US Government Prepares AI Model Vetting System; GPT-5.5 Instant, Claude Finance Agents, Pentagon AI Partnerships

The White House is preparing an executive order to create an FDA-style vetting system for new AI models, prompted partly by Anthropic's Mythos model disclosing cybersecurity risks; the Commerce Department separately expanded a voluntary testing program with Google, Microsoft, and xAI. OpenAI rolled out GPT-5.5 Instant as the default ChatGPT model, claiming 52.5% fewer hallucinations on high-stakes prompts. Anthropic released ten financial agent templates running on Claude Opus 4.7, while the Pentagon expanded AI vendor agreements to include Microsoft, Amazon, Nvidia, and Reflection AI after canceling its Anthropic contract over autonomous weapons restrictions. Major pharma companies report AI gains primarily in manufacturing optimization rather than drug discovery breakthroughs.
