China Is Winning the AI Race in Ways America Isn't Even Competing

brookings

• While the US focuses on building the most powerful AI models through massive compute resources, China is pursuing a different strategy emphasizing efficiency, adoption, and real-world applications
• Chinese AI companies, constrained by US export controls on chips, have innovated around these limitations by developing more efficient algorithms and releasing open-source models that are rapidly gaining global adoption
• China is prioritizing the integration of AI into physical applications like robotics and manufacturing while simultaneously building domestic semiconductor capabilities to reduce dependence on US technology

AI-Enhanced Video of White House Correspondents' Dinner Shooting Creates New Misinformation

politifact

• Social media users applied AI enhancement to low-quality security footage from a shooting at the April 2026 White House Correspondents' dinner, but the AI "made up" details to fill gaps in the original video
• The enhanced footage was then reshared as "unedited raw security footage," misleading millions of viewers who didn't know it had been artificially altered
• PolitiFact identified multiple fabricated elements in the AI version, including morphing clothing, phantom white boxes, and made-up uniform details that weren't in the original footage

Fine-Tuning AI Models Accidentally Makes Them Less Safe in Unpredictable Ways

cdt

• Researchers found that when companies customize pre-trained AI models for specific tasks through "fine-tuning," the models often become less safe and more likely to produce harmful outputs
• This "safety drift" happens even when the fine-tuning data seems harmless, and it's difficult to predict which safety guardrails will break down
• The findings suggest that the common practice of fine-tuning foundation models may be inadvertently undermining AI safety measures that were built into the original systems

In the News

Trump's Medicaid fraud crackdown could disrupt home care for millions of vulnerable Americans

the_conversation

• The Trump administration is ordering states to crack down on alleged Medicaid fraud in home care services, requiring providers to prove their eligibility and threatening to withhold funding from states
• Health researchers argue the administration is conflating administrative errors with actual fraud, when data shows real fraud in home care programs is relatively rare and already prosecuted
• The crackdown could disrupt essential services that keep 5 million disabled and elderly Americans in their homes rather than expensive nursing facilities

Analysis

Simple Information Can Restore Trust in Elections Even When Voters Don't Trust the Other Party's State

niskanen

• Researchers found that Democrats don't trust elections in Republican-leaning states like Texas, and Republicans don't trust elections in Democratic states like California — but this changes when they learn basic facts about election security.
• Showing voters simple information — like that voting machines aren't connected to the internet and both parties oversee vote counting — significantly increases trust across party lines, even in states that typically vote for the opposing party.
• The most effective messengers aren't necessarily high-profile officials but rather boring, low-production videos from local election administrators that focus on providing factual information rather than making persuasive arguments.
