"All lawful purposes"

Anthropic, the AI safety-focused company behind Claude, has released a significant policy statement titled 'All lawful purposes' to clarify the boundaries of its acceptable use policy. The core announcement is a firm prohibition against using Claude for military and warfare applications, including weapons development, warfare, and any activity intended to cause harm. This formalizes Anthropic's ethical stance, drawing a clear line that distinguishes its models from being used as tools of conflict, even as other AI providers engage with defense departments. The statement serves as a direct response to growing questions about the role of advanced AI in national security and defense sectors.

While banning harmful military uses, the policy carves out a nuanced space for beneficial government work. Anthropic states it will continue to allow use by government and national security organizations for non-harmful purposes, such as cybersecurity threat detection, disaster response planning, and administrative tasks. This distinction aims to prevent the company's technology from being weaponized while acknowledging that AI can support legitimate, safety-critical government functions. The move establishes Anthropic as taking a more restrictive public stance than some competitors on military AI, potentially influencing industry norms and customer expectations around ethical AI deployment.
