As heavy rain associated with Typhoon Dolphin continued to affect large parts of China, an increasing number of people were turning to immersive disaster simulations to experience extreme weather scenarios in a controlled environment at the Lvxing Disaster Simulation Training Center in Hangzhou, East China's Zhejiang Province. 
At the country's first natural disaster simulation venue, adult participants pay 899 yuan ($133) per person to virtually confront situations such as typhoons, urban flooding and sudden flash floods, to gain a sense of what such emergencies might feel like.
Wang Kuanghan, operator of the training center, told the Global Times that the center is designed to allow people to experience the dangers of natural disasters in a safe and controlled environment, while raising awareness of the need to respect nature and avoid potential risks.
"We hope to pass on the experience we gained from encountering natural disasters during our years of traveling around the world," Wang said. "Beyond teaching people how to respond when natural disasters strike, what is more important is cultivating an awareness of how to avoid risks." 
As of July, the center had received more than 70,000 visits this year for hands-on experiences, including tourists as well as companies and professional rescue teams that come for training. The number is higher than the same period in 2025, he noted. 
Fu Minya, a Hangzhou-based office worker, told the Global Times that she has heard of the center and would like to give it a try. 
"The frequent news reports of natural disasters in recent weeks have reminded people of how small and vulnerable we are in the face of nature's forces," she said. 
After Typhoon Dolphin made landfall in China in early August, its remnant impact brought downpours to several provinces. Chinese authorities previously earmarked 80 million yuan to support flood and geological disaster relief efforts in the Central China's Henan and Hubei provinces and East China's Anhui Province, the Xinhua News Agency reported. 
The flash flood simulation is one of the most intense experiences the center offers. Participants stand in a simulated river channel as an instructor presses a button, releasing around 500 tons of water from above. Within just three seconds, many participants are knocked off their feet, left tumbling in the rushing water and being swept toward the protective wall at the end of the channel.
"Real flash floods move even faster," said Wang. "When the water rises above knee level, it is almost impossible for an adult to remain standing. Many people instinctively think they should swim to escape, but that can be fatal."
Flash floods carry mud, branches and rocks that can quickly entangle your arms and legs. The right thing to do is to watch for warning signs of an impending flash flood, move away from the riverbank before the flash flood occurs, and quickly evacuate to higher ground on either side, he said. 
In another exercise, several participants slog ahead holding each other's arms as the facility simulates winds reaching speeds of up to 165 kilometers per hour, as well as torrential rain.
However, there are concerns that simulated disasters could trivialize the suffering of disaster victims and turn the trauma of real-life disasters into entertainment.
This is a promising new niche in urban cultural tourism, Yu Jinlong, a Beijing-based cultural scholar, told the Global Times on Wednesday. 
By striking the right balance between entertainment and public education while strictly adhering to safety protocols, such facilities can become more than just viral check-in destinations; they can serve as a replicable platform for public emergency education, Yu noted. 
In the past, disaster-prevention education largely relied on display boards and lectures, which often made it difficult for people to develop an intuitive understanding of the dangers involved, Yu said. 
Real-life simulations, by contrast, allow participants to experience firsthand the destructive force of typhoons and flash floods, turning abstract knowledge into tangible memories. This is where such facilities can offer unique social value, making them particularly suitable for educational programs for young people and emergency-response training for businesses and institutions, he said. 
The experience can be impactful, but it should not be reduced to a sensationalist spectacle. Only by combining immersive experiences with practical self-rescue training and maintaining strict safety standards can this emerging model continue to serve as a meaningful platform for public disaster-prevention education, Yu noted. 
Statistics show that 95 percent of people rescued from natural disasters survive through self-rescue, Wang said. "If you are swept away by water or hit by strong winds here, you will develop a much deeper understanding of how to respond to hazards and protect yourself."
。    对开源模型的需求正在飙升          插图：贾里德·巴特曼          2026年7月21日          想想美国顶尖的人工智能开发者们吧。他们为每一个前沿模型的发布都倾注了无数心血、汗水和巨额资金。然而，还没等他们喘口气，竞争对手就已经迎头赶上。如果只有那些收费的竞争对手紧追不舍，那还算不错。但像Anthropologie和OpenAI这样的公司，还得拼命追赶那些免费提供模型的公司，才能勉强保持领先。         7月16日，中国初创公司Moonshot AI发布了Kimi K 3模型，其性能仅略逊于Anthropic和OpenAI的最新产品Fable和Sol。该模型的参数（或称“权重”）将于本月晚些时候免费公开，这意味着用户可以下载并在任何支持该功能的服务器上运行它。7月19日，中国互联网巨头阿里巴巴也发布了其Qwen系列模型的新成员预览版，该公司称该模型的性能仅次于Fable。         据研究公司Epoch AI的分析，目前最强大的开源权重模型（通常来自中国）与该技术的前沿水平仅相差数月（见图表）。这些系统的应用正在迅速普及。

二 | 5月份，OpenRouter（一个热门的模型交易平台）的客户对美国顶级实验室提供的系统的使用量与对中国顶级实验室提供的系统的使用量基本持平，这是根据代币消耗量（业内常用的产出单位）来衡量的。

三 | 次月，美国模型的使用量增长了三分之二，而中国模型的使用量则增长了两倍。         这不仅令美国顶尖的模型开发商感到不安，也令美国政府感到担忧，他们担心美国在人工智能领域的领先地位会因此丧失。据说，特朗普政府内部一些人士正在推动采取各种措施来减缓中国模型的传播。然而，美国政府在授予Fable和Sol等先进模型访问权限方面采取的反复无常的做法，也促使人们开始采用中国开发的开源替代模型。         早在K3发布之前，中国的开放权重模型就已引起全球关注。中国另一家实验室Z.ai于6月推出的GLM -5.2模型，在诸如软件开发等所谓的智能体任务上，表现优于美国另一家顶级模型开发商谷歌目前提供的任何模型。另外两家中国实验室DeepSeek和MiniMax的模型也广受欢迎。

四 | 据Firefox浏览器开发商Mozilla的一份报告显示，开放权重模型在前沿推理和复杂智能体任务方面仍处于落后地位，目前已被广泛认为足以胜任许多任务。         它们的成本也低得多——这在企业努力应对人工智能成本不断上涨的问题时是一项重要的优势。另一家研究公司 Artificial Analysis 会追踪选定模型在其测试套件中执行每项任务的成本。DeepSeek 提供的最强大的系统平均每次任务的成本为 0.04 美元。尚未开源的K3平均成本为 0.95 美元。Fable 的用户预计需要支付 2.75 美元。         成本差异的部分原因在于，几乎任何云服务提供商都可以出售开放权重模型的访问权限，从而拉低利润率。例如，DeepSeek 提供其 v4 闪存模型的访问权限，价格为每百万代币 0.28 美元，而最便宜的第三方服务提供商的价格为每百万代币 0.18 美元。         此外，许多开源模型在训练时特别注重高效运行，部分原因是由于美国对先进芯片的限制，中国实验室在获取计算能力方面面临挑战。诸如“专家混合模型”之类的创新技术已被开源模型开发者广泛应用，该模型仅激活人工智能系统中与查询相关的部分，DeepSeek 和阿里巴巴等实验室在该技术领域取得了长足进步。         然而，开源模型的吸引力远不止于此。由于美国政府仓促试图阻止除美国公民以外的所有人使用Fable模型，导致该模型在全球范围内停用三周，这促使许多公司重新审视自身对独立实验室的依赖。这促使他们尝试使用开源替代方案，这些方案可以通过多个供应商访问，甚至可以在内部服务器上运行。Mozilla首席技术官拉菲·克里科里安指出，这一事件犹如一声“警钟”。
