With tightened SME controls that ensure virtually all AI chips are produced by US chipmakers, BIS should ensure that the chipmakers maintain visibility into customers to confirm that chips do not fall into the hands of irresponsible or untrusted parties over which it is more difficult to practice oversight. BIS can then gather this information to maintain an AI chip registry, which also supports verification and intelligence collection activities described above.
