Two bills on halting AI development and banning superintelligence referred to the U.S. Congress

Two separate bills that would pause advanced AI development and ban artificial superintelligence have been introduced in the U.S. Congress and referred to committee, though neither has yet been enacted. Senator Bernie Sanders filed S.5493 on September 23, sending it to the Senate Commerce, Science, and Transportation Committee, while Representative Greg Casar introduced H.R.10538 on September 24, referred to the House Oversight and Government Reform Committee with Representative Yassamin Ansari listed as a cosponsor. The House bill's scope covers systems trained using 10^25 or more integer or floating-point operations. The proposals matter because they would impose the first statutory compute thresholds on frontier AI training if passed. What to watch next is whether the committees schedule hearings or advance the bills, and whether the 10^25-operation trigger survives markup.
