来自Betterup Labs和Stanford社交媒体实验室的研究人员介绍了“ Workslop”一词,以描述低质量的AI生成的内容,这些内容已通过,但无法有效地推进任务。这个概念可以解释为什么95%的组织由于如此无益或不完整的工作而认为其AI投资没有回报。一项对1,150名美国员工的调查发现,过去一个月,有40%的员工收到了Workslop。研究人员建议领导者为AI使用制定明确的准则,以避免此问题。

Ron DeSantis' latest AI warning: Big Tech wants your power, water Florida Governor Ron DeSantis is taking a强硬立场反对人工智能公司利用公共资源,特别是在电力和水资源方面。他警告称,AI公司的巨大数据中心可能会导致电费上涨,并影响居民的用水量。DeSantis承诺在佛罗里达州,不允许这些公司将成本转嫁给普通民众,并表示将出台相关政策来保护该州居民的利益。 'This is going to be a big time flashpoint.' Artificial Intelligence may be the wave of the future and the ultimate support for the U.S. stock market. Yet for Gov.  Ron DeSantis , Big Tech wants to create big problems for normal people. And he promises that in Florida, AI companies won’t be allowed to take utility resources from normal people. “I’m going to be very clear. I am not going to let a data center pass on the cost to you and have your electricity bills go up even more than they are. Electricity is skyrocketing throughout the United States of America, and part of it is because they use so much power. We don’t have enough grid capacity to be able to handle all of this stuff. So in Florida, you got to pay your own way,” DeSantis told the Police Benevolent Association on Saturday. He took specific issue with a data center controlled by Meta’s  Mark Zuckerberg , which he said was “as big as Manhattan” and was among those that use as much power as cities with half a million people. “We should not be making you pay more. We should not be saying you don’t have access to the amount of water that you need because they’re doing this stuff. And we’re seeing that across the country. You know, there’s some parts of the country, they’ll build one of these things in these rural areas and they limit when the residents can shower, because they don’t have enough water for all this stuff. So this is going to be a big time flashpoint,” DeSantis said. “I’m on the side of protecting the hardworking people of this state.” This is just the latest DeSantis denunciation of unintended consequences of AI to a police group. “People are going to use AI to scam, to cheat, to steal, to harm people. And I think we’re going to have to come to grips. I mean we’re going to be working on a policy for Florida, and it may require some legislation to be able to provide adequate protections for folks,” DeSantis said at the  2025 Florida Sheriffs Association Summer Conference in July.

How South Korea plans to best OpenAI, Google, others with homegrown AI South Korean tech firms and startups are developing本土大型语言模型,准备与OpenAI和Google等全球巨头竞争。上个月,韩国推出了迄今为止最雄心勃勃的国家人工智能倡议,承诺向五家本地公司提供5300亿韩元(约39亿美元)的资金,用于构建大规模基础模型。政府每六个月将评估首批入选公司的进展,并继续资助领先者直到只剩下两家负责领导国家的人工智能努力。LG AI Research、SK Telecom、Naver Cloud和新兴创业公司Upstage等被选中的公司正在通过不同的优势参与韩国的AI竞赛。例如,LG AI Research提供Exaone 4.0模型,该模型结合了广泛的语言处理能力和先进的推理功能,并且计划通过访问行业数据来改进其AI模型,以实现比通用型模型更多的实际价值。 Image Credits:Anton Balazh / Shutterstock From tech giants to startups, South Korean players are developing large language models tailored to their own language and culture, ready to compete with global heavyweights like OpenAI and Google. Last month , the nation launched its most ambitious sovereign AI initiative to date, pledging ₩530 billion, (about $390 million), to five local companies building large-scale foundational models. The move underscores Seoul’s desire to cut reliance on foreign AI technologies, hoping to strengthen national security and keep a tighter control over data in the AI era. The organizations picked by the Ministry of Science and ICT to compete were LG AI Research , SK Telecom , Naver Cloud , NC AI , and the startup Upstage . Every six months, the government will review the first cohort’s progress, cut underperformers, and continue funding the frontrunners until just two remain to lead the country’s sovereign AI drive. Each player is bringing a different advantage to South Korea’s AI race. TechCrunch spoke with several of the selected companies about how they plan to take on OpenAI, Google, Anthropic and the rest on their home turf. NC AI declined to comment. LG AI Research, the R&D unit of South Korean giant LG Group, offers Exaone 4.0 , a hybrid reasoning AI model. The latest version blends broad language processing with the advanced reasoning features first introduced in the company’s earlier Exaone Deep model. Exaone 4.0 (32B) already scores reasonably well against competitors on Artificial Analysis ’s Intelligence Index benchmark (as does Upstage’s Solar Pro2 ). But it plans to improve and move up the ranks through its deep access to real-world industry data ranging from biotech to advanced materials and manufacturing. It’s coupling that data with a focus on refining the data before feeding to the models to train. Instead of chasing sheer scale, LG wants to make the entire process more intelligent, so its AI can deliver real, practical value that goes beyond what general-purpose models can offer. “This is our fundamental approach,” co-head Honglak Lee told TechCrunch. LG is improving its models via familiar tactics: offering them through APIs, then using the real-world data generated by users of those services to train the model to improve. “As LG’s models improve, our partners can deliver better services, which in turn generate greater economic value and even richer data,” he said. However, instead of chasing massive GPU clusters, LG AI Research is focusing on efficiency, getting the most out of every chip, and creating industry-specific models, he mentioned. The goal isn’t to outspend the global giants but to outsmart them with high-performing, yet more efficient, AI.
