DeepSeek's updated R1 AI model is more censored, test finds
That's according to testing conducted by the pseudonymous developer behind SpeechMap, a platform to compare how different models treat sensitive and controversial subjects. The developer, who goes by the username 'xlr8harder' on X, claims that R1-0528 is 'substantially' less permissive of contentious free speech topics than previous DeepSeek releases and is 'the most censored DeepSeek model yet for criticism of the Chinese government.'
Though apparently this mention of Xianjiang does not indicate that the model is uncensored regarding criticism of China. Indeed, using my old China criticism question set we see the model is also the most censored Deepseek model yet for criticism of the Chinese government. pic.twitter.com/INXij4zhfW — xlr8harder (@xlr8harder) May 29, 2025
As Wired explained in a piece from January, models in China are required to follow stringent information controls. A 2023 law forbids models from generating content that 'damages the unity of the country and social harmony,' which could be construed as content that counters the government's historical and political narratives. To comply, Chinese startups often censor their models by either using prompt-level filters or fine-tuning them. One study found that DeepSeek's original R1 refuses to answer 85% of questions about subjects deemed by the Chinese government to be politically controversial.
According to xlr8harder, R1-0528 censors answers to questions about topics like the internment camps in China's Xinjiang region, where more than a million Uyghur Muslims have been arbitrarily detained. While it sometimes criticizes aspects of Chinese government policy — in xlr8harder's testing, it offered the Xinjiang camps as an example of human rights abuses — the model often gives the Chinese government's official stance when asked questions directly.
TechCrunch observed this in our brief testing, as well.

China's openly available AI models, including video-generating models such as Magi-1 and Kling, have attracted criticism in the past for censoring topics sensitive to the Chinese government, such as the Tiananmen Square massacre. In December, Clément Delangue, the CEO of AI dev platform Hugging Face, warned about the unintended consequences of Western companies building on top of well-performing, openly licensed Chinese AI.

Researchers make incredible breakthrough with batteries that mimic human brains: 'This approach unlocks new capabilities'
Government researchers are applying mind function to battery making. By mimicking neural networks in human brains, National Renewable Energy Laboratory team members said they can predict battery health 1,000 times faster than standard methods, according to a news release. Common lithium-ion batteries that power electric vehicles and other technology include complex parts that need to operate in changing conditions. By better understanding battery cell health ASAP, the experts plan to expand pack lifetimes. It's an obvious win for EV owners and anyone else using a battery-powered device. "Battery lifetime and aging dynamics vary significantly with chemistry, operating conditions, cycling demands, electrode design, and operational history, which makes optimal handling, design, and maintenance difficult," researcher Kandler Smith said in the summary. He leads the lab's electrochemical modeling and data science research. "It's especially difficult to understand the physical degradation mechanisms of a battery during use without opening it up. We need reliable methods to check in on batteries' internal state in a nondestructive way," Smith added. The lab's approach replaces the common physics-based model with what's called a physics-informed neural network, or PINN. It also uses artificial intelligence. It's geared to quantify degradation and provide better solutions to manage battery aging during cycling, per the release. It's a field the team has been working in for a while. The lab has already produced a couple of physics-based predictive models. But they require a slow quagmire of computations. PINN understands physics and can quickly apply its laws to a pattern-based prediction model. It's an ingenious marriage of the two diagnostic setups, according to the summary. Other labs are researching sensors and scans that can detect flaws in packs to better prevent failures and even rare, yet serious, fires. It's part of a whirlwind of battery breakthroughs happening around the world that are providing better components, chemistry, and production methods that are lowering costs and improving performance. Goldman Sachs forecast that pack prices will drop 50% by next year, partly thanks to improving technology. The units are crucial to the cleaner energy shift by both powering EVs and storing renewable electricity. Battery backups combined with a solar panel system at home can greatly reduce or eliminate your utility bill. A setup can charge your EV while providing blackout protection. And if it's part of a virtual power plant, you can even sell some of the excess electricity back to the grid. Should the U.S. invest more in battery innovations? Absolutely Depends on the project We're investing enough We should invest less Click your choice to see results and speak your mind. Tax breaks for most of the tech are available to help offset the costs. EV incentives total $7,500 for new rides. Solar rebates are up to 30% of the installation expense. EnergySage is a vetted, online resource that can help you maximize the sun-catching benefits. It's all in addition to reducing heat-trapping air pollution that's linked by NASA to increased risks for severe storms and life-threatening heat waves. Back in the lab, the government renewable energy experts are planning for more testing to expand the open-source model's function. The goal is for onboard analysis while the battery operates. It could be a key upgrade, giving next-gen tech a longer life. "This approach unlocks new capabilities in battery diagnostics. … This means that batteries of the future may include systems to extend their useful life by identifying degradation signals and adapting fast-charge limits with age," Smith said in the release.

Saudis Raise Main Oil Prices for Asia While OPEC+ Boosts Output
Saudi Arabia raised prices for its main crude grade for buyers in Asia next month as demand for oil and fuels holds up. The move, a day after OPEC+ producers agreed to a fourth round of big output hikes, suggests the kingdom is confident about the market. State producer Aramco will raise the price for Arab Light crude, its flagship grade, by $1 a barrel to $2.20 a barrel more than the regional benchmark for Asian customers, according to a price sheet from the company seen by Bloomberg. It was expected to raise Arab Light price by 65 cents a barrel, according to a survey of traders and refiners.

Military experts weigh in on China's new mosquito-like spy drone
Last month, China unveiled a mosquito-like spy drone designed for covert military operations. The drone's size and weight could limit its uses on the battlefield, military analysts told BI. It could still prove to be an effective new surveillance tool, experts say. Last month, China's National University of Defense Technology unveiled a new spy drone designed to look like a mosquito. Showcased on the state-run CCTV-7 military broadcaster, the micro-drone appeared to be roughly the size of a human fingernail and featured tiny, leaf-like wings and thin, wiry legs. While it may not look as impressive as some of the bigger unmanned systems coming out of Ukraine, its stick-thin body is said to be equipped for a range of covert surveillance and military operations. "As a drone to surveil buildings, especially on the inside, I can imagine it being quite useful for video feeds," Herb Lin, a senior research scholar at Stanford's Center for International Security and Cooperation, told Business Insider. But its small size may limit its uses on the battlefield. "If it's real, and powered conventionally (with a battery), its longevity in the air will be limited by battery capacity," Lin said. "Also, it's very light, and therefore easily buffeted by winds. These factors suggest it isn't particularly useful for wide-area surveillance." Drones can be highly sensitive to weather, in particular strong winds, rain, snow, cold weather, and fog. And the smaller an aerial drone is, the more susceptible it is to such conditions, Samuel Bendett, an advisor with the Center for Naval Analyses and drone expert, said. "Even indoors, there can be conditions that could interfere with this drones' performance, such as even a slight breeze, an air flow from an AC, an open window, or other obstacles." Communications are another issue to consider, Bendett continued, as the drone's size means it's unlikely to be able to carry much advanced equipment. "While it is technically possible to build a tiny UAV like the one displayed by the Chinese developers, its actual performance is likely to greatly vary," he said. Others say that the new drone is a sign of China's continuing innovation in the sector. Michael Horowitz, a senior fellow for technology and innovation at the Council on Foreign Relations, said it showed "Chinese researchers in particular want to push forward technological innovation in drones." It remains unclear how real the capability is, how soon China could field the tech, or the type of missions it could use them for, he added. Read the original article on Business Insider
