CAISI at NIST announced formal agreements on May 5 with Google DeepMind, Microsoft, and xAI allowing government evaluation of frontier AI models before public release, including testing in classified environments with safeguards removed. This expands existing partnerships with Anthropic and OpenAI, renegotiated under Trump's AI Action Plan. The move follows yesterday's NYT report on White House vetting considerations — these are the actual signed agreements implementing that policy.
