Trump signs executive order allowing pre-release AI models to be submitted for government safety review

特朗普签署行政令：AI 模型在上线前可提交给政府进行安全评估

Trump signed an executive order creating a voluntary cooperation mechanism for AI companies, allowing frontier models to be submitted to the federal government for safety evaluation before release; Google, Microsoft, and xAI have agreed to CAISI verification, while OpenAI and Anthropic joined in 2024.

Why it matters: HKR-H/K/R all pass: a Trump executive order creates a federal pre-launch safety-review path, and Google, Microsoft, and xAI accepted CAISI verification. The mechanism is voluntary, so it sits in must-write policy range, not industry-shaking range.
