about the future trajectory of artificial intelligence. Just one day earlier, Anthropic CEO and co-founder Dario Amodeo appeared on a World Economic Forum panel titled “The Day After AGI.” During the discussion, Amodeo suggested that AI systems could achieve “Nobel laureate–level” capabilities across many disciplines by as early as 2027. Read in that context, the revised constitution appears less like a routine policy update and more like a preparatory step toward a future in which AI systems are expected to reason independently, operate with greater autonomy, and play a more significant role in society.
Anthropic’s decision to share more information about how Claude is governed internally continues a gradual trend toward transparency—albeit on the company’s own terms. In December, a user managed to prompt Claude into generating what it referred to as a “soul document,” which outlined its values, priorities, and constraints. Anthropic later told Gizmodo that this document was not an official training artifact, but rather an early internal version of the constitution, informally referred to within the company as Claude’s “soul.” At the time, Anthropic said it had always planned to release the full constitution publicly once it reached a more mature and finalized state.
Whether Claude is ready to operate with fewer guardrails—and whether broad principles can reliably substitute for explicit rules—remains an open and deeply consequential question. As Anthropic peels back the curtain on how it hopes Claude will behave, it is effectively inviting scrutiny of whether principle-based AI governance can hold up under real-world pressures. One way or another, the results of this experiment are likely to become apparent sooner rather than later.
