US tightens AI chip export rules ahead of Trump's inauguration

The U.S. has announced new restrictions on AI chip exports, limiting advanced graphics processing units to select countries. Allies like the UK and Japan are exempt, while adversaries such as China and Russia face strict bans. The new rules require licenses for exports to over 120 nations, with special statuses available for entities meeting security standards. Smaller chip orders for research will not need licenses. The tech industry has criticized the policy, with Nvidia calling it misguided. The rules will take effect in mid-May, allowing time for adjustments under the incoming Trump administration.
