US Center for AI Standards and Innovation (CAISI)
The US government's frontier-AI evaluation body, renamed from the US AI Safety Institute to the Center for AI Standards and Innovation (CAISI) in June 2025 and refocused by the Trump administration toward demonstrable national security risks -- cybersecurity, biosecurity and chemical weapons -- alongside assessing foreign AI systems for backdoors and covert malicious behavior. CAISI expanded pre-deployment testing agreements to five frontier labs (adding Google DeepMind, Microsoft and xAI to existing partners OpenAI and Anthropic) in May 2026 and had completed over 40 model evaluations, including of systems never publicly released, by early May 2026, though its inaugural director resigned just three months into the role.
