For American companies building AI today, it’s basically a free-for-all, a self-regulation zone with zero federal restrictions. But for Chinese AI companies, the Chinese Communist Party exerts strict control over AI models. A report in The Wall Street Journal detailed the rigorous tests that AI models are subjected to: they must answer 2,000 questions that are frequently updated and achieve a 95% refusal rate for queries related to forbidden topics, like the Tiananmen Square massacre or human rights violations, according to the report.

On Friday, stocks closed flat amid thin trading volumes, but the S&P 500 notched a 1.4% gain for the week.
