Microsoft president: US AI regulation lacks clear rules

Microsoft president Brad Smith says the US now has AI regulation without transparent or complete rules, warning that businesses cannot plan without them. The Commerce Department used export-control law to pull Anthropic's Fable 5 and Mythos 5 models worldwide, citing cybersecurity risk. Officials also pressed OpenAI to delay GPT-5.6's public launch, giving early access only to government-vetted partners.
