On June 6, 2025, Anthropic announced a custom set of Claude Gov models developed exclusively for U.S. national security customers. According to the company, the models are already deployed at "the highest level of U.S. national security," and access is restricted to operators working in classified environments.
Why were the Claude Gov models created?
Anthropic says the Claude Gov models were built using direct feedback from government customers to meet real operational needs. The company also notes that these models underwent the same rigorous safety testing as its other Claude models, with the aim of better addressing the unique requirements of national security users while maintaining Anthropic's stated commitment to safe and responsible AI development.
Intended uses and capabilities
Anthropic describes a range of applications for U.S. national security customers, including strategic planning, operational support, intelligence analysis and threat assessment. The company highlights several specific improvements it attributes to the Claude Gov models:
- Improved handling of classified materials: the models "refuse less" when engaging with classified information, according to Anthropic.
- Greater understanding of documents and information in intelligence and defense contexts.
- Enhanced proficiency in languages and dialects that are critical to national security operations.
- Improved interpretation of complex cybersecurity data for intelligence analysis.
Access and contact information
Anthropic says access to Claude Gov is limited to agencies and operators in classified environments. The announcement does not list specific agencies, disclose technical architecture or detailed testing methods, nor does it provide pricing information. For inquiries about how the Claude Gov models can support an agency’s mission, Anthropic directs public sector customers to its public sector team at pubsec@anthropic.com.
The company frames the announcement as part of its commitment to deliver responsible and safe AI solutions tailored to the needs of U.S. national security customers.
