Microsoft, Google DeepMind, and xAI Grant U.S. Government Pre-Release Access to Frontier AI Models

Microsoft, Google DeepMind, and xAI have each signed formal agreements with CAISI—the Center for AI Standards and Innovation at NIST—granting the U.S. government pre-release access to frontier AI models for national security evaluation. The agreements extend a program that previously covered only Anthropic and OpenAI, and align with directives in America's AI Action Plan. Developers provide model versions with safety guardrails removed so government evaluators can probe for national security risks, including in classified testing environments. CAISI has already completed more than 40 such evaluations, including models not yet publicly available.
