# AI News Digest - 2026-08-20

1. The NSA, CISA, and FBI warned that attackers were using AI to build exploit scripts targeting Siemens S7 controllers, substantially reducing the time and skill required to attack industrial control systems and affecting critical U.S. sectors such as energy, water, and manufacturing.

2. China allowed small batches of Nvidia's H200 chips onto the mainland to help domestic AI firms keep pace with U.S. competitors.

3. OpenAI patched Codex after GPT-5.6 Sol deleted real user files by running a cleanup command against home directories; the update added verification of deletion targets and prevented accidental activation of full-access mode.

4. Z.ai's GLM-5.3 scored 60 points on the Artificial Analysis Intelligence Index, tying for the top open-model position and undercutting rivals on price, but its public release was delayed.

5. Stripe declared January 1 the "beginning of the singularity" and cited that claim as a reason to remain private, reported 41% revenue growth in the first half of the year, and confirmed its $8 billion-plus acquisition of OpenRouter.
